Tornado causes ‘significant damage’ in Selma, Alabama, mayor says, as severe storms rake Southeast



CNN
 — 

A huge tornado that tore through the Alabama city of Selma Thursday caused “significant damage,” Selma’s mayor said – one of more than a dozen twister reports made in that state alone as severe storms tear through the Southeast leaving several injured.

The “large and extremely dangerous tornado” in Selma, confirmed by the National Weather Service, hit the city at 12:19 p.m. CT and continued east, the service said.

“Please refrain from traveling the roadways and stay away from down power lines,” Mayor James Perkins Jr. said in a Facebook post.

What appeared to be an enormous funnel cloud passed through the area, according to images shared by Mike Pitts. After it passed, Pitts’ pictures showed homes without roofs, other roofs shorn of shingles, and roads blocked by piles of debris.

The storm “tore up” Selma resident Krishun Moore’s house, but no one there was injured, she told CNN. She took shelter in a bathroom with her mother.

“All we heard was wind and the whole house was shaking,” Moore said.

Selma, a city of some 17,000 people roughly 50 miles west of Montgomery, is the site of a landmark 1965 civil rights march in which protesters were beaten and tear-gassed by police on the Edmund Pettus Bridge, an incident referred to as “Bloody Sunday.”

The Selma tornado came as severe storms capable of tornadoes are sweeping across the Southeast Thursday, injuring several people and leaving damage in several states with the potential for hours of more destruction ahead.

Ricky Adams, director of field operations with Alabama Emergency Management, said there are no immediate reports of fatalities in the state.

The damage is the worst in Selma, Adams said, “but again, it’s still early and we’re still assessing.”

There are a lot of trees down and rescue operations are slow going, he added.

More than 35 million people in the Southeast and the Ohio Valley – from Louisiana eastward to the Carolinas and from Kentucky south to the Gulf Coast – are under some level of threat for severe storms Thursday that could include damaging wind gusts and tornadoes, the Storm Prediction Center said.

By early afternoon, tornado watches covered parts of Mississippi, Alabama, Georgia, Tennessee, the western Florida Panhandle and far western North Carolina with various expirations.

And more than 360,000 people in the Atlanta metropolitan area were under a tornado warning after a twister was observed near Hartsfield-Jackson Atlanta International Airport. The airport, a hub for Delta Airlines, was under a ground stop as the storm passed through.

Thursday’s greatest risk of severe storms – an “enhanced” risk, or level 3 of 5 – is predicted for about 9.5 million people over parts of Alabama and Georgia, including the Birmingham, Montgomery and Atlanta areas, the prediction center said.

More than 118,000 customers in Alabama, Georgia and Tennessee were without power as of 3:30 p.m. ET, according to PowerOutage.us.

Damage reports across the Southeast and the Ohio Valley were piling up Thursday as storms progressed.

In northern Alabama’s Morgan County alone, a storm caused 10 to 15 injuries Thursday morning – none of which are believed to be life-threatening – and damaged numerous buildings, county sheriff’s spokesman Mike Swafford said.

Streets and fields were littered with debris and downed power lines in Decatur, a Morgan County community roughly 25 miles southwest of Huntsville, pictures from city police and the county sheriff’s department showed.

Siding was ripped off a Decatur hotel, according to pictures taken by hotel guest Mark Spychala, who said he sheltered in a laundry room as the storm hit Thursday morning.

“We lost power, and could hear the wind and rain” pummel the area outside, Spychala told CNN. The National Weather Service preliminarily attributed the Decatur damage to strong winds.

Several preliminary tornado reports were made in the morning in Alabama, including in northwestern Alabama’s Winston County and western Alabama’s Sumter County, where building damage was reported, the weather service said.

Downed trees and power lines were reported along several of the roads of Winston County, whose communities are dozens of miles northwest of Birmingham.

“Motorists are urged to only travel roadways in emergency situations and to remain weather aware,” the Alabama Law Enforcement Agency said in a series of tweets about the Winston County damage.

In northeastern Mississippi’s Monroe County, several rural buildings lay flattened or severely damaged after a storm passed through Thursday morning, video tweeted by the Mississippi Emergency Management Agency shows.

No injuries were reported there, according to the agency, which said a tornado could have caused the damage. The weather service preliminarily said strong winds caused damage in the county.

Wind damage to trees and buildings also were reported in other locations across parts of Mississippi, Alabama and Kentucky before noon, the weather service said.

Major winter storm threatens powerful tornadoes in the South and heavy snow and freezing rain across the Plains and Midwest

A major, multi-hazard storm is barreling across the country on Tuesday and continues to bring the risk of strong tornadoes and flooding to the South, and ice and snow to the Plains and Upper Midwest.

The storm, which triggered deadly floods in California over the weekend, has tracked east and is pulling moisture from the Gulf of Mexico into the South, where above-normal temperatures have set the stage for severe thunderstorms.

