A "river in the sky" has poured down on California, causing flooding. Thousands are under evacuation orders as another storm is set to come on Monday. First responders and the California National Guard had to save over 50 people overnight from the water overnight, AP reports. Approximately 15 million people are under flood watches in California and Nevada as a second "river in the sky" approaches, CNN reports. They added that it "won't take long once the steady heavy rain gets started for flooding impacts to resume."
LOS ANGELES, March 9 (Reuters) - Flood watch notices were posted across northern and central California for Thursday ahead of an atmospheric river storm expected to douse much of the state with heavy rain, including mountain areas still buried from a near-record snowfall. But smaller, waterfront communities along several major rivers and their tributaries also braced for the possibility of overflowing streams swollen by heavy showers and runoff of melting snow. Elsewhere, the NWS issued "prepare now" alerts for residents along the Big Sur, Carmel, Salinas and Pajaro rivers. "It's really a combination of all this heavy rainfall coming and also rapidly melting snow." The looming deluge follows a three-week barrage of nine atmospheric river storms that struck California in late December through mid-January, triggering widespread flooding as well as hundreds of mudslides, rockfalls and sinkholes across the state.

REUTERS/Aude GuerrucciFeb 25 (Reuters) - Nearly 85,000 households and businesses were without power in the Los Angeles area on Saturday, as storms continued to pummel parts of California, bringing snow to higher elevations and dumping rain and hail in the flatlands. In Southern California, "this is a rare case of a cold, significant storm event," Jackson said. On Saturday, scattered showers and isolated thunderstorms were expected to bring rain, hail and a mixture of snow and moisture called "graupel" to the area, the National Weather Service said.

In Southern California, "this is a rare case of a cold, significant storm event," Jackson said. SEVEN FEET OF SNOW IN SOME SPOTSEven before the latest storm in California, much of the state has experienced an unusually rainy, chilly winter. Heavy rain will inundate many parts of California through Saturday, the weather service said.
The storm hit California on Tuesday and was expected to continue through the end of the week. In Central California, the weather iced over roadways, the weather service reported. More than 100,000 homes and businesses were without power, largely in Central California, according to the tracking site Poweroutage.us. Among the hardest-hit cities was Minneapolis, where some 20 inches (50 cm) of snow and 45-mph (72-kph) winds were expected to create whiteouts. The storm wreaked havoc on morning air travel as hundreds of flights were delayed or canceled across the nation.

Jan 16 (Reuters) - Authorities in California were set to assess damage on Monday after a wave of storms killed at least 19 people, swept away scores of homes and forced thousands to evacuate. Small rainstorms lingered early on Monday from San Francisco through central California and a few inches of snow fell on the foothills of the Sierras, the National Weather Service reported. "It's coming to an end as we speak," said meteorologist William Churchill on Monday morning at the National Weather Service (NWS) Weather Prediction Center in College Park, Maryland. The Russian River, swollen with floodwater following a chain of winter storms, flows past the town of Guerneville, California, U.S. January 15, 2023. Then most of the state will have sunny days and at least a 10-day spell of dry, cool weather.

The latest storm, the season's eighth, is expected to begin dumping heavy rain on California from early on Saturday, the National Weather Service's Weather Prediction Center said. The ninth and final atmospheric river of the series is due to make landfall on Monday and last a couple of days. Among the waterways of concern, the Salinas River in northern California flooded roads and farmland on Friday, when 24,000 people were urged to evacuate. In southern California, officials will release water on Saturday from Lake Cachuma, which provides drinking water near Santa Barbara, as the chronically low lake has filled to capacity.
In their 2023 outlook, Goldman analysts noted that disagreement about the economic forecast abounds within their own circles. Bill Dudley, a former Goldman Sachs partner and president of the New York Fed, puts the chance of recession this year at about 70%. Goldman analysts say that even with a sour economy, they predict the 2023 investment return on the S&P 500 will most likely be between 9-12%. The Fed’s days of three-quarter-point rate hikes are behind us, said Philadelphia Federal Reserve President Patrick Harker in a blog post Friday. Better-than-expected price data shows that the Fed’s aggressive and economically painful rate hikes are successfully slowing the economy and fighting inflation, he said.
The parade of storms is forecast to continue, bringing even more heavy rain next week, the weather service said.

