As ice storm continues in the South, the Northeast braces for dangerously frigid temperatures

As tens of thousands remain without power in Texas on Thursday amid frigid temperatures and icy roads, the Northeast is bracing for a blast of bitterly cold air that could feel well below freezing.

Texas has been bearing the brunt of a dangerous ice storm that dumped several rounds of sleet and freezing rain, causing life-threatening road conditions in surrounding states including Oklahoma, Arkansas and the Memphis area in Tennessee.

On Wednesday, Texas reported a third person had died during the storm after losing control of her truck on an icy road north of Eldorado. One person was killed in Austin in a 10-car pileup, and another person died after their car rolled over in the Dallas-area city of Arlington, officials said.

And while Thursday is expected to bring some relief from the deadly storm as temperatures slowly rise, the piling of multiple layers of ice and sleet has snapped tree branches and limbs and led to power outages for more than 360,000 homes and businesses in Texas. That means thousands of people likely don’t have proper heating or hot water as ice coats the ground.

Overnight into early Thursday, an additional quarter inch of ice could possibly glaze already slippery roads, particularly in central and northern Texas, southern Oklahoma and Arkansas.

“This will bring storm total ice accretions to over 0.5” for many locations which will raise the risk for significant tree damage and power outages, in addition to icy, dangerous roads. Sleet may also mix in at times with the freezing rain which will increase the chances for icing on the roadways,” the National Weather Service said.

By late Thursday night, the Northeast could begin feeling temperatures below zero from a separate winter storm, prompting officials in several states to announce preparations.

In Connecticut, the governor activated the state’s severe cold weather protocol beginning noon Thursday through the weekend.

“With the kind of severe cold weather that is headed our way, frostbite can develop on exposed skin in under 30 minutes. Spending long periods of time outdoors in these conditions is not only harmful, it can be fatal,” Gov. Ned Lamont said.

The governor added that shelters and warming centers are available across Connecticut, and transportation can be provided when needed.

Similarly, warming centers are expected to be available in Maine, Rhode Island, Massachusetts and Vermont, officials said.

In Boston, the mayor declared a cold emergency in the city for Friday through Sunday ahead of the severely cold weather.

“I urge all Boston residents to take precautions, stay warm and safe, and check on your neighbors during this cold emergency,” Mayor Michelle Wu said.

More than 15 million people are expected to be under a wind chill watch or warning in the Northeast beginning either Thursday night or Friday morning through at least Saturday afternoon.

The National Weather Service issues a wind chill warning when the air is expected to feel -25 degrees Fahrenheit or colder.

The impending wind chill alerts would apply to all of Maine, New Hampshire, Vermont, Massachusetts and Rhode Island, northern Connecticut, much of eastern and central New York and northeast Pennsylvania.

“The air mass descending on the area Friday into Friday night is the coldest air currently in the Northern Hemisphere,” National Weather Service in Caribou, Maine, warned.

The cold air is on a path to move into the Northeast Thursday night and Friday, with the coldest period coming Friday night and Saturday morning, as temperatures fall below zero.

The northern portion of New England will see temperatures drop to 15 to 25 degrees below zero. Plus, the frigid temperatures will be joined by winds of 25 to 40 mph, making air in areas as far south as New York City feel -10 degrees Fahrenheit.

“Avoid any outdoor activities on Friday and Saturday! Cold temperatures paired with the wind chill factor could lead to potentially life-threatening conditions outdoors,” the New Hampshire Homeland Security and Emergency Management said in a post on Facebook Wednesday afternoon.

Meanwhile, northern New York and northern New England will feel like -35 to -50 degrees Fahrenheit with some locations experiencing wind chills as cold as 65 degrees below zero. These extreme conditions can cause frostbite in as little as five minutes.

The cold blast is expected to be brief, with temperatures rising across most of the region by Sunday afternoon.

Winter ice storm: Millions across the South and central US brace as officials urge staying off roads

CNN
—

A winter storm bringing the triple threat of ice, sleet and snow Tuesday to parts of the South and central US has prompted officials to close roads and schools as they urge people to avoid traveling in dangerous conditions.

About 38 million people from Texas and Oklahoma to as far east as Kentucky and West Virginia are under various forms of winter weather alerts, including those warning of dangerous ice accumulations forecast to make roads a nightmare.

“In addition to potentially hazardous travel conditions, this amount of ice will lead to tree damage and power outages across the hardest-hit regions,” the National Weather Service warned in its forecast Monday.