More than 35 million people are under some sort of severe weather threat in the South, with the highest risk near the Gulf Coast. Southeast Louisiana and southern Mississippi and Alabama were under a level 3 out of 5 “enhanced” risk of severe weather. Places like Baton Rouge, Montgomery and Gulfport could all see strong storms. A level 2 out of 5 “slight” risk of severe weather covered Nashville, New Orleans and Atlanta.

Strong tornadoes, large hail and wind gusts topping 70 mph are possible in the most extreme thunderstorms.

“Severe convection with all three modes (tornadoes, hail and damaging winds) is likely,” the National Weather Service office in Mobile warned.

Heavy rainfall associated with these thunderstorms could also trigger significant flash flooding across the South. Southeastern Alabama and Southwest Georgia are under a level 3 out of 4 “moderate” risk of excessive rainfall. Portions of Southeast Louisiana, Mississippi, Alabama, Tennessee and Georgia are also under a level 2 out of 4 “slight” risk of excessive rainfall.

Rainfall totals could reach 2 to 4 inches across the South through Wednesday, while some areas could see up to 6 inches.

The system produced dangerous thunderstorms overnight. By 6 a.m., 30 storm reports had been submitted to the National Weather Service, including two tornado reports, 22 high wind reports and six large hail reports. One of the tornadoes that was reported was in Jonesboro, Louisiana, where large trees were knocked downed and damaged. The other was reported in Haywood, Tennessee.

Damage was also reported after a possible tornado in Jessieville, Arkansas, according to Garland County officials.

“Damage was sustained to areas of (a) school due to trees, and power lines. The school was currently in session at the time, however all students have been accounted for and reports of no injury,” the Garland County Sheriff’s Office said in a release.

In Jackson Parish, Louisiana, residents were told to stay off the roads as the severe weather toppled trees and covered roadways with water. Jackson Parish Sheriff’s Department said tarps will be given out to those whose homes are damaged.

“We are trying to work to get to houses that are damaged and clear roads,” the Sheriff’s Department said.

As the risk persists, forecasters have been concerned about tornadoes forming at night, according to Brad Bryant of the National Weather Service office in Shreveport, Louisiana.

“You can’t see them coming. A lot of the time, people are asleep and not paying attention to the weather,” Bryant said. “Many areas around here don’t have good cell phone coverage and storm alerts are not as effective in those areas, especially once people are asleep.”

Anyone in areas at risk of tornadoes should seek safe shelter immediately, Bryant said.

“If you wait around for a warning to be issued, it is too late,” Bryant said Monday. “You need to have a safe shelter plan in place in advance of these storms.”

Damage reports were also coming from across northern Louisiana, including several transmission highline towers being damaged in the Haile community in Marion. One of the towers was knocked over and several others are damaged, according to the National Weather Service in Shreveport.

A wind gust of 81 mph was reported in Adair, Oklahoma – a gust equivalent to a Category 1 hurricane.

As the South braces for floods and tornadoes, the storm continues to bring heavy snow, sleet and freezing rain across the Plains and Upper Midwest on Tuesday, significantly impacting travel.

Over 15 million people are under winter weather alerts from Colorado to Michigan.

Residents in parts of Nebraska, South Dakota and Minnesota are likely to see intense snow rates of 1 to 3 inches per hour.

Blowing and drifting snow on Tuesday may result in snow-covered roads and make it “hazardous, if not impossible” to travel, the weather service warned.

Road conditions were already deteriorating Monday night in northwestern Iowa, northern Nebraska and eastern South Dakota, according to the weather service in Omaha. Portions of northern Nebraska have already reported nearly a foot of snow and could get an additional 12 to 18 inches on Tuesday, according to the weather service.

Roughly 200 miles of eastbound Interstate 80 in Wyoming, from Evanston to Rawlins, are closed due to the ongoing impacts of the storm, according to the Wyoming Department of Transportation. The department said westbound traffic is further blocked from the Rawlins section of I-80 to the Interstate-25 junction in Cheyenne, which covers more than 120 miles.

“Snow (and) blowing snow to impact Wyoming roads into tonight,” an agency Facebook post read. “A high wind event will then create blowing (and) drifting snow, poor visibility and possible whiteout conditions Tuesday afternoon through Wednesday afternoon for sections of I-80, I-25, South Pass and various secondary roads!”

“If you can, please stay home. If you must travel, ensure you have an emergency kit in your car,” the weather service in Sioux Falls told residents, saying travel will become difficult to impossible by Tuesday morning.

A vehicle winter emergency kit includes snacks and water, a battery-powered weather radio, flashlights and batteries, a first aid kit, a shovel and ice scraper, a jumper cable and other items.

Significant ice accumulations from freezing rain are expected, possibly over a quarter inch, from northeastern Nebraska through northwestern Iowa into southern Minnesota.

