A historic weather front that slammed a wide swath of Southern California with stunning snow, record rains, and flooding that prompted air rescues eased its grip Sunday — but more harsh weather is expected this week across the state.

The first of two new storms brought rain and snow Sunday to northern California. Blizzard warnings will go into effect at 4 a.m. Monday and will last until Wednesday for much of the Sierra Nevada.

“Extremely dangerous and near to impossible mountain travel is expected due to heavy snow and strong wind,” the weather service’s Sacramento office warned on Twitter.

The snow won’t sweep down to the edge of coastal cities as it did in recent days, but this week’s forecast for Los Angeles does call for high temperatures in the low 50s — about 15 degrees below normal.

More than 61,500 homes and businesses in the state remained without power Sunday afternoon after days of fierce winds, rains, and snow that toppled trees and downed power lines.

“A remarkable storm the last few days with historic amounts of precip and snow down to elevations that rarely see snow,” forecasters with the weather service in Los Angeles wrote. 

Meteorologist Mark Moede said the winter storm would “exit Southern California this morning and there will be a brief break in the weather” but that rain and mountain snow is expected to return Monday through Wednesday.

Meanwhile, millions of Americans were also bracing for dangerous conditions, from ice storms in Michigan to tornadoes in Texas.

Developments:

• More than 7 inches of rain fell in Ventura County northwest of Los Angeles, causing flash flooding that left cars stranded on roadways Saturday.

• Los Angeles Fire Department ground and air responders rescued four people and five animals from flooding in Encino, California, about 25 miles northwest of downtown Los Angeles.