In Texas, residents in cities including Dallas, San Antonio and Austin can expect icy roads as well as some sleet Tuesday, when heavy rain and flash flooding are also possible in the eastern parts of the state.

Amid such conditions, the governor has requested the state’s emergency management division to increase its resources so it can be ready to respond through Thursday.

The storm has also led several school districts in the Dallas-Fort Worth area and Austin to close Tuesday, and more than 400 flights departing from Texas airports have been cancelled. Multiple roadways in Texas have been shut down due to ice accumulation, according to the state’s transportation department.

As ice began forming on roads in Little Rock, Arkansas, the governor declared a state of emergency Monday and activated the winter weather support teams of the state’s National Guard to be prepared in helping police in their response to the storm.

“I encourage Arkansans who are experiencing winter weather to avoid travel if possible and heed the warnings of local officials,” Gov. Sarah Huckabee Sanders said on Twitter.

The emergency order directs $250,000 toward discretionary use by the head of the state’s Division of Emergency Management to provide funding for program and administrative costs, the order stated.

“The real enemy is going to be that ice,” said Dave Parker, a spokesperson for the Arkansas Department of Transportation. “This could potentially be a pretty dangerous situation.”

Parker added that majority of the state is expected to be impacted, and the state is treating most major roads.

By late Monday, ice had already spread across grounds in Memphis, Tennessee, and Louisville, Kentucky, as well as Texas, where at least a few car crashes were reported in Austin with no injuries.

The storm is poised to produce a mix of wintry precipitation ranging from rain and sleet to ice and it will hit areas in the southern and central regions in waves through Wednesday.

And while the forecast shows there will be periods of reprieve over the next two days, roads will likely remain dangerously slick throughout the storm as temperatures remain low.

Indeed, Tuesday is expected to be the toughest day for driving as Texas bridges and roads become icy, according to the weather service’s Fort Worth office.

“More widespread freezing rain/sleet is expected Tuesday and Wednesday morning, with worsening travel impacts during this time,” the local weather agency said.

Significant icing of about half of an inch is expected on roads in Austin, San Angelo and Dallas while San Antonio may see up to a tenth of an inch of ice.

Meantime, Texas’ primary electricity provider, the Electric Reliability Council of Texas, told CNN it will be able to meet residents’ demand as temperatures plummet.

“We expect sufficient generation to meet forecasted demand and are continuing to monitor forecasts, this week. We are not asking for Conservation at this time. We are informing the public that IF they are experience an outage to reach out to their local power provider,” the agency said in an email.

Elsewhere in the South, up to a half of an inch of ice could glaze roads in Memphis, Tennessee. In the state’s Dyer County, icy conditions led officials to shut down the I-155 bridge, according to the highway patrol.

Meanwhile, Little Rock in Arkansas is forecast to see multiple rounds of ice that could amass up to half an inch.

In neighboring Oklahoma, residents in Oklahoma City are under a winter weather advisory through Wednesday afternoon, with the expectation of seeing up to two tenths of an inch of ice.

Icing up to two-tenths of an inch could be seen in Louisville, Kentucky, while Charleston, West Virginia, can see sleet up to an inch and ice up to a tenth of an inch.

From China to Japan, deadly cold is gripping East Asia. Experts say it’s the ‘new norm’

Hong Kong
CNN
—

A deadly cold snap that is gripping East Asia has killed at least four people in Japan after subzero temperatures and heavy snow brought travel chaos during the Lunar New Year holiday, with climate experts warning that such extreme weather events had become the “new norm.”

Japanese officials said all four of those who died on Wednesday and Thursday had been working to clear snow amid what Chief Cabinet Secretary Hirokazu Matsuno has called a “once-in-a-decade cold snap.”

Two of the deaths were reported in the western Niigata prefecture, with one in southwestern Oita prefecture and one in southern Okayama prefecture – where the victim had a heart attack.

In neighboring South Korea, heavy snow warnings were issued this week as temperatures in the capital Seoul fell as low as minus 15 degrees Celsius (5 degrees Fahrenheit) and plummeted to record lows in other cities, officials said. Residents said it began snowing heavily overnight late Wednesday into Thursday.

On the popular tourist island of Jeju, harsh weather this week led to the cancellation of hundreds of flights while passenger ships were forced to stay in port due to huge waves, according to the Central Disaster and Safety Countermeasure Headquarters.

