San Francisco Bay Area storm live updates: Southbound lanes of Hwy 1 reopen after rockslide near Tom Lantos Tunnels

SAN FRANCISCO (KGO) — Intense storms that battered the San Francisco Bay Area for more than a week caused flooding, downed trees and power outages. After another weekend of rain and strong winds, some dry days are ahead this week, but another storm is expected Wednesday. Even with a break in the rain for now, the region is still facing residual effects as a result of the strong storm.

People head outside to enjoy the sunshine for 1st time in weeks as storm cleanup continues

After a seemingly never-ending stretch of storms, the sunshine is finally back in the Bay Area.

In San Francisco, a still soaked Crissy Field was alive with people.

“We didn’t have to bring our umbrella. We just kind of walked out of the house and didn’t have to worry about getting drenched,” said Kate Costello.

But it wasn’t bright skies for everyone. Earlier in the day, The Golden Gate National Recreation Area tweeted a photo of an old military structure on the beach of Fort Funston after it slid down a nearby bluff.

“I believe that what rolled out of the hill this morning was a piece of the rifle range, apparently dated to the 1930s,” said retired National Park Service Curator, John Martini.

The structure tumbled off the cliff around 10 a.m. Monday, likely due to the saturated land according to park officials.

“We actually did a study to see could we stabilize in place some of these structures, especially some of the gun positions, and it was just so prohibitively expensive,” said Martini.

Fort Funston is home to several such military structures, some of which played roles during the second world war.

Due to time and erosion, several have fallen over the years.

No one was injured in the slide, but park staff reminded visitors to be cautious of their surroundings in the area.

South Bay reservoirs spilling following storms

This series of atmospheric storms filled many Santa Clara County reservoirs to the point of spilling.

“Uvas Reservoir in South County has been spilling for a good week, Almaden Reservoir on and off, Coyote Reservoir been spilling,” said Bassam Kassab, Water Supply Operation Manager for Valley Water.

The most recent to spill has been Lexington Reservoir near Los Gatos.

Crews have been working to clear debris and blockage throughout the county but one of the most important jobs for those who manage the local waterways will be to draw down the reservoirs to stop the spilling.

They expect spilling at Lexington to stop in the next three days and the other reservoirs within a week or two.

This time of year, Valley Water says the reservoirs can’t stay completely full in case more storms come, so they will be releasing some of the water until the spring when we typically don’t expect as much rain.

Newsom also says “the dryers are getting a lot drier in the last three years and the wets are getting a lot wetter. This weather Whiplash is that new reality?”

He says the focus should be on how the state manages these challenges and how it deals with hydrology going forward. “In terms of storm water capture, rainwater capture, and how we address these floods in terms of banking the water for the future.”

    Bay Area Level 3 storm: From downed trees to flood threats, here’s a look at storm damage around the region

    SAN FRANCISCO (KGO) — ABC7 News is already seeing storm damage across the San Francisco Bay Area due to a dangerous atmospheric river moving through the region.

    Here’s a look at where there are reports of downed powerlines, landslide threats and toppled trees due to a Level 3 storm on the exclusive ABC7 Storm Impact Scale:

    LIVE UPDATES: Newsom issues State of Emergency for CA to help with storm response

    East Bay

    Residents of 15 homes in Richmond voluntarily evacuated Tuesday night and Wednesday after the hillside above the Seacliff development began showing signs of mudslides.

    Mayor Tom Butt said in his e-forum newsletter Wednesday that arrangements were made for residents without places to go to stay in an Emeryville hotel. Butt said Seacliff Drive was closed between Seacliff Way and Canal Boulevard, while Seaview Drive and Seacliff Way from Seacliff Drive to Admiralty Way were also closed.

    Butt said a geologist was on site Wednesday morning, as well as a local contractor working on mitigating the damage.

    Richmond Police Sgt. Donald Patchin said there’s no estimate as to when people can get back to their homes.

    “It’s just a waiting game right now, with this atmospheric river coming in over the next few days,” Patchin said.

