Californians Warned to Flee, Head to High Ground as Waters Rise

After years of drought, California is in a long flood fight as waves of storms roll in off the Pacific, killing at least 14 people, closing highways and schools and sending residents fleeing for their lives.

(Bloomberg) — After years of drought, California is in a long flood fight as waves of storms roll in off the Pacific, killing at least 14 people, closing highways and schools and sending residents fleeing for their lives.

The parade of storms since the end of December is one of the biggest tests yet for disaster-weary California, which has endured a crucible of wildfires and extreme heat in recent years as global warming makes weather ever-more extreme.

On Monday residents in the tony coastal enclave of Montecito, home to Oprah and Prince Harry, were told by state officials in a tweet to “LEAVE NOW” while shelter-in-place orders were issued in other parts of Santa Barbara County. Several other towns throughout the state advised residents to get out before more rivers flood.

“California is experiencing coincidentally a drought emergency and a flood emergency,” said Department of Water Resources Director Karla Nemeth during a media briefing Monday.

Highway 1, pathway to the state’s renowned coastal area of Big Sur, was closed following a mudslide, according to the California Department of Transportation website. In addition, the westbound lanes of Interstate 80 near Sacramento, the state capital, have been shut by floods and many other roads throughout the state have been closed. 

Emergency shelters were opened in Santa Cruz County, about 75 miles (121 kilometers) south of San Francisco, where the San Lorenzo River rose 17.7 feet (5.4 meters) since Sunday and towns throughout the area flooded. Levels on the river probably have peaked but there will be another round of intense rain later, said Daniel Swain, a climatologist at the University of California, Los Angeles. People in nearby communities were told to evacuate.   

Sacramento County on Sunday told about 3,300 people in the Central Valley town of Wilton ahead of Monday’s deluge to evacuate due to the risk of flooding if levies overflow, said county spokesperson Matt Robinson. Many downed are being removed to clear roads, he added.

Five rivers are being monitored for flooding including the Cosumnes River in Sacramento County and the Russian River in Napa and Mendocino counties in Northern California, according to Jeremy Arrich, flood management manager of the Department of Water Resources, said during the press briefing.

Heavy rain started falling Sunday night in many regions, and more than 100,000 people are without power mostly in northern and central California, according to PowerOutage.us. That’s down from more than 500,000 on Sunday after an earlier storm over the weekend.

The new storm may dump 2 to 5 inches (5 to 13 centimeters) of rain in some areas and 1 to 4 feet of snow in the Sierra Nevada, a mountain range in Eastern California, said Ashton Robinson Cook, a forecaster with the US Weather Prediction Center. Wind gusts may reach upwards of 50 miles per hour in many places. 

Avalanche warnings have been posted in a number of areas through the Sierra Nevada through Wednesday, according to the National Weather Service. “Any steep slopes could be dangerous,” the weather service said.

The storm is another in a series of atmospheric river events, long streams of moisture that can stretch for thousands of miles across the Pacific and then deliver as much water as flows through the mouth of the Mississippi River when they’re wrung out on California’s mountains. The storms already have caused more than $1 billion in losses and damages, according to an estimate by AccuWeather Inc. 

While the precipitation might slack in northern areas overnight, another round of rain will roll in off the Pacific Tuesday, said Richard Bann, a forecaster with the US Weather Prediction Center. It won’t be as severe as Monday’s deluge but with the ground so heavily saturated it won’t take much to cause problems.