“Cold air from the North Pole has reached South Korea directly,” after traveling through Russia and China, Korea Meteorological Administration spokesperson Woo Jin-kyu told CNN.

Woo said that while scientists took a long-term view of climate change, “we can consider this extreme weather – extremely hot weather in summer and extremely cold weather in winter – as one of the signals of climate change.”

Across the border in Pyongyang, North Korean authorities warned of extreme weather conditions as the cold wave swept through the Korean Peninsula. Temperatures in parts of North Korea were expected to dip below minus 30 degrees Celsius (minus 22 degrees Fahrenheit), state media reported.

In Japan, hundreds of domestic flights were canceled on Tuesday and Wednesday due to heavy snow and strong winds that hampered visibility. Major carriers Japan Airlines and All Nippon Airways canceled a combined total of 229 flights.

Meanwhile, high-speed trains were suspended between the northern Fukushima and Shinjo stations, Japan Railway Group said.

China’s meteorological authority has also forecast big temperature drops in parts of the country and on Monday issued a blue alert for a cold wave – the lowest level in a four-tier warning system.

Mohe, China’s northernmost city, on Sunday saw temperatures drop to minus 53 degrees Celsius (minus 63.4 degrees Fahrenheit) – its coldest ever recorded, meteorologists said. Ice fog – a weather phenomenon that occurs only in extreme cold when water droplets in air remain in liquid form – is also expected in the city this week, local authorities said.

Other parts of Asia also felt the impacts of harsh cold weather.

Earlier this month in Russian Siberia, temperatures in the city of Yakutsk stood at minus 62.7 degrees Celsius (minus 80.9 degrees Fahrenheit) – a record for a place widely known as the world’s coldest city.

The cold was also felt in Afghanistan, where Taliban officials reported the deaths of at least 157 people as the country experiences one of its coldest ever winters with minimal humanitarian aid. Officials said temperatures in early January had plummeted to as low as minus 28 degrees Celsius (minus 18 Fahrenheit).

Yeh Sang-wook, a climate professor at Hanyang University in Seoul, attributed the extreme cold wave on the Korean Peninsula to Arctic winds from Siberia, adding that the cold wave in South Korea this year was partly due to the melting of Arctic ice caps from a warming climate.

“There has been a record melting last year and this year,” he said. “When sea ice is melted, the sea opens up, sending up more vapor into air, leading to more snow in the north.”

As climate change worsens, the region would face more severe cold weather in the future, he said.

“There is no other (explanation),” he said. “Climate change is indeed deepening and there is a consensus among global scientists that this kind of cold phenomenon will worsen going forward.”

Kevin Trenberth, from the US National Center for Atmospheric Research (NCAR), agreed that “extreme weather events are the new norm,” adding, “we certainly can expect that weather extremes are going to be worse than they were before.”

He also pointed to the El Niño and La Niña climate pattern cycles in the Pacific Ocean that affect weather worldwide.

La Niña, which typically has a cooling effect on global temperatures, is one of the reasons for the current cold snap, he said.

“There’s certainly a large natural variability that occurs in the weather but … we often hear about the El Nino phenomenon and at the moment we’re in the La Niña phase. And that certainly influences the kinds of patterns that tend to occur. And so that’s a player as well,” he said.

Another atmospheric river lashes California, renewing flooding concerns in state where storms have left at least 19 dead

January 16, 2023 Admin Leave a comment

CNN
—

Another atmospheric river has arrived in storm-battered California, bringing renewed flooding fears, possible landslides and treacherous travel to the state Monday where a relentless string of storms has already delivered widespread damage and left at least 19 dead in recent weeks.

“We have lost too much – too many people to these storms and in these waters,” Gov. Gavin Newsom said in a statement Saturday, urging residents to prepare for another round of rain.

The latest storm is set to bring heavy mountain snow and periods of heavy rain, with an additional 1 to 3 inches of rainfall expected in areas already too saturated to absorb more water.

Flood watches remain in place for around 8 million people in coastal California, including the Bay Area, until Monday afternoon. A slight risk – level 2 out of 4 – for excessive rain and flooding covers a large chunk of Southern California, including the Los Angeles metro area, until Monday morning then drops to a marginal risk through the day.

Meanwhile, winter storm warnings are posted for the Sierra Nevada where up to 3 feet of new snow could fall through Monday.