An aerial view shows the damage after rainstorms caused a levee to break, flooding Sacramento County roads near Wilton, California, U.S., January 1, 2023. Another atmospheric river storm is threatening California with flooding, landslides, and power outages on Wednesday as millions of residents recover from several destructive storms, one of which caused a levee breach this weekend. Flood watches are in effect across Central and Northern California, where the ground has become more saturated and vulnerable to flooding and rapid runoff. San Mateo County, located south of San Francisco, declared a local state of emergency and activated its emergency operations center. In south Sacramento County, responders are attempting to repair part of a 34 mile levee system along the Cosumnes River, which protects land made up mostly of vineyards and cattle ranches, before the storm is set to arrive on Wednesday.
Some airlines, including Southwest, no longer have automatic agreements in place that allow for rebooking on another airline free of charge, she said. He and his family spent Christmas in Austin, Texas, and intended to fly home to Raleigh, North Carolina, on Dec. 26 via Southwest. “What are you going to do if the airline can’t save you?” Bangs said. Sallyann Koontz got stuck in Austin after her Southwest Airlines flight home to Charleston, South Carolina, was canceled. "It has served the public with affordable flights and possibly allowed travel for less affluent families for decades," Koontz said of the airline.
Poloncarz updated the death toll from the blizzard on Wednesday, reporting 37 deaths in Erie County, with one other storm-related fatality in neighboring Niagara County. The goal was to get at least one lane of traffic open on each street by Wednesday night, Poloncarz said. The mercury climbed above freezing on Wednesday, and forecasts called for the thaw to continue with spring-like temperatures and showers likely by week's end. "We're actually expecting a rapid melt over the next two days, because we're going to hit 50 degrees (Fahrenheit)," Poloncarz said. Showers and thunderstorms are expected in the Gulf Coast and lower Mississippi Valley, the weather service said.
"We're recovering from the worst storm I've ever seen, certainly in terms of death from mother nature's wrath," he said. Progress was slow due to the sheer volume and depth of the snow, which Poloncarz said "is not plowable." [1/7] A "let’s go Buffalo" sign is seen behind an abandoned car on the road following a winter storm in Buffalo, New York, U.S., December 27, 2022. New York Governor Kathy Hochul called it an "epic, once-in-a-lifetime" weather disaster, the worst blizzard to hit the Buffalo area in 45 years. Buffalo residents with plows attached to their Jeeps and pickup trucks helped clear side streets.

Almost all electricity was restored by Wednesday morning and temperatures were warming as Buffalo continued to dig out. The goal was to have at least one lane of traffic open on each street by Wednesday night, Poloncarz said. Melting snow presents a risk of flooding and about 1/4 inch to 1/2 inch of rain is expected in Western New York on Friday and Saturday.

