An intense, long-lasting atmospheric river is moving into California Sunday, bringing the potential for “life-threatening” flooding, mudslides and widespread power outages as it dumps heavy rain and snow. Follow our live coverage here. This is what’s happening:
• Rare high risk for flooding: A rare Level 4 of 4 risk of excessive rainfall was expanded Sunday to include Los Angeles, in addition to Santa Barbara and Oxnard in Southern California, with the weather prediction center warning of “life threatening flash and urban flash flooding.” Rainfall rates up to an inch per hour will bring 3 to 6 inches of rain across the area. A more widespread Level 3 risk exists for much of coastal California, including San Francisco.
• A month’s worth of rain possible in Los Angeles: In Central and Southern California, widespread rainfall totals of 3 to 6 inches are expected – more than a month’s worth of rain for most. There are indications the storm may be as strong as Tropical Storm Hilary from last August, Los Angeles Mayor Karen Bass said during a news conference Friday, and encouraged residents to take “common sense precautions.”
• Some residents told to evacuate: Mandatory evacuation orders have been issued for communities in Santa Barbara, San José, Los Angeles and Ventura County. Officials warned residents of potential “life-threatening” floods and landslides from the atmospheric event. Several school districts in Santa Barbara County have also canceled classes on Monday due to the severe weather.
• First ever hurricane force wind warning: The National Weather Service in San Francisco on Sunday issued its first ever hurricane force wind warning since records have been kept. Wind advisories and high wind warnings are also in effect for nearly 30 million people in inland areas across nearly the entire state from Redding to San Diego.
• “Near impossible” travel in the mountains: The storm is also expected to bring significant snowfall totals in eastern California and along the Nevada border. Heavy wet snow will spread across the Sierra Nevada through Monday with accumulation rates of 2 to 3 inches per hour, according to the weather service. Dangerous wind gusts are expected to produce whiteout conditions making travel above 5000-6000 feet “near impossible,” the weather service said.
• Power outages growing: Powerful winds will also be a concern across much of the state with widespread winds of 40 to 60 mph and some gusts as high as 95 mph in the foothills and mountains. More than 150,000 customers are without power in the state, according to the tracking website PowerOutage.us. The number of outages is expected to rise as downed trees get tangled with power lines Sunday and Monday, forecasters warned.
• Sporting events affected: Both NASCAR and PGA canceled events scheduled in California over the weekend due to the severe weather. NASCAR moved the Busch Light Clash at the Los Angeles Memorial Coliseum from Sunday to Saturday night, and the PGA Tour announced it would postpone Sunday’s final round of the Pebble Beach Pro-Am golf tournament, to Monday.

State braces for flooded roadways and swollen rivers
This atmospheric river – a long, narrow moisture band that carries saturated air thousands of miles then discharges it like a fire hose – comes right on the heels of another storm that brought record…