Residents of Ventura County’s remote Matilija Canyon were being urged Sunday to leave their homes after more than 17 inches of high-intensity rainfall resulted in significant damage and left towering piles of rock and mud over 40-feet tall blocking some roadways, isolating residents, the Ventura County Sheriff’s Office said, adding that more than ten helicopter flights have carried more than 70 residents from the area.

To the north in San Joaquin County, around 175 residents were voluntarily evacuated from a mobile home park Sunday, including by boat, after flood waters inundated the community, according to the San Joaquin County Sheriff’s Office.

Evacuation warnings were also in place Sunday evening for residents near the Carmel River in Monterey County, on California’s Central Coast. A warning was also in place for residents in Sacramento County’s Wilton area.

“People are fatigued about evacuation orders. People are fatigued by seeing those Caltrans turn signs saying ‘detour’ – they’re just fatigued generally,” Newsom said in a news conference Saturday.

The parade of atmospheric rivers – long, narrow regions in the atmosphere that can carry moisture thousands of miles – turned California communities into lakes, crippled highways and prompted thousands of evacuations.

The good news? A much-needed stretch of dry weather is on the way.

“As we push into the day on Tuesday we’re looking for quieter weather across much of the state with one fast moving additional system arriving for later Wednesday into early Thursday. After that, looking for a period of dry weather for much of the state finally as we head into late week, and pretty much through the weekend,” a National Weather Service spokesman said.

Monday will see the latest round of rain slowly come to an end from Northern California in the early afternoon hours to Southern California later in the day.

But for now, the state is bracing for more flooding, mudslides and rescues. Swift water resources and firefighters have been positioned statewide in preparation for Monday, which could see this round’s heaviest rainfall, state officials said.

Wind gusts reached hurricane-force Sunday across the higher elevations of Southern California, where around 14 million people were under wind advisories into Monday.

And as the latest storm approached, President Joe Biden on Saturday approved California’s request for a disaster declaration, freeing up federal aid to supplement recovery efforts in areas of the state affected by storms, flooding and mudslides since December 27.

The federal assistance can include grants for temporary housing and home repairs, loans to help cover property losses for uninsured homes, according to the White House.

Some isolated higher rain rates of 0.5 inches per hour could lead to a couple instances of flooding, especially given the very wet conditions as atmospheric rivers hammered the state in previous weeks.

Though this weekend’s rainfall totals will be lower than in previous storms, the threshold for flooding is much lower now because the ground is too saturated and conditions are ripe for mudslides and landslides.

There have been 402 landslides recorded statewide since December 30, according to the California Geological Survey.

Rainfall totals in recent weeks have been immense. Already, San Francisco has recorded one of its top 15 wettest winters on record. The Bay Area could see another 1-2 inches by Monday afternoon and the wettest peaks can see up to 3 inches.

To the south, the Los Angeles area saw several locations set daily rainfall records with 1 to 2 inches received Saturday. Southern California may still see isolated areas where heavy rainfall could reach up to a half an inch per hour in the heaviest storms.

Some areas of Santa Cruz County have seen more than 34 inches of rain since December 26, according to county recovery official. If this is to be confirmed by the weather service, it would land Santa Cruz in the top five wettest winters on record – with still a month left to the season.

“We’re getting flooding in our coastal streams, creeks, and rivers,” Santa Cruz County official David Reid said. “And we’re getting extensive landslides and mudslides and road failures in our mountainous areas.”

“There’s definitely a fatigue that happens with the continued storms – folks begin to fear that what we’re telling them isn’t true, but we have real concerns,” Reid added.

The need for residents to follow evacuation orders and adhere to roadway closures is real. Crews around the state have for weeks responded to rescues on flooded streets and inundated neighborhoods.

Storm-related deaths in recent weeks have included a woman whose body was found inside a vehicle that washed into a flooded vineyard, two people who were found with trees on top of their tents, a child who was killed when a redwood tree fell on a home, and several other fatalities.

And in San Luis Obispo County, rescuers are still searching for 5-year-old Kyle Doan, who was pulled from his mother’s hands by rushing floodwater on Monday after their SUV was swept away.

Rains on Saturday hampered the search as water levels rose in the San Marcos Creek and Salinas River, but crews were back out searching for the boy on Sunday as conditions improved, the San Luis Obispo County Sheriff’s Office said.