The freezing rain poses a significant hazard to those on foot. Even a light glaze can make for slippery sidewalks and driveways. Accumulations more than 0.25 inches can cause scattered power outages and break tree limbs, the weather service says.

Tornado threat ramps up as storm damage reported in Oklahoma and Texas and blizzard conditions mount in the northern Plains

Severe storms – with reports of at least one tornado and damaging winds – are raking parts of Oklahoma and Texas, leaving a trail of damage Tuesday morning and threatening more as blizzard conditions build across several states farther north.

This is all part of a giant winter storm system pushing into the central US after walloping the West over the weekend. About 25 million people from Texas to Mississippi are under threat of severe storms Tuesday, including tornadoes. And about 15 million people – largely in the north-central US – are under winter-weather warnings or advisories Tuesday morning, with power outages a key concern.

Two tornado watches are in effect: One for parts of the Dallas area and southern Oklahoma until 11 a.m. CT; and one for for parts of Arkansas, southeastern Oklahoma and eastern Texas until 5 p.m. CT.

A line of severe storms capable of producing tornadoes and large hail was hitting the Dallas/Fort Worth metroplex in the midmorning.

Sirens rang out around 9:30 a.m. ET at Dallas Fort-Worth International Airport. “We are in the midst of a tornado warning here on the western side of the Dallas-Fort Worth area,” CNN’s Ed Lavandera said from the airport, “where essentially everything has come to a halt here (as) this really strong line of severe storms is starting to make its way through North Texas.”

Damage on Tuesday morning includes:

• Wayne, Oklahoma: A suspected tornado in that town left “buildings wiped off of their foundation (and) trees snapped over like twigs” early Tuesday, CNN meteorologist Derek Van Dam said. There are no reported injuries, but Wayne has no power, and family structures, outbuildings and barns are damaged, according to McClain County Emergency Management.

• Outside Dallas: Wind damage has been reported Tuesday morning west of the Dallas/Fort Worth Metroplex, including tractor-trailers being blown over near the towns of Millsap and Decatur, and barns suffering damage near the town of Jacksboro, the National Weather Service said.

More severe storms capable of tornadoes are expected Tuesday and Wednesday in the Gulf Coast region as the complex snow-or-rain system sweeps through the central US from north to south.

Across the central and northern Plains and Upper Midwest, blowing snow and/or freezing rain could snarl travel and threaten power outages into Thursday.

Here’s what different regions can expect in the coming days:

• An “enhanced risk” for severe storms Tuesday stretches from eastern Texas to northern Louisiana and southwestern Mississippi, with tornadoes, large hail and damaging straight line winds possible.

• Blizzard conditions are expected Tuesday and Wednesday for parts of the central and northern Plains, with snow at times expected to fall at rates of 1 to 2 inches per hour amid powerful 40 mph winds.

• The greatest flash flooding threat will be Tuesday into Wednesday from the lower Mississippi Valley into the central Gulf Coast, Tennessee Valley and southern Appalachians.

• Freezing rain and sleet will be possible through Wednesday in the Upper Midwest.

The storm, which first hit the Western US with much-needed snow and rain, resulted in winter storm alerts from the Canadian border to Mexico’s border with New Mexico.

In Denver, up to 5 inches of snow are expected Tuesday, with 50 mph wind gusts possible.

Blizzard warnings extended Tuesday from parts of Montana and Wyoming into northeastern Colorado, western Nebraska and South Dakota, where harsh, life-threatening conditions are expected.

Snowfall through Wednesday morning generally could be 10 to 18 inches in the central and northern Plains and Upper Midwest. Some areas inside the blizzard warning zones – particularly western South Dakota, eastern Wyoming and northwestern Nebraska – could get as many as 24 inches of snow, with winds strong enough to knock down tree limbs and cause power outages, the Weather Prediction Center said.

“We’re not expecting a quick burst of snowfall here,” Brandon Wills, a meteorologist for the National Weather Service in Cheyenne, Wyoming, said Monday evening. Snow is “going to accumulate the highest in the northern Nebraska panhandle – and it’s going to be blowing around like crazy because of the strong winds that we’re going to have as well,” he said.

Interstates in South Dakota could become impassable amid the blizzard conditions, resulting in roadway closures across the state, the South Dakota Department of Transportation warned Monday.

Ice storm warnings were issued for parts of eastern South Dakota, southwestern Minnesota and western Iowa. Up to two-tenths of an inch of ice could accumulate in some of these areas, forecasters said.

In Anchorage, Alaska, an “unprecedented amount of snowfall” has led to schools being closed for four days and on Monday shut down the University of Alaska Anchorage and Alaska Pacific University.

“The snowstorms that have hit Anchorage over the last week are historic in nature, bringing anywhere between 30-45 inches of snow to our city,” said Hans Rodvik, a spokesperson for the Anchorage mayor’s office, said Monday in a statement to CNN.

Meanwhile, the southern end of the storm threatens to bring tornadoes.