    San Ramon police wrote on Twitter Wednesday morning that Crow Canyon Road is closed in both directions west of city limits toward Castro Valley due to a threat of landslides.

    There is limited access for residents only, police said late Wednesday morning.

    Police said the road was closed by the Alameda County Public Works Agency due to debris and unsafe road conditions.

    In El Cerrito, large tree came down at around 5:30 p.m. The homeowner told us she has no electricity and PG&E won’t be able to reconnected that power until the tree is cleaned up.

    Another tree came down on a home in Richmond. A homeowner was inside, she is okay but tree actually pierced through the roof and came into her son’s bedroom.

    Around 6 p.m., a tree came down along the Richmond Parkway. Traffic in both directions was blocked but tree crews were able to pull the tree to the side and open traffic a couple hours later.

    City officials in Oakland have joined numerous municipalities around the Bay Area in declaring a local state of emergency Wednesday due to the winter storm still pummeling the region.

    The emergency declaration allows the city to call in any and all staff to respond to emergency conditions as they occur overnight. The city’s public works, transportation, fire and police departments have all staffed up to manage increased service needs, according to the announcement.

    The fire department’s crisis responders have been working with unhoused residents to inform them of shelter options and coordinating transportation for those who need it. In addition, the Ira Jinkins Center — at 9175 Edes Ave. near the Coliseum — will be providing three free meals on Thursday as well as providing emergency shelter to all ages and families.

    The city’s year-round shelter at St. Vincent de Paul, located at 675 23rd Street in West Oakland, has doubled their bed capacity to serve the homeless through Friday morning enabling them to shelter up to 100 people.

    For residents who need a temporary refuge from the wet weather, or for those experiencing a power outage, all 18 public library locations are open and have power. Thursday hours are 10 a.m.-5:30 p.m. and the main library is open until 8 p.m.

    For the latest information on Oakland’s winter storm updates, see oaklandca.gov/topics/winter-storms.

    North Bay

    Sonoma County officials are concerned about potential flooding as this storm intensifies, issuing an evacuation warning for any residents living near the Russian River floodway between Healdsburg to Jenner.

    This comes as power has been out for most of Guerneville since Wednesday night.

    “We’re going to get hit, I haven’t seen this since 2019,” Karen Devan, a Guerneville resident said.

    Just shy of four years ago, most of Guerneville was underwater the last time the Russian River flooded back in February 2019.

    It was so serious, there was no way in or out of the city except by watercraft.

    Karen Devan, her partner and their dog Fergus not taking any chances, after living through the last flood.

    “Safeway will flood, drugstores will close, basic necessities will close down and the fire department will be awfully busy doing rescues, so you’re kind of on your own to figure it out,” she said.

    Deciding to book a hotel for the next two nights in Santa Rosa after losing power Wednesday night.

    Meanwhile, businesses bracing for history to repeat itself, lining sandbags across their front doors and closing up shop to get out of dodge.

    San Francisco

    Yellow caution tape near Chrissy Field’s warming hut in San Francisco didn’t stop some people from crossing to get a better look at waves crashing into the shore near the Golden Gate Bridge. Some minor flooding carried debris, including rocks, sticks and garbage into a path normally accessible by pedestrians.

    As rain came down Thursday afternoon the Marina was mostly quiet with light traffic and just a few people outside. The East Beach at Chrissy Beach, a spot typically popular for dogs and their owners even on a weekday, was fairly desolate. Waves wiped out much of the beach with water coming farther up than it typically does.

    San Francisco Public Works crews were out all night to clear downed trees, drain flooded intersections and clear blocked walkways after Wednesday’s billowing winds and drenching rainfall.

    A spokesperson from the city’s emergency operations center said Thursday that there has been 445 incidents of fallen trees and branches around San Francisco in the last week, with 286 of those being reported in the last 24 hours.

    Crews have worked continuously to clear storm-related threats to the public, like sink holes, downed power lines, flooded areas and blocked passageways.

