    Spillover in Lake Berryessa Reservoir Gushes for First Time Since 2019

    For the first time in six years, water is gushing through a unique spillway in Lake Berryessa, just north of San Francisco.Footage provided to The New York Times showed Lake Berryessa’s spillway overflowed with water.Jay Cuetara, Solano County WaterBack-to-back atmospheric rivers have dumped buckets of rain across Northern California, filling its rivers to the brim and beyond. The Russian River spilled over its banks in Sonoma County, and in the far reaches of the state, Lake Shasta, a key marker of the state’s overall water levels, has nearly filled up.And just east of Napa Valley, a rare not-fully-natural phenomenon was observed for the first time since 2019: Water began gushing, furiously, through a spillway in Lake Berryessa.The eye-catching event has happened only three other times in the past 20 years, and it has drawn curiosity seekers to the man-made reservoir, 70 miles northeast of San Francisco.“People were taking pictures and videos and just standing in awe,” said Peter Kilkus, the editor of the Lake Berryessa News, who was there Wednesday morning with about two dozen other people.The 72-foot-wide spillway, called a morning glory because its shape mimics the flower, is a unique funnel-shaped cement pipe that sits within the reservoir. (Locals call it the glory hole.)The mechanism is a type of drainage system with water pouring down the pipe and into Putah Creek on the other side of Monticello Dam. The spillway is among a few with that shape in the country; there’s also one at Pleasant Hill Lake in Perrysville, Ohio. More

    Expect an Icy Commute for Parts of the Northeast on Monday Morning

    Light snow and freezing rain are expected in parts of Connecticut, New Jersey, New York and Pennsylvania starting Sunday night and could make for a hazardous commute on Monday, forecasters said.A light snowfall and some sleet that will begin on Sunday evening in parts of Connecticut, New Jersey, New York and Pennsylvania are expected to make roads icy for Monday morning commuters.The National Weather Service issued a winter weather advisory, in effect until 10 a.m. Monday for parts of northeastern Pennsylvania and until 11 a.m. for parts of New Jersey, as well as the Lower Hudson Valley in New York.Parts of Connecticut are also expected to be affected, including northern areas of Fairfield, New Haven and northern Middlesex Counties.In northeastern Pennsylvania, forecasters predict up to four inches of snow and sleet, which will turn into a light glaze of ice accumulation Monday morning. Most parts of New York and New Jersey will get less than an inch of snow starting on Sunday evening, spreading eastward into southwestern Connecticut overnight.By late Sunday night, the snow is expected to transition to freezing rain, creating hazardous, icy conditions, particularly on untreated roads and in higher elevations. The morning commute on Monday could be especially dangerous, with icy roads posing significant challenges for drivers, forecasters said.Ice accumulations are forecast to range from a light glaze to a few hundredths of an inch across most areas, while western Orange County may get up to an inch of ice. Higher elevations in the Poconos of Pennsylvania will get the heaviest snow and ice accumulations on Sunday evening, potentially up to four inches.Mike Kistner, a forecaster with the National Weather Service in Binghamton, N.Y., said the forecast for freezing rain and ice is what pushed the Lower Hudson Valley and parts of New Jersey to be under a winter weather advisory, though the snowfall should be light.While the cold air and below-freezing temperatures Monday morning will likely keep roads icy during the morning rush, Mr. Kistner said as it heats up later in the morning and throughout the day, conditions should clear. Bridges and overpasses may remain icy even if the main roads are wet, he added.Jennifer Givner, a spokeswoman for the New York State Thruway Authority, said workers were ready to clear the roads and have pretreated them for freezing rain, though she warned drivers to take it easy on Monday morning.“Give yourself some extra time in the morning,” Ms. Givner said. “And just slow down. I think that’s always the best way to travel in this weather.”Winter weather advisories were also issued for areas in western Maryland, western Virginia, and eastern West Virginia, which could get up to two inches of snow and sleet.The Weather Service warned about slippery roads in those areas. Those advisories were in place until 1 a.m. on Monday.In West Virginia, northwestern Pocahontas County and southeastern Randolph County were under winter storm warnings until 1 a.m. on Monday as strong winds, snow and ice moved in Sunday night.