"It's still snowing" in Western New York, said NWS meteorologist Bob Oravec, predicting two more inches. "This is probably the last of the snow," added Oravec, who is with the NWS Weather Prediction Center in College Park, Maryland. Buffalo, New York state's second largest city, was ground zero for the blizzard that took shape on Friday. Poloncarz, speaking at a press briefing Tuesday, urged residents to stay home and the curious to stay away.
As the storm took shape over the Great Lakes on Thursday, a weather phenomenon known as a bomb cyclone was likely to develop from a "rapidly deepening low-pressure" system, the National Weather Service (NWS) said. The cyclone could spawn snowfalls of a half inch (1.25 cm) per hour and howling winds from the Upper Midwest to the interior Northeast, producing near-zero visibility, the weather service said. "It's dangerous and threatening," President Joe Biden said at the White House, urging Americans with travel plans to not delay and to set off on Thursday. Hundreds of Texans died in February 2021 after the state's power grid failed amid wintry storms, leaving millions without electricity. Greg Carbin, chief of forecast operations at the NWS Weather Prediction Center in Maryland, said freezing or below-freezing cold would bisect central Florida, with temperatures about 25 degrees below normal.
A blast of Arctic air will also plunge much of the country into bitter and, in some cases, dangerous cold, forecasters say. In some parts of this area, the wind chill could reach as low as minus 70 degrees, according to the Weather Service. Brief bursts of moderate to heavy snow lasting an hour or two are likely to occur immediately behind the Arctic front. Strong southerly winds, combined with the new moon-tide cycle, could also bring coastal flooding from northern New Jersey to northeast Massachusetts, the Weather Service said. Meteorologists warned local residents that this is not a normal lake effect event with a narrow band of heavy snow.
In its wake, the cyclone could spawn snowfalls of a half inch an hour and winds of more than 50 mph (80 kph) in the Upper Midwest and interior Northeast, the weather service said. "This will lead to dangerous, to at times impossible, land and air travel leading up to the holiday weekend," the agency said on its website. Temperatures in parts of the Southern Plains and Southeast could stay below freezing -- 30-plus degrees less than normal -- for multiple days, the weather service predicted. The weather service also warned of freezing rain in parts of Oregon and Washington in the Northwest, where the storm originated, late Thursday. That would be the biggest daily drop in output since the freeze of February 2021 when a winter storm cut gas supplies from Texas and forced the Texas electric grid operator to impose rolling power outages.
"It does not look like a good day to be traveling across the Midwest on Friday," said Greg Carbin, chief of forecast operations at the NWS Weather Prediction Center. The biggest risk exists in the states of Kansas, Nebraska and Iowa, as well as parts of Wisconsin, Illinois, Indiana and Michigan. Southern states could have rainfall and thunderstorms through Thursday, after which temperatures could drop significantly. The NWS also warned of "bone-chilling" cold in parts of Washington state through the Northern Plain states, including Montana, Wyoming and the Dakotas. Parts of Montana could see the thermometer register below minus 20 degrees Fahrenheit (-29 C) on Tuesday, according to the NWS.
More than 18 million people from Texas to Mississippi are under threat of severe storms Tuesday, including tornadoes. In Mississippi, the Meridian Public School District – which serves over 4,900 students – announced they will be closed Wednesday due to the threat of severe weather. The Lawrence County and McComb School Districts also announced they were closing Wednesday due to the threat of severe weather. The Mississippi Emergency Management Agency also noted the severe weather expected in the state and asked residents to prepare. “With severe weather expected throughout Mississippi tonight and tomorrow, please review your severe weather preparedness checklist to make sure you are ready for the storms,” the agency said in a message on Twitter.
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. More than a dozen western states are under winter weather alerts this weekend as the potent storm system moves across the region. Heavy rain will also be notable up and down the West Coast, particularly in California, where flooding concerns exist through Sunday. Similar to a fire hose, it shoots moisture into one area for an extended period of time, resulting in very heavy rain or snow.
CNN —Back-to-back-to-back systems will make their way across the United States over the next few days, with the last – and largest – storm bringing heavy rain, blizzard conditions and the potential for tornadoes. Along the coast, heavy rainfall and gusty winds will hammer the area with 1 to 2 inches of rainfall expected through Friday … before the main event arrives. Flash flooding, blizzard conditions and tornadoes possible next weekA blockbuster storm looks to be taking shape in the West for this weekend into early next week, threatening flash flooding, blizzard conditions and tornadoes. “As the system moves into the Plains early next week, a spring-like storm system develops,” Myers said. That threat is also increasing across the southern Plains and Gulf Coast region.
Stay safe during a solar storm by preparing to lose power, printing out maps, and staying off planes. What is a solar flare and how do they affect Earth? CMEs primarily affect the magnetosphere, jostling Earth's magnetic field lines in an event called a geomagnetic storm, also known as a solar storm. NASAGetting ready for the possibility of a major solar flare isn't that different from getting ready for any other disaster. If you follow the basics of disaster preparedness, you'll probably be ready for a solar flare.
CNN —Several days of heavy rain are forecast across portions of the southern US this week, which could improve persisting drought conditions but also lead to significant flooding. “The threat for flooding will start late Monday into early Tuesday for areas south of I-40, especially near the Alabama border,” the National Weather Service office in Nashville, Tennessee said. “If rainfall becomes especially heavy or pockets of heavy rain move across the same areas repeatedly, more significant flash flooding will occur,” the weather service in Nashville warned. Many locations across the southern US could see rain every day this week, including Memphis, according to the weather service. “Flooding may develop, starting early in the week for low lying and flood prone areas, and along small streams,” the weather service in Nashville said.
The winter storm that dumped up to two feet of snow across the Cascades and the northern Rockies in the Northwest on Thursday will impact the Central US Friday. Check your forecast here“The cold front has featured everything from 82 mph winds to snow squall conditions to thundersnow,” the National Weather Service office in Salt Lake City said. With several feet of new snow in the mountains, an avalanche warning has been issued for the Central Sierra, including Greater Lake Tahoe through Friday evening. “Confidence has also increased in blowing dust including the potential of a wall of dust developing along the cold front,” the weather service warned. The weather service in Eureka, California, noted the “possibility of isolated thunderstorms capable of producing small hail” near the coast.