    Emergency operations officials remind residents that sandbags are still available at the Public Works’ operations yard at Kansas and Marin streets until 8 p.m., or until supplies runs out. Each household or storefront can receive five sandbags

    On Wednesday, ABC7 News reporter Lyanne Melendez said glass was falling from two broken windows at the Fox Plaza Building, forcing the closure of a part of Market and Polk.

    South Bay

    After 17,000 customers were without power early Wednesday morning, PG&E restored energy to much of the San Jose area. Still, dozens of stoplights were out throughout the downtown area for much of the day indicating outages throughout.

    The rain wasn’t much of the cause of the issues, but the wind certainly was. In fact, the wind knocked a large tree branch down, ripping power lines down with it. Neighbors described it sounded like an earthquake when the branch fell. Thankfully no injuries were reported and San Jose Fire and PG&E cleared the area quickly.

    RELATED: More than 25K customers without power, PG&E says

    The Santa Cruz County coastline has taken a serious beating from the most recent atmospheric river storm.

    Tweets from the county’s official Twitter account show “significant damage” to Capitola and Seacliff piers.

    The county announced Thursday morning that the coast was extraordinarily dangerous because of high tides and enormous waves.

    People should avoid all bodies of water while coastal areas are under a flood warning by the National Weather Service until 4 p.m. Thursday.

    Multiple road closures are also in effect throughout Santa Cruz County due to flooding.

    Peninsula

    After the heavy rain caused Belmont creek to overflow last weekend, Belmont officials have closed multiple city streets as a preventative measure ahead of the worse part of the storm. Business owners in the area say they as ready as they can be.

    San Mateo County Public Works Department has used 275 tons of sand and over 18,000 sandbags so far Wednesday, but at this point there is shortage of both supplies. We’ve seen people bringing their garbage bags hoping that can help them prevent flooding to their property.

    New Year’s Eve storm 2nd wettest day on record for San Francisco

    SAN FRANCISCO (KGO) — San Francisco was THIS close to breaking a record for the single-wettest day in the city’s history.

    The Bay Area was hit with a Level 2 storm according to ABC7’s exclusive Storm Impact Scale on New Year’s Eve on Saturday.

    ABC7 News meteorologist Drew Tuma tweeted December was the wettest month all year at 4.76″. He says the city saw 31 days worth of December rain fall in only 13 hours—from midnight to 1 p.m. Saturday.

    As of 3p.m. on Satruday, a rain gauge recorded downtown San Francisco at 5.33 inches. It was inching close to beating a record of 5.54″ in a single day back on Nov. 5, 1994, according to the National Weather Service. That’s 28 years ago.

    Tuma says the NWS records go back to 1849.

    So was Dec. 31, 2022, the last day of the year, the single-wettest calendar day on record in San Francisco?

    No, but it was close.

    Rain measured at 5.46″ in downtown San Francisco, according to the National Weather Service.

    But it did become the second rainiest single day surpassing a record from Jan. 29, 1881—which measured at 4.67″—142 years ago.

    San Diego to See Rain Christmas Week From Atomospheric River – NBC 7 San Diego

    We may not be getting a White Christmas this year, San Diego, but it will certainly be wet.

    Back-to-back storm systems — one fueled by an atmospheric river — will bring rain, gusty winds, chilly temperatures and potentially some light mountain snow to San Diego County this week.

    While California comrades to our north saw stormy weather starting as early as Tuesday, the first storm system is expected to reach San Diego County on Thursday.

    The second system, a much less powerful one, will move in on Christmas Day.

    From Thursday to at least Saturday, “there’s going to be occasional waves of rain making their way through San Diego,” said NBC 7 Meteorologist Brian James.

    “Looks like the rain will start Thursday afternoon with the bulk of the rain continuing through the day Friday,” James said. “We’ll probably have some rain taper off as we go through the day on Saturday, but still some showers on the way for Saturday as well.”

    The heaviest rainfall will impact San Diego County overnight Thursday into Friday, when the storm fueled by an atmospheric river reaches the region, according to forecasters.