    My 500-Mile Journey Across Alaska’s Thawing Arctic

    Flames were leaping out of the forest beneath the float plane taking us deep into the remote interior of northern Alaska. Our destination was the glacial Walker Lake, which stretches 14 miles through Gates of the Arctic National Park.Nearly 100 miles from the nearest dirt road, Walker Lake is within an expanse of uninhabited tundra, scraggly boreal forests and the seemingly endless peaks of the Brooks Range in a wilderness bigger than Belgium. Once we arrived, we saw wide bear trails bulldozed through alder thickets and plentiful signs of moose and wolves.We had come here to begin a 500-mile journey that would take us in pack rafts down the Noatak River, believed to be the longest undeveloped river system left in the United States, and on foot, slogging the beaches of the Chukchi Sea coastline. Our goal was to get a close-up look at how warming temperatures are affecting this rugged but fragile Arctic landscape. Worldwide, roughly twice the amount of the heat-trapping carbon now in the atmosphere has been locked away in the planet’s higher latitudes in frozen ground known as permafrost. Now that ground is thawing and releasing its greenhouse gases.The fire we flew over was our first visible sign of the changes underway.While wildfires are part of the landscape’s natural regenerative cycle, they have until recently been infrequent above the Arctic Circle. But now the rising heat of the lengthening summers has dried out the tundra and the invasive shrubs that have recently moved north with the warmth. This is a tinderbox for lightning strikes. The fires expose and defrost the frozen soil, allowing greenhouse gases to escape into the atmosphere.I have slept more than 1,000 nights on frozen terrain while exploring the Far North. My first Arctic venture was in 1983, with a fellow National Park Service ranger in a tandem kayak on the Noatak River in Gates of the Arctic. We awoke one morning, startled by the sounds of a big animal running through low willows. It jumped into the river straight toward our tent — a caribou chased by a wolf. We were relieved it wasn’t a bear.I couldn’t help but feel unsettled, even reduced, by the immense sky and landscape. While the scale of it all seemed too much to process, the Arctic had captured my soul and I set out on numerous other trips across different places in the North.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Strong Storm in San Francisco Brings a Tornado Warning

    Less than two weeks after a tsunami warning, residents were jolted awake before 6 a.m. to consider a new potential disaster scenario.Powerful storms swept through parts of Northern California on Saturday, knocking down trees, causing widespread power outages and prompting weather officials to issue what they said was the first-ever tornado warning for San Francisco.The warning blared from cellphones around 5:45 a.m., jolting residents across the city from their sleep and into the sudden realization that many had long prepared themselves for what to do in the case of a sudden earthquake, but not a tornado.And it came less than two weeks after a similar alert echoed across the Bay Area warning of a different kind of disaster scenario: an impending tsunami that forecasters worried could strike along a vast stretch of the Northern California coast.That warning had been spurred by an earthquake in the Pacific Ocean and briefly caused a panic as people sought to get to higher ground. The warning was canceled a little more than an hour after it was issued.The tornado warning on Saturday, which was in effect for about 30 minutes, was urgent: “Take shelter now in a basement or an interior room,” it read in part.“That is the first time that we’ve issued a tornado warning for San Francisco,” said Crystal Oudit, a meteorologist with the National Weather Service in the Bay Area. She said the service had done so after seeing conditions that tend to favor tornadoes as the storm approached the city.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Millions in Northern U.S. Under Winter Storm Warnings