A tornado watch is in effect Tuesday morning for parts of Texas and southern Oklahoma until 11 a.m. CT. The main threats are tornadoes, hail and wind gusts up to 70 mph.

An alert for enhanced risk of severe weather – level 3 of 5 – was issued Tuesday for eastern Texas and the lower Mississippi River Valley, with the main threats including powerful tornadoes, damaging winds, and large hail. Baton Rouge, Shreveport, and Lafayette, Louisiana, are part of the threatened area, as is Jackson, Mississippi.

“My main concern with the tornadoes is going to be after dark,” CNN meteorologist Chad Myers said Tuesday. “We have very short days this time of year, so 5 or 6 o’clock, it’s going to be dark out there. Spotters aren’t as accurate when it is dark. Tornado warnings are a little bit slow; if you’re sleeping, you may not get them. So, that’s the real danger with this storm.”

A zone of slight risk – level 2 of 5 – encircled that area, stretching from eastern Texas and southern Oklahoma to southern Arkansas and much of the rest of Louisiana and central Mississippi. That includes Dallas and New Orleans.

Tuesday also brings a slight risk of excessive rainfall in parts of Arkansas, Louisiana and Mississippi, with 2 to 4 inches of rain and flash flooding possible, the Weather Prediction Center said.

On Wednesday, the threat for severe weather is largely focused on the Gulf Coast, with tornadoes and damaging winds possible over parts of southern Louisiana, Mississippi, southwest Alabama and the western Florida Panhandle, the Storm Prediction Center said.

Winter storm pummels western U.S. with snow before taking aim at the South, bringing a multi-day severe storm threat



CNN
 — 

A large winter storm system slammed into the western US over the weekend, blanketing mountain areas with heavy snow before taking aim at the South, where it’s expected to bring severe weather, with strong winds, hail and tornadoes possible.

More than 15 million people in 14 states are under some sort of a winter weather alert as the powerful storm moves across the county.

The storm already brought avalanche warnings to parts of the West, shuttered major highways as conditions became icy and triggered flood watches.

The storm blanketed some mountain areas of drought-parched California with thick snow, including Soda Springs in the northern part of the state, which received 60 inches of snow in 48 hours.

A multi-day severe storm threat begins Monday for parts of the South and southern central US. A slight threat for severe weather has been issued for parts of western and central Kansas and Oklahoma into northwestern Texas.

The threat does, however, strengthen as the system heads east Tuesday, likely impacting a large swath of the Lower Mississippi River Valley. Areas including Baton Rouge, New Orleans and Shreveport in Louisiana and Jackson, Mississippi, could see tornadoes, high wind gusts and damaging hail.

Additionally, the National Weather Service in Denver forecast whiteout and blizzard conditions for Tuesday in parts of the plains in Colorado.

To the east, residents in Fargo, North Dakota, are expected to see snowfall over 6 inches and will be under a winter storm watch from late Monday night until late Wednesday night. Duluth, Minnesota, could also see 6 inches of snow and will be under a winter storm watch starting Tuesday morning.

Though the storm is walloping some areas with severe weather, it’s forecast to track across drought-stricken areas, bringing much needed relief – including to the Mississippi River Valley area, where excessive rainfall is possible Wednesday.

In the Sierra Nevada, snow pack totals are already above average, according to the National Weather Service in Reno.

Winter storm warnings were in place overnight for the Sierra Nevada Mountain Range, where an additional foot of snow could fall in the highest elevations before 4 a.m.

The storm already made for icy and dangerous conditions on key roadways, with authorities on Saturday closing down a long stretch of Interstate 80, from Colfax in Northern California to Stateline, Nevada, due to “blowing snow & near-zero visibility,” Caltrans said on Twitter.

The Tahoe Basin and the Eastern Sierra are seeing snowfall totals that are typically recorded later in the winter, in January.

“The snowpack is about 225% of normal, so it’s more than twice what we’d be expecting this time in December,” said Mark Deutschendorf, forecaster at the National Weather Service office in Reno.

“It looks a lot like Christmas out here,” Deutschendorf said. “It didn’t come with a lot of wind, and it stuck to everything. It’s like a picture postcard.”

While he noted the snow totals so far are impressive, Deutschendorf said he is “cautiously optimistic” about this precipitation putting a big dent in the state’s drought.

“We had a similar run of storms last year. We had a nice head start, and then January through March were incredibly dry,” Deutschendorf explained.

In California, 48 inches of snow fell in Twin Bridges in a 48-hour period, 46 inches fell in Tahoe-Donner, 45 inches in Donner Peak and 44 inches at Palsades Tahoe Ski Base.

“We’re Buried,” the Palisades Tahoe Ski Resort wrote on its website Sunday, sharing photos of thick snow covering the ski resort in Olympic Valley, California.

“This is definitely a storm to remember. We’ve now received 7.5 feet of snow since December 1st. Plus, in just 24 hours from Saturday morning to Sunday morning, we received more than 35 inches of snow — the 6th largest snowfall total in 24 hours that we have on record,” resort operators wrote.