    Some parts of the county could receive more than two inches of rain from this storm system alone, the National Weather Service predicted. The mountains could see up to five inches of rainfall.

    As for snow, don’t expect much. The areas most impacted will be above 6,500 feet — which we don’t have many of in San Diego — and maybe down to 5,500 feet during the second, lighter storm.

    The biggest impacts could come in the form of flash floods and gusty winds that have the potential to down tree limbs or power lines.

    So far, no watches or warnings have been issued but it’s likely they’ll come.

    What is an atmospheric river?

    An atmospheric river is a portion of the atmosphere that pulls moisture into a type of stream invisible to the naked eye. There are typically about 11 above Earth at any given moment.

    Those streams, made up of condensed water vapor, not water, move from the tropical regions near the equator towards the poles.

    Each atmospheric river can measure anywhere from 250 to 400 miles wide and can be more than 1,000 miles long, carrying up to 25 times the flow of the Mississippi River, according to NBC 7 Meteorologist Ana Cristina Sánchez.

    While atmospheric rivers typically hover around 10,000 feet above Earth, a weather system — like this week’s storms — can push an atmospheric river towards land, causing heavy downpours.

    Atmospheric rivers, most common during the fall and winter seasons, play a major role in California’s rain season. 25-50% of our state’s annual precipitation is produced by atmospheric rivers. Rain and snow amounts can vary widely depending on the exact location, timing and moisture content.

    How will this storm affect my holiday travel?

    The short answer: you’ll likely be impacted.

    The National Weather Service said hazardous travel is possible, particularly on Wednesday through Friday when rainfall will be at its heaviest across California — and will potentially cause flooding.

    “Flooding and hazardous roadways are the main concern with this storm system. Please plan ahead and use extra time when making those holiday travel plans!” the NWS wrote on Twitter.

    If you do plan to travel during the storm, California’s emergency operator has some tips on what to keep in your emergency car kit — from a flashlight to a hand-crank radio that can pull in weather radio stations. Check out their list here.

    Bomb cyclones, atmospheric rivers, tornadoes and nor’easters: extreme weather strikes the U.S. coast to coast

    In a matter of days, the weather pattern has shifted from weeks of calm to one of the most dynamic fall patterns in memory. And while autumn is known for its wild swings, the pattern right now is literally off the charts, with the Northeast Pacific experiencing both its strongest and third-strongest storms on record in a matter of just 72 hours.

    On Sunday, a wicked atmospheric river unleashed more than a foot of rain in parts of California, while a separate system spawned numerous strong tornadoes on Sunday night in the nation’s middle. That same system will become yet another bomb cyclone — with hurricane-force wind gusts possible — for the Northeast coast on Tuesday.

    All three of these systems have amazed meteorologists and, not surprisingly, are consistent with what climate scientists expect from a warming planet.

    Powerful atmospheric river

    After months of one of the driest stretches ever observed in the West, capping off the worst drought in modern history, the Pacific jet stream came alive this past week and dove to the south, following a general cooling of the waters in the Northeast Pacific.

    Last week the powerful jet stream raced across the Pacific Ocean, eventually spinning off a storm system which ended up becoming the third most intense low pressure on record in the Northeast Pacific.

    CBS News


    But that turned out to be just a warm-up. This past weekend, a wicked 200 mph Pacific jet stream helped fuel another storm on Sunday, this time even stronger. The pressure dropped to 942 millibars — the equivalent of a borderline Category 3 to 4 hurricane — and became the most intense cyclone on record in the Northeast Pacific.

    CBS News


    A strong jet stream alone does not always materialize into extreme weather. In order for that to happen a process called cyclogenesis needs to occur. Cyclogenesis is the process of a storm forming. It essentially takes the linear energy of a narrow band of intense upper level winds called a jet stream and converts that straight wind into a broad spinning wind, or circulation, like the two images above.