As lower elevations deal with heavy rainfall, and potential floods and mudslides, those living on higher elevations can expect heavy snowfall and dangerous conditions on the road.

Up to 3 feet of new snow could fall through Monday in Sierra Nevada while mountains in Southern California could see several inches of snow by early Tuesday morning.

Flagstaff, Arizona, saw 14.8 inches on Sunday, shattering a previous record of 8.9 inches set back in 1978.

“Heavy mountain snow and strong winds will lead to blowing snow and whiteout conditions at times, creating dangerous to near impossible travel above 4,000 ft in the mountains and passes of Central California and above 5,000 ft for Southern California,” the National Weather Service said.

Snow could hammer the mountains at a rate of 2 inches per hour at times into Monday morning in the Sierra Nevada, the weather service added.

For Tuesday, the rain and snow will move into the Four Corners Region, but isolated showers and snow showers could still impact parts of Southern California Tuesday morning.

Lower elevations in Arizona, Nevada, Utah and New Mexico can see 1-4 inches of snowfall and the higher elevations can see 1-2 feet.

California weather: Monterey Peninsula could become an island as storms flood swaths of California

January 12, 2023 Admin Leave a comment

CNN
—

Monterey Peninsula residents could soon be living on an island as mammoth flooding threatens to cut them off from the rest of California.

The state has been hammered by a cascade of atmospheric rivers – long, narrow regions in the atmosphere that can carry moisture thousands of miles.

At least 18 people have died, neighborhoods have turned into lakes, and countless homes have been destroyed as a string of storms toppled trees and paralyzed communities over the past two weeks.

California’s flooding, in pictures

But a sliver of good news emerged Thursday: The nearly relentless rainfall has lifted much of California out of “extreme drought” conditions.

And much of the state is getting a brief respite from brutal weather Thursday. But cities are still inundated – and more storms are on the way.

Just south of the San Francisco Bay Area, cities including Monterey, Carmel and Pacific Grove on the Monterey Peninsula could soon be severed from the rest of California due to epic floodwater.

“If anyone was here in 1995, you know that during a large flooding event, the Monterey Peninsula became an island – people were either stuck on one side or the other,” Monterey County Sheriff Tina Nieto warned Wednesday evening.

“And we anticipate that we’re going to go into a similar situation, but not as bad. Some of the roadways are going to be closed, and you could be stuck on one side or the other.”

The sheriff’s office upgraded evacuation warnings to evacuation orders Wednesday in low-lying areas near the Salinas River.

“Monterey Peninsula may become an island again like it did in the ’95 floods, so please start preparing now,” the sheriff warned.

Nieto said it could be days before residents are allowed to return home, as crews need to make sure the area is safe.

According to the Storm Prediction Center, here’s what’s in store for California as another round of storms heads its way:

Thursday: Heavy rain will be confined along the northern California coast and into Oregon and Washington through Thursday night, with a slight risk of excessive rainfall in effect for northwestern California.

Friday: An atmospheric river will likely pummel the northern California and central California coast on Friday. Winter storm watches will likely begin across the Sierra Nevada range.

Heavy snowfall could lead to dangerous mountain travel conditions Friday and Saturday at elevations over 5,000 feet and in the northern and central California passes.

Saturday: A second system will move in on Saturday, and rainfall will spread south and begin to impact the whole state. Excessive rainfall threats will likely be issued for central California.

The recent storms have crippled travel and left dozens of highways inoperable.

At least 40 state routes were closed as of Wednesday night, state transportation spokesman Will Arnold said.

“We’re asking the public: If you don’t need to be on the roadways, please stay home and avoid any non-essential trips,” Arnold said.

Over 100 National Guard members were in San Luis Obispo County searching for missing 5-year-old Kyle Doan after he was swept away from a vehicle surrounded by floodwater on Monday.

Less than 1% of California is now under “extreme drought” – down from one-third of the state just two weeks ago, according to the latest US Drought Monitor report published Thursday.

“Intense precipitation in California the past few weeks – particularly late December and early January – has significantly reduced drought intensity in California,” according to the US Drought Monitor.

In 16 days, swaths of California received 50% to 70% of the amount of precipitation that they would usually get in a whole year, according to the National Weather Service.

Isolated areas, especially in the mountains near Santa Barbara, have recorded more than 90% of their annual precipitation.

But more than 95% of the state still faces some drought designation.

