Southern California Experiencing 'High Risk' Of Serious Flooding as Atmospheric River Continues

A powerful storm tapping into an atmospheric river has pummeled California since Sunday, triggering serious flooding and landslides while also producing damaging winds in the state. The highest risk of flooding on Monday is ongoing in Southern California this morning, where it will continue into the daytime.

NOAA's Weather Prediction Center has issued the highest flood risk level for the Los Angeles metro on Monday. This area, shown in pink on the map, could experience the most serious additional flooding rainfall, landslides, rockslides and travel disruptions. Flooding is also possible as far south as the San Diego area today.

There have been more than 100 reports of flooding and landslides in Northern and Central California since Sunday.

Los Angeles received 4.10 inches of rain yesterday, which is more than the city averages in the entire month of February. Storm total rainfall is generally 5 to 10 inches from near Los Angeles into areas northwest of there, with the highest totals in the mountains.

The strongest winds from this storm occurred Sunday. Wind gusts over 90 mph were reported, including gusts of 102 mph in Lagunitas-Forest Knolls in Marin County, 98 mph near Lexington Hills in Santa Clara County and 94 mph near Grapevine.

Southern California will see the heaviest additional rain on Monday, lingering into Tuesday. Totals will be 1 to 5 inches on top of what has already fallen on Sunday. Storm totals will be 6 inches or more in much of Southern California, with 8 to 10 inches of storm totals likely to the northwest of Los Angeles, or north of Santa Barbara.