And in Southern California, residents were under warnings and watches amid heavy rain and localized flooding.

Major storm to bring feet of snow, heavy rain and possible tornadoes



CNN
 — 

An atmospheric river event, bringing ample amounts of moisture to the West this weekend, will gradually move across the country and bring hazardous weather to millions.

The blockbuster storm will begin in the West with heavy snow, gusty winds, and coastal flooding, then move eastward, threatening potential blizzard conditions in the Midwest and tornadoes in the South.

“Extreme snowfall is likely across the Sierra and northern California ranges,” on Saturday the Weather Prediction Center said. Adding that, “prolific snowfall rates of 3 inches per hour are expected in the Sierra Nevada accumulating to more than 5 feet through Sunday in some areas.”

More than a dozen western states are under winter weather alerts this weekend as the potent storm system moves across the region.

Snow will be measured in feet across the Sierras, Rockies, and Cascades. Heavy rain will also be notable up and down the West Coast, particularly in California, where flooding concerns exist through Sunday.

An atmospheric river is a plume of moisture which streams in off the Pacific Ocean. Similar to a fire hose, it shoots moisture into one area for an extended period of time, resulting in very heavy rain or snow.

Most coastal communities will pick up 1 to 3 inches of rain through the weekend, and some areas of northern and central California could receive 3 to 5 inches of rain in total. Coastal erosion and flooded roadways will be the main concerns.

“Additional heavy rains may result in isolated runoff issues, especially across recent burn scars,” the Weather Prediction Center said.

Hurricane-force wind gusts of 80 to 100 mph are also possible across the mountain ranges Saturday which will cause blowing snow leading to near zero visibility and difficult to impossible travel conditions.

“Gusty winds and heavy snow could bring down tree branches,” the National Weather Service office in Sacramento, California, said, which could lead to “near whiteout conditions at times.”

And the western US will not be the only area affected by the storm.

“As the system moves into the Plains early next week, a springlike storm system develops,” Chad Myers, CNN Meteorologist said. “Significant severe weather will occur in the warm air across the South and a major snow and ice event will happen in the western Great Lakes and northern Plains.”

For the northern Plains and Midwest, the threat for blizzard conditions is increasing, as significant snow, strong winds, ice and freezing rain will all be possible early next week from Colorado through Wisconsin.

CNN Weather

“A winter storm is expected to impact the Northern Plains Monday night through Thursday,” the National Weather Service office in Bismarck, North Dakota said. “Difficult travel conditions are expected Monday night through Wednesday night from heavy snow, reduced visibility, and drifting snow.”

Heavy snow and strong winds will be the main concerns, but freezing rain and ice are also possible.

If winds are at least 35 mph and visibility is less than one quarter of a mile for at least three hours, it could result in a full-blown blizzard across the region.

Widespread snow accumulations across the northern Plains and Midwest will be 4 to 8 inches, and some locations could pick up in excess of one foot through Friday of next week.

“While some uncertainty persists, confidence is increasing that strong winds and significant snows will produce hazardous impacts across much of the Central/Northern Plains and into the Upper Midwest,” the prediction center said.

Slick roadways and near-whiteout conditions will make travel very difficult if not impossible at times for some of these areas. Power outages will also be possible due to very strong winds.

The threat for severe storms is also increasing across the southern Plains and Gulf Coast region including tornadoes, large hail, and damaging winds.

“While tornadoes in December are relatively uncommon when compared to the springtime, they are often more likely across portions of the Southeast and Lower Mississippi Valley, where there is often a secondary peak in the fall and winter,” Matthew Elliott, a meteorologist at the Storm Prediction Center, told CNN.

CNN Weather

The severe storm potential begins Monday night across Oklahoma and northern Texas, gradually spreading into Arkansas, Louisiana, and Mississippi on Tuesday.

Severe storms will likely continue Tuesday overnight across the Gulf Coast region. Nocturnal tornadoes are more dangerous because many people are asleep and unaware they need to be seeking a safe location.

While the greater tornado threat exists during the day, there is still the possibility for a few rotating storms through the evening hours.

By Wednesday, the greatest threat exists for an area from New Orleans to Panama City, Florida.

“The details regarding the areas most at risk from tornadoes will become clearer as the event approaches and smaller-scale trends become more evident,” Elliott said.

Because the forecast can change it is important to pay attention to developments in the coming days.

Storms cause major tornadoes, flooding around the South

JACKSON, Miss. (AP) — Residents in several towns across Louisiana and Mississippi took cover as tornado sirens blared late Tuesday, and forecasters warned of the threat of strong twisters capable of tracking long distances on the ground as a severe weather outbreak erupted in the Deep South.