Large portions of the state remain in “moderate” or “severe” drought “since moisture deficits have been entrenched across some areas for the last 2-3 years,” the drought summary said.

The recent rains have “provided a generous boost” to key reservoirs in the state, but most are still below the long-term average for this time of the year.

California storm: 90% of residents are under flood watches as another storm threatens mudslides, power outages and deadly inundation

January 10, 2023 Admin Leave a comment

CNN
—

Much of California can’t soak up another drop of rain. Yet the state is getting pummeled again with torrential downpours and ferocious winds, causing power outages and treacherous travel conditions.

More than 34 million Californians were under a flood watch Monday – about 90% of the state’s population and 10% of the US population.

Parts of the central California coast got walloped with 1 to 1.25 inches of rainfall per hour, the Weather Prediction Center said. Extensive rainfall there Monday triggered significant flooding, mudslides, debris flows and closed roadways.

Widespread rainfall totals of 3 to 6 inches have been observed from just south of San Francisco to just north of Los Angeles. Isolated amounts of 6 to more than 10 inches have been observed in the higher terrain near the coast.

As the rain shifted slowly to the south Monday toward Los Angeles, the National Weather Service there warned of the risk of flooding, debris flow in land scarred by recent wildfires and an increased risk of rock and mudslides in mountains and on canyon roads.

And hurricane-force wind gusts topping 74 mph thrashed states across the western US. More than 37 million people were under wind alerts Monday in California, Nevada, Oregon, Washington, Utah, Arizona and Wyoming.

A 132-mph wind gust lashed Oroville, California. Residents in Washoe City, Nevada, were hit with a 98-mph gust, the Weather Prediction Center said.

TRACK THE STORMS

“Expect widespread power outages, downed trees and difficult driving conditions,” the National Weather Service in Sacramento tweeted. “Now is the time to prepare if you have not already!”

Almost 92,000 homes, businesses and other power customers had no electricity Monday evening, according to PowerOutage.us.

And the central California coast could be at risk of a tornado, CNN Meteorologist Dave Hennen said.

The severe weather is part of a relentless parade of atmospheric rivers slamming the West Coast.

California is now extremely vulnerable to flooding because much of the state has been scarred by historic drought or devastating wildfires – meaning the land can’t soak up much rainfall.

And after an onslaught of storms since late December led to deadly flooding, Gov. Gavin Newsom warned Sunday: “We expect to see the worst of it still in front of us.”

Two bouts of major rainfall are expected to hammer the West Coast over the next few days – without much of a break between events for the water to recede.

The system is part of an atmospheric river – a long, narrow region in the atmosphere that can transport moisture thousands of miles, like a fire hose in the sky.

The atmospheric river slamming California on Monday could result in a 1-in-50 year or 1-in-100 year rainfall event near Fresno, the Weather Prediction Center said.

A moderate risk – level 3 of 4 – of excessive rainfall covers over 26 million people in California, including in San Francisco, Sacramento, Los Angeles and Fresno, where rain could fall at 1 inch per hour.

The San Lorenzo River in Santa Cruz County has risen 14 feet in just over four hours and is in major flood stage. Parts of the county will experience “widespread flooding at shallow depths,” and the city of Santa Cruz will have serious flooding, according to data from the National Oceanic and Atmospheric Administration and US Geological Survey.

The threat will shift further south Tuesday, with a level 3 of 4 risk centered over Los Angeles.

“While some of the forecast rain totals are impressive alone, it is important to note that what really sets this event apart are the antecedent conditions,” the National Weather Service office in San Francisco said.

“Multiple systems over the past week have saturated soil, increased flow in rivers and streams, and truly set the stage for this to become a high impact event.”

In Sacramento County, officials warned “flooding is imminent” and issued evacuation orders for the Wilton community near the Cosumnes River before roads become impassable.

Wilton residents also had to evacuate during last week’s storm, when exit routes flooded quickly, officials said.

El Dorado, Monterey, Santa Cruz and Santa Clara and Alameda counties have issued evacuation warnings or recommendations for some areas due to possible flooding and other safety risks as forecasters warned of swelling rivers.

Residents in all areas of Montecito, the city of Santa Barbara and parts of Carpinteria and Summerland are being ordered to evacuate immediately due to the threat of the ongoing storm, the Santa Barbara County Incident Management Team said on Monday evening.

“LEAVE NOW! This is a rapidly evolving situation,” the team said in a release.