    Temperatures are expected to plunge after another round of wet, messy, windy weather moves through the Mid-Atlantic, the Northeast and the Upper Midwest on Thursday.Millions of people across the Midwest, Northeastern United States and southern Ontario, Canada, were under winter weather warnings Thursday morning as snow squalls moved through ahead of another blast of Arctic temperatures.After a week of bitterly cold temperatures and days of lake-effect snow, another shot of cold air was sweeping through the Northeast after sending temperatures in parts of the Midwest plunging into the teens, 10 to 20 degrees below normal. Wind gusts up to 50 miles per hour are expected Thursday, bringing blizzard conditions to areas with lake-effect snow and making travel treacherous.Forecasters with the National Weather Service in New York City said that Thursday night into Friday would be the coldest night and early morning of the season, especially after accounting for wind chill.In New York, which experienced one of its warmest Halloweens ever this fall, some welcomed the return of more-seasonable temperatures. At an outdoor Christmas tree lot in Midtown Manhattan on Wednesday, Rosie Roop, 25, a hospitality and business student, was buying a wreath. “I’m happy it’s getting colder,” she said. “I just want it to snow.”Ms. Roop said she had worn her puffy coat for the first time this week. “I definitely like the four seasons,” she said. “I have not been a fan of the murky in-between.”The chilly weather inspired Danny Offermann, 28, an assistant principal at a charter school in the South Bronx, to visit a Christmas tree lot and buy a two-foot tree ($60) for his apartment.How Much Snow To Expect More

    Republicans Would Regret Letting Elon Musk Ax Weather Forecasting

    One way Donald Trump may try to differentiate his second term from his first is by slashing the federal work force and budget and consolidating and restructuring a host of government agencies.For people who care about weather and climate, one of the most concerning proposals on the table is to dismantle the National Oceanic and Atmospheric Administration. The authors of Project 2025, a blueprint for the administration crafted by conservative organizations, claim erroneously that NOAA is “one of the main drivers of the climate change alarm industry” and should be “broken down and downsized.” An arm of Mr. Trump’s team, the Department of Government Efficiency, to be led by Elon Musk and Vivek Ramaswamy, wants to eliminate $500 billion in spending by cutting programs whose funding has expired. That could include NOAA.With the rising costs of and vulnerability to extreme weather in a changing climate for the United States, dismantling or defunding NOAA would be a catastrophic error. Rather, there is a golden opportunity to modernize the agency by expanding its capacity for research and innovation. This would not only help Americans better prepare for and survive extreme weather but also keep NOAA from falling further behind similar agencies in Europe. While the incoming administration may want to take a sledgehammer to the federal government, there is broad, bipartisan support for NOAA in Congress. It is the job of the incoming Republican-controlled Congress to invest in its future.NOAA was established via executive order in 1970 by President Richard Nixon as an agency within the Department of Commerce. Currently its mission is to understand and predict changes in the climate, weather, ocean and coasts. It conducts basic research; provides authoritative services like weather forecasts, climate monitoring and marine resource management; and supports industries like energy, agriculture, fishing, tourism and transportation.The best-known part of NOAA, touching all of our daily lives, is the National Weather Service. This is where daily forecasts and timely warning of severe storms, hurricanes and blizzards come from. Using satellites, balloon launches, ships, aircraft and weather stations, NOAA and its offices around the country provide vital services like clockwork, free of charge — services that cannot be adequately replaced by the private sector in part because they wouldn’t necessarily be profitable.For most of its history, NOAA has largely avoided politicization especially because weather forecasting has been seen as nonpartisan. Members of Congress from both parties are highly engaged in its work. Unfortunately, legislation introduced by Representative Frank Lucas, Republican of Oklahoma — a state with a lot of tornadoes — that would have helped NOAA to update its weather research and forecasting programs passed the House but languished in the Senate and is unlikely to move forward in this session of Congress. However, in 2025 there is another opportunity to improve the agency and its services to taxpayers and businesses.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Lake-Effect Storm Bringing Heavy Snow to Great Lakes Region