There were no immediate reports of severe damage or injuries as multiple tornado warnings were issued starting Tuesday afternoon and continuing into the nighttime hours as heavy thunderstorms rolled from eastern Texas to Georgia and as far north as Indiana. The National Weather Service confirmed that tornados hit the ground in Mississippi on Tuesday evening and Alabama was in the forecast path of the storms during the overnight hours.

More than 25 million people were at risk as the vast storm system. The national Storm Prediction Center said in its storm outlook that affected cities could include New Orleans; Memphis and Nashville in Tennessee; and Birmingham, Alabama.

The NWS received reports of people trapped at a grocery store in Caledonia, Mississippi, just after 6 p.m. Lowndes County Emergency Management Agency Director Cindy Lawrence told WTVA-TV the people inside the grocery store made it out safely. Lawrence also said a family trapped in a house about a mile (1.6 kilometers) from the store escaped.

Additional reports of property damage near Columbus were received by the NWS, according to Lance Perrilloux, a forecaster with the agency.

Heavy rain and hail as big as tennis balls were also possible as forecasters said the weather outbreak was expected to continue into Wednesday.

In west Alabama, a suspected tornado damaged numerous homes in Hale County, according to storm damage reports to the National Weather Service. About 29,000 customers were without power early Wednesday morning.

And in the west Alabama town of Eutaw, video from WBMA-TV from showed large sections of the roof missing from an apartment complex, where residents stood outside in the middle of the night.

“We’ve got power lines, trees just all over the road,” Eutaw Police Chief Tommy Johnson told WBRC-TV. “In the morning when we get a little daylight, we’re going to do a door-by-door search to make sure no one is trapped inside or anything like that.”

So far, though, there were no reports of injuries. “We haven’t got any reports of anyone hurt or anything,” he said.

Craig Ceecee, a meteorologist at Mississippi State University, peered out at “incredibly black” skies through the door of a tornado shelter in Starkville. He estimated that about 100 people had already arrived as a lightning storm persisted outside.

The Oktibbeha County Emergency Management agency is operating the shelter, about three miles (5 kilometers) from the university’s campus. Ceecee said the dome-shaped multipurpose facility capable of withstanding 250 mph (400 kph) winds.

Before Tuesday’s storm, Ceecee built a database of Mississippi tornado shelters. He said there are several towns without any.

“I’ve had to go through events without (shelters), and trust me, they were scary,” Ceecee said.

In the small town of Tchula, Mississippi, hail stones crashed against the windows of City Hall, as the mayor and other residents took cover during a tornado warning. “It was hitting against the window, and you could tell that it was nice-sized balls of it,” Mayor Ann Polk said after the storm passed.

It’s rare that federal forecasters warn of major tornadoes with the potential for carving damages across long distances, as they did in Tuesday’s forecasts. Tornado watches covering much of Louisiana and Mississippi were announced due to “a particularly dangerous situation,” the NWS said.

“Supercells are expected to develop this afternoon and track northeastward across much of northeast Louisiana and central Mississippi,” the weather service said. “Parameters appear favorable for strong and long-tracked tornadoes this afternoon and early evening.”

The most intense wave of the storm was projected to move through Mississippi between 5 p.m. and 8 p.m., said Sarah Sickles, an NWS forecaster in Jackson, the state capital.

“Multiple rounds of severe thunderstorms — some capable of long-tracked tornadoes with EF3+ damage potential — will be possible this afternoon into tonight over parts of the lower Mississippi Valley region and Mid-South,” the Norman, Oklahoma-based Storm Prediction Center said.

Tornadoes with an EF3 rating on the Enhanced Fujita tornado scale can produce wind gusts of up to 165 mph (266 kph).

All remaining classes at Mississippi State University’s main campus in Starkville switched to remote instruction Tuesday due to the weather. A Mississippi State women’s basketball game against the University of Louisiana-Monroe was to be played on campus, but the venue was closed to spectators. Alcorn State University and the University of Southern Mississippi Hattiesburg were closing early.

Some of Mississippi’s public school systems also closed early.

Flood watches were issued for parts of southeast Mississippi and southwest Alabama, where 3 to 5 inches of rain (8 to 13 centimeters) could lead to flash flooding, the National Weather Service said.

Meanwhile, heavy snow was snarling traffic in some parts of the Upper Midwest.

Minneapolis-St. Paul International Airport tweeted Tuesday afternoon that its runways were closed due to fast snowfall rates and reduced visibility. Air traffic websites showed some inbound planes circling or diverting to other airports such as St. Cloud, Minnesota, and Fargo, North Dakota. The National Weather Service reported nearly 4 inches (10) of snow on the ground at the airport by noon.

Tornadoes: At least 1 dead, multiple people missing in Oklahoma after more than a dozen tornadoes hit 3 states, officials say



CNN
 — 

At least one person was killed and multiple people are missing after tornadoes hit Oklahoma, Texas and Arkansas late Friday, damaging homes and knocking out power for thousands as officials launch search and rescue efforts.