Montecito is a haven for the rich and famous, including Prince Harry and his wife, Meghan, Duchess of Sussex; Oprah Winfrey and Ellen Degeneres. Monday marks exactly five years since heavy rains in the area caused deadly mud- and landslides.

Santa Barbara County authorities are advising residents to “be prepared to sustain yourself and your household for multiple days if you choose not to evacuate, as you may not be able to leave the area and emergency responders may not be able to access your property in the event of road damage, flooding, or a debris flow.”

Newsom on Sunday asked the White House for an emergency declaration to support response and recovery efforts.

“We are in the middle of a deadly barrage of winter storms – and California is using every resource at its disposal to protect lives and limit damage,” Newsom said in a statement. “We are taking the threat from these storms seriously, and want to make sure that Californians stay vigilant as more storms head our way.”

San Francisco Mayor London Breed on Monday issued a Local Proclamation of Emergency due to the ongoing series of winter storms that began New Year’s Eve, according to a news release from his office.

This storm system arrives on the heels of a powerful cyclone that flooded roads, toppled trees and knocked out power last week to much of California. Earlier, a New Year’s weekend storm system produced deadly flooding.

At least 12 Californians have died from “storm-related impacts” such as flooding since late December, the governor’s office said.

In San Luis Obispo County, dive teams from the sheriff’s office and Cal Fire rescuers were searching Monday for a 5-year-old child reported to have been swept away in flood waters near the Salinas River in San Miguel.

“Floods kill more individuals than any other natural disaster,” California Emergency Services Director Nancy Ward said Sunday. “We’ve already had more deaths in this flood storm since December 31 than we had in the last two fire seasons of the highest fire acreage burned in California.”

Flood-related deaths can happen when drivers attempt to cross standing water.

“Just a foot of water and your car’s floating. Half a foot of water, you’re off your feet. Half foot of water, you’re losing control of your vehicle,” Newsom said.

“We’re seeing people go around these detours because they don’t see any obstacles – they think everything is fine, and putting their lives at risk or putting first responders lives at risk.”

For anyone who doesn’t need to travel during the peak of this storm, “please don’t,” California Secretary of Natural Resources Wade Crowfoot said. “Be prepared for power outages and other interruptions. Have those flashlights, the candles, batteries, charge cell phones at the ready.”

Already, flooded roads, toppled trees and downed power lines are making travel difficult, California Highway Patrol said. Some fallen trees crushed cars and homes over the weekend. On Monday, portions of the Pacific Coast Highway – US 101, a major north-south highway, were closed.

The Santa Barbara Airport, a tri-county regional airport, is closed because of flooding airport officials said Monday.

California is experiencing “weather whiplash,” going from intense drought conditions to now contending with its fifth atmospheric river, Newsom said.

Much of the state has already seen 5 to 8 inches of rain over the last week. Two to 4 more inches of rain are expected across the coasts and valleys – and even more in mountains and foothills through Tuesday.

Rising from swelling rivers could spill over and inundate communities.

The rainfall over the weekend brought renewed flood concerns for streams, creeks and rivers. The Colgan Creek, Berryessa Creek, Mark West Creek, Green Valley Creek and the Cosumnes River all have gauges that are either above flood stage or expected to be in the next few days.

“The cumulative effect of successive heavy rainfall events will lead to additional instances of flooding. This includes rapid water rises, mudslides, and the potential for major river flooding,” the National Weather Service said Monday.

The moisture is expected to sink southward Monday night, making flooding “increasing likely” over the Southern California coastal ranges Tuesday, the weather service said. Fierce winds are expected to accompany the storm as it pushes inland.

“Valley areas will likely see gusts as high as 45-50 mph, with gusts greater than 60 mph possible in wind prone areas,” the National Weather Service in Reno said. The Sierra Ridge could receive peak gusts between 130 to 150 mph Monday.

For those at higher elevations, intense snow and ferocious winds will be the biggest concerns.

Parts of the higher elevations in the Sierra Nevada have gotten more than 100” – or 8.3 feet – of snow in just the past few weeks, the Weather Prediction Center said.

Now, another 6 feet of snow is expected in some parts of the Sierra.

As the storm pushes inland, more than 5 feet of snow could fall along the Sierra Crest west of Lake Tahoe, the weather service said.

The heavy snow and strong winds could lead to near whiteout conditions on roads.

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

January 3, 2023 Admin Leave a comment

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.