    But the wind doesn’t just circulate. It needs a mechanism in the atmosphere to force it to spin and in the case of the past few days that force was provided by a strong atmospheric block — a mountain of warm air — over northern Canada. The jet stream could not go through that block, so the wind was forced to divert, going around the block, which initiated rapid spinning and storms with record-breaking low pressure.

    This process of storm formation is a natural occurrence, but it can be argued that climate change helped make these systems more intense. That’s because high-latitude blocking is theorized to be more common in a warming climate, and stronger blocks can lead to stronger cyclogenesis.

    Sunday’s record-setting Pacific storm helped slingshot an extremely focused atmospheric river of tropical moisture into California. It was rated a Category 5 out of 5.

    CBS News


    This storm produced up to 17 inches of rain in central-northern California and broke the all-time record for 24-hour rainfall in Sacramento — a rainfall event so heavy it was likely a once-in-100-year event.

    The torrential rain was heavy enough to effectively end what was a very active wildfire season across the northern half of California and even put a small dent into what, up until this point, had become the worst western U.S. drought in modern history.

    October 21, 2021

    CBS News


    While it may seem odd for the weather pattern to switch from extremely dry to extremely wet in an instant, this is a natural characteristic of the Mediterranean climate of the West Coast. However, there is evidence that climate change is making these episodes of weather whiplash more common now, and the climate models indicate that trend will continue into the future.

    CBS News


    Midwest tornado outbreak

    At the same time the West was being pounded by a wicked atmospheric river, another storm was moving through the Midwest. While the event was well forecast to produce severe weather and even tornadoes, the ferocity of the storms was somewhat unexpected.

    There were several Tornado Emergencies issued by the National Weather Service and in total 15 tornado reports in Missouri and southern Illinois.

    CBS News


    On Monday, the storm damage was still being surveyed, but the damage was extensive from winds up to 150 mph.

    As the climate has warmed, there has been no clear trend in the number of tornadoes in recent decades. But one trend has emerged as a significant shift: Tornado frequency is increasing east of the Mississippi River over the Mid-South and decreasing over the area traditionally known as Tornado Alley in the lower Plains. This has meant tornadoes happening in more densely populated areas, most often at night — as they did Sunday night — which makes the storms all the more dangerous.

    Gensini et al.


    Nor’easter “bomb cyclone”

    The storm responsible for the outbreak of tornadoes in the nation’s midsection is now moving east. Just like the Pacific storm, this system will slow, bend and be forced to circulate more intensely by the Canadian blocking. Thus, what happened in the eastern Pacific will replicate itself along the East Coast, just not quite as strongly.

    Heavy rain will move from the Ohio Valley into the Northeast Monday night and Tuesday as a coastal storm rapidly intensifies east of New Jersey. By Tuesday afternoon, the storm’s barometric pressure will drop down to the equivalent of a Category 2 hurricane.

    CBS News


    Storms that exhibit rapid pressure drops often overperform in terms of wind gusts. Eastern Long Island and southeast New England will see gusts over 60 mph, with some potential for wind gusts over hurricane force (75 mph+). With leaves still on the trees and very heavy rain softening up the ground, the potential for downed trees and power lines, and well as power outages, are possible, especially along the coast.

    With a prolonged onshore flow, coastal areas prone to flooding should expect at least minor flooding issues at times of high tides. The storm will wind down on Wednesday morning, having dropped 3 to 5 inches of rain in its wake, adding to what has been one a very wet year for the major cities of the Northeast.  

    While there has not been much research on changes to the intensity of nor’easters due to climate change, the science shows that rain rates and rain totals will continue to increase due to both a warmer atmosphere and warm ocean.

    Typically, the energy release from higher rainfall rates can feedback into more intense cyclones. It stands to reason that a warmer ocean will result in more intense storms. As seen in the graphic below, sea surface temperatures off the Northeast coast are 5 to 10 degrees Fahrenheit above normal. This is not a temporary shift — it is systemic. Research has found that regions like the Gulf of Maine are warming faster than 99% of the oceans.