The person who died was in McCurtain County in southeastern Oklahoma, which suffered significant storm damage after a possible tornado hit the city of Idabel, county emergency manager Cody McDaniel said.

Late Friday, authorities were trying to determine the extent of damages and injuries, McDaniel said, adding, “It’s not good.”

In Texas near the state’s border with Oklahoma, at least 50 homes were damaged or destroyed in Lamar County as of Friday evening, the sheriff’s office said.

Multiple tornado warnings were in effect in Texas, Oklahoma, Arkansas and Missouri Friday night, meaning tornadoes were reported to be on the ground or indicated by weather radar. The weather service recommends residents in warning areas to move to a safe like a basement or interior room.

A preliminary accounting Friday evening from the National Weather Service Storm Prediction Center shows nine tornadoes formed in Texas, four in Arkansas and one in Oklahoma.

Overnight tornadoes can be particularly dangerous because they can be hard to see as they move quickly through an area, and it’s also more challenging to ensure residents are warned during those hours.

Plus, more than 90,000 homes and businesses were without power across Arkansas, Louisiana, southeastern Oklahoma and eastern Texas as of early Saturday, according to Poweroutage.us.

Most of the Texas tornadoes reported occurred along the Red River border with Oklahoma, with widespread damage reported in two counties.

The National Weather Service confirmed late Friday that a tornado moving 45 mph was detected over the city of Wrightsville in Pulaski County, Arkansas, just south of Little Rock.

The number of tornadoes recorded will likely increase Saturday, and the intensity of each one will not be known until local National Weather Service offices conduct damage surveys, which may take several days.

Tornado and severe thunderstorm watches for the region lasted until early Saturday morning.

Lamar County officials declared a disaster after at least 10 people were injured when a tornado tore through the area, according to a news release from the county’s sheriff’s office. No deaths have been reported.

Two of those injured suffered critical injuries, the sheriff’s office said. Earlier Friday, a first responder was injured during the storms in the county and underwent surgery, County Constable Steven Hill told CNN.

“There has been quite a bit of damage and some injuries,” Lamar County Constable Travis Rhodes told CNN Friday night.

In nearby Hopkins County, at least four houses were damaged Friday, according to the county’s sheriff’s office.

A woman in Choctaw County, Oklahoma, was injured by a falling tree as she was trying to get to a storm shelter, Lewis Collins, a volunteer at the Choctaw Office of Emergency Management, told CNN. It’s unclear whether a tornado had occurred in that area.

Oklahoma Gov. Kevin Stitt said he’s praying for those impacted by the tornadoes.

“Search & rescue teams and generators forwarded to the Idabel area,” he sad. “Storms hit in Bryan, Choctaw, and Le Flore counties, among others. Additional flash flooding in some areas.”

The Oklahoma Department of Emergency Management and Homeland Security is urging residents to report storm damage online to help coordinate their response.

At least 1 dead as tornadoes tear through Oklahoma, Arkansas and northeast Texas



CNN
 — 

An early winter blast met record autumn warmth Friday, leading to a robust, severe storm system in the South and creating the biggest tornado threat the US has seen in more than five months.

At least one person is dead in McCurtain County, Oklahoma, where significant storm damage was reported, according to county emergency manager Cody McDaniel.

Nine twisters formed in Texas, four in Arkansas, and one in Oklahoma, a preliminary count by the National Weather Service’s Storm Prediction Center shows.

The total number will likely increase in the light of day Saturday, and the intensity of each one will not be known until local NWS offices conduct damage surveys, which may take several days.

In Texas, damage was confirmed west of Paris and near Sulphur Springs in the state’s northeast.

As the system moves east, a tornado watch is in effect Friday evening until midnight for parts of Arkansas, Louisiana, Oklahoma and Texas.

At least four houses were damaged in Hopkins County, Texas, by a tornado, the sheriff’s office there said. No injuries were reported.

In neighboring Lamar County, where Paris is the county seat, “there has been quite a bit of damage and some injuries,” Lamar County Constable Travis Rhodes told CNN Friday night.

In Oklahoma, a woman was injured by a falling tree as she was heading to a storm shelter, Lewis Collins, a volunteer at the Choctaw Office of Emergency Management, told CNN. It’s unclear whether a tornado went through the area, he said.

The Storm Prediction Center had highlighted a ‘moderate risk’ – a Level 4 of 5 – area of severe thunderstorms on Friday for eastern Texas, southeastern Oklahoma, southwestern Arkansas and northwestern Louisiana.

The Dallas-Fort Worth metropolitan area remains under an enhanced risk – a Level 3 out of 4 – for Friday.

“The most likely area for strong tornadoes [EF2 or higher] will be from far southeast Oklahoma southward into eastern Texas, to the east of the I-35 corridor,” the prediction center said.

The watch in effect until midnight includes portions of western and central Arkansas, northwest Louisiana, southeast Oklahoma, and east and northeast Texas, according to the Storm Prediction Center.

