California braces for 2nd, even heavier rain storm that could bring life-threatening flash flooding

As Californians clean up from a rain storm that inundated the state Thursday, they're already bracing for a second, even stronger storm that could bring life-threatening flash flooding from Santa Barbara to Los Angeles.

1st storm

The first storm pummeled Southern California with heavy rain Thursday, leading to flash flooding, road closures and water rescues.

Santa Barbara County recorded over 6 inches of rain while San Diego County saw more than 3 inches of rain. Los Angeles got a record 2.37 inches of rainfall.

On Friday, the storm is moving inland into the Rockies, where 1 to 2 feet of snow is forecast. Winter storm alerts were issued for several states from Montana to New Mexico.

As the storm continues to move east, Texas could get severe thunderstorms with large hail and damaging winds later on Friday. Cities in the bull's-eye of these severe storms will be San Antonio, Austin, San Angelo and north to Abilene. Dallas and Houston will see strong thunderstorms later on Friday night.

Sunday night into Monday early afternoon, the life-threatening flash flooding will concentrate on Los Angeles.

The National Oceanic and Atmospheric Administration is already warning that this could be a life-threatening situation; the agency issued its second-highest level of flood threat for Santa Barbara and Los Angeles counties.

Evacuation warnings were issued on Friday for parts of Santa Barbara County due to the incoming storm's "potential to produce flash flooding, debris flows and landslides." Emergency officials said residents should be ready to leave at a moment's notice, while people with disabilities and those with large animals should leave now.

The heavy rain threat will move into San Diego Monday afternoon into Monday night.

Lighter rain will continue for Southern California into Tuesday and Wednesday.

Parts of the central California and Southern California coastline could see 6 to 12 inches of rain from the massive storm.

In the Sierra Nevada mountains, heavy snow could reach 2 to 4 feet -- the biggest snowfall of the season for the highest elevations.