    Forecasters warned that some areas would be “paralyzed” by the snow as some sections of highways in New York and Pennsylvania were closed on Friday.A lake-effect storm in the Great Lakes region that was bringing heavy snow to parts of northern New York, Ohio and Pennsylvania on Friday prompted the closure of highways, disrupting travel after the Thanksgiving holiday, as forecasters warned the storm would “bury” some areas east of Lakes Erie and Ontario.The storm, which began earlier in the week, had already brought more than eight inches of snow to portions of Marquette County in Michigan’s Upper Peninsula by Friday afternoon, according to the National Weather Service.Portions of Western New York, such as Mayville on the northern end of Chautauqua Lake about 22 miles north of Jamestown, had recorded 17 inches of snow by midafternoon on Friday, according to forecasters.Watertown, N.Y., where less than an inch of snow had fallen on Friday afternoon, was forecast to get close to six feet of snow over the next three days.Gov. Kathy Hochul of New York declared a state of emergency for 11 counties on Friday.“We are so accustomed to this kind of storm,” Ms. Hochul said in an interview with Spectrum News on Friday. “We don’t love it, but it is part of who we are as New Yorkers, especially western New York and the North Country.”The National Weather Service in Buffalo said the prolonged lake-effect snow “will bury some areas east of both Lakes Erie and Ontario.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Scenes From the Atmospheric River That Drenched California and the Pacific Northwest

    A gusty, rain-soaked storm swept through the Pacific Northwest and Northern California this week, killing at least three people and knocking out power for hundreds of thousands of customers.The dangerous weather, fueled by the season’s first major atmospheric river from the Pacific Ocean, battered the region starting on Tuesday. Forceful winds wiped out power for half a million customers in Washington. Among the places hardest hit was the Seattle area, where falling trees killed two people. The storm then moved into Northern California, where it disrupted hundreds of flights, flooded creeks, drenched San Francisco and brought heavy snow to parts of the Sierra Nevada and Cascade mountain ranges. On Saturday, a body was recovered in floodwaters in Sonoma County, local authorities said. Though the storm is weakening as it inches south, residents are still reeling from the damage. More than 90,000 customers in Washington were still without power on Saturday morning, along with about 17,000 in California. In the region north of San Francisco, which includes Napa Valley, flooding is expected to continue through Saturday.Here are photos of the storm’s toll this week.Saturday, Nov. 23Hale Irwin/Sipa, via Associated PressCars drive on a snowy highway over Donner Summit in California.ReutersWater rescue teams deployed in Forestville, Calif.Friday, Nov. 22Mike Kai Chen for The New York TimesA cyclist rides through a flooded intersection in San Francisco.Mike Kai Chen for The New York TimesFog rolled in around the Golden Gate Bridge in San Francisco.ReutersFlooding in Santa Rosa caused road closures and detours.Rachel Bujalski for The New York TimesSome streets were flooded in Rohnert Park, Calif.Rachel Bujalski for The New York TimesStaci Harpole looks over a flooded vineyard off Wohler Road in Forestville.Noah Berger/Associated PressA mudslide near a home in Sonoma County, Calif.Rachel Bujalski for The New York TimesFlooding in Santa Rosa, Calif.Stephen Lam/San Francisco Chronicle, via Associated PressLivestock graze on a patch of grass surrounded by the swollen Eel River in Ferndale, Calif.Thursday, Nov. 21Mason Trinca for The New York TimesA giant tree fell on Front Street in Crescent City, Calif.Justin Sullivan/Getty ImagesPolice officers help a woman walk through a flooded parking lot in Santa Rosa.ReutersRoads and vineyards were flooded in Sebastopol, Calif.Justin Sullivan/Getty ImagesPolice officers wave to a car trying to drive through a flooded parking lot in Santa Rosa.KOMO via Associated PressEmergency crews responded to a downed tree in Issaquah, Wash.Wednesday, Nov. 20David Ryder/ReutersResidents survey storm damage in Seattle.Mathieu Lewis-Rolland/Getty ImagesTara Brown surveys storm damage while walking her dog in Lake Stevens, Wash.Noah Berger/Associated PressUtility workers tend to downed power lines in Sonoma County.Mathieu Lewis-Rolland/Getty ImagesTiffani Palpong stands in front of her property in Lake Stevens where her son was trapped by downed power lines and trees.Noah Berger/Associated PressIsabella Karamitsos, a U.S. Geological Survey employee, deploys a sensor to measure water flow in Santa Rosa.Kate Selig More