In addition to intense tornadoes, scattered large to very large hail, bigger than golf ball-sized (2 inches in diameter), are also possible, according to the Storm Prediction Center.

The main threat will shift from tornadoes Friday afternoon and evening to damaging winds going into the overnight hours as thunderstorms align and spread into Arkansas and Louisiana.

As the storms push east, a significant widespread and damaging wind event is forecast later Friday evening across portions of the Ark-La-Tex region. That is why the prediction center has upgraded the threat level for Friday.

“Storms will persist well into the night, tracking across much of Louisiana and Arkansas, and into western Mississippi, the prediction center added.

This storm system will be moving quickly from west to east, which will minimize the chance for flash flooding to occur across the Ark-La-Tex region. Farther north, rainfall of one to four inches is expected through Saturday over a broad area from Kansas to Wisconsin.

Rainfall is much needed in this region as recent drought has cause the Mississippi River to reach record low levels, impacting shipping and the supply chain.

In all, 42 million people from Texas to Wisconsin were at risk of severe storms Friday. Houston, San Antonio, Oklahoma City, Little Rock, Kansas City and Wichita are included in the risk areas as well.

The last time the greater Dallas-Fort Worth area was under an enhanced risk or higher was May 24.

While tornadoes in the US can happen in any month of the year, they are most common in the spring time thanks to the clash of cold and hot air as the seasons change. The same merging of temperatures also occurs in the autumn, which is why you will often see a secondary “severe season” later in the year.

“You can see that while the spring months are our busiest time climatologically, there is a secondary increase in tornado activity in November,” the National Weather Service in New Orleans said.

Texas sees the most tornadoes (7) in the month of November on average, followed by Alabama (6), Louisiana (5), and Mississippi (5).

The time of day when a tornado occurs makes a big difference in the fatality rate. Nocturnal tornadoes are more dangerous because many people are asleep and unaware they need to be seeking a safe location. While the greater tornado threat for this particular event exists during the daytime hours, there is still the possibility for a few rotating storms through the evening hours.

Make sure you have your severe weather safety plan ready to go before bad weather hits. Know where you will go if severe weather hits, and make sure flashlights work and cell phones are fully charged in case you lose power.

“One of the most important features of your severe weather safety plans is to have a reliable means to receive severe weather warnings,” the weather service in New Orleans said.

Tracking storms, some with severe potential, today in Metro Detroit: What to expect

DETROITWelcome to Monday!

We have a marginal risk for severe storms later this afternoon, and it all depends on how the rest of today sets up here around Metro Detroit.

A weak disturbance moving our way overnight is still bringing a few rain and thundershowers early this morning, and it may slow you down for that Monday morning commute. These showers won’t last too long and should be moving out by 8 a.m. as we try to clear out. We may be in for more trouble if the skies do clear out this morning and into the afternoon.

It’s partly cloudy early this morning with temperatures starting in the upper 60s to lower 70s.

Today’s sunrise was at 6:56 a.m.

We may see scattered strong-to-severe storms later today due to the heat and humidity building in Metro Detroit, creating an unstable atmosphere.

High temperatures will at least hit the middle 80s, with a chance of landing near 90 degrees, if we hang on to that hazy heat. A warming wind will move SW at 7-17 mph, gusting to 20-25 mph, at times.

A line of storms will be most likely after 4 p.m. today, moving in a line from west to east. These storms will produce some heavy downpours in no time, so watch out for pooling and ponding as we slow it down for the evening drive. A few storms also could produce gusty winds over 50 mph, which is capable of creating some damage. And there’s the deadly threat of lightning later this afternoon into the early evening.

There is a chance that the storm line slows down and delivers these storms later in the evening and overnight. We must be on guard for some storms late tonight and early Tuesday, but the storms tend to lose much of their severe strength without the heat of the day.

Here is the weather forecast for Metro Detroit.

Storms Tuesday morning

Showers and storms will be possible through about 7 a.m. Tuesday before we start to see much different weather moving. Tomorrow, we’ll see some sunshine in the afternoon with highs in the low-to-mid 80s. Winds will move WSW at 7-17 mph, gusting to 20-25 mph at times.

Milder rest of the week

We will see sunshine mixed with a few clouds on Wednesday on a very pleasant day to get over the hump. Highs will settle in the lower 80s with low humidity and a nice breeze moving WNW at 8-18 mph, gusting to 20-30 mph.

Thursday will be almost identical with morning lows in the 50s and afternoon highs cooling just a bit into the middle 70s as an early fall-like feel.

Friday will have more dry weather with sun and clouds and highs closer to 80 degrees.

Maybe rain this weekend

The weekend ahead is far enough away to have more of a “wait and see” mentality.

The computer models are hinting at a dry day Saturday with increasing clouds and highs in the lower 80s. Sunday will become a little muggier with scattered showers and storms possible in the afternoon. We will keep you posted as we get closer.
