Cleanup efforts underway across Southern California ahead of another storm

More than 22 million people in Southern California are under a flood watch through at least Saturday evening as a storm will bring several rounds of significant rain to the region.

The storm is expected to last through the weekend, elevating the risk for flash flooding, mudslides and debris flows.

Because of that, evacuation warnings are in place for several areas of Southern California.

The greatest risk in burn scar areas will be between 8 p.m. Friday and 3 p.m. Saturday when the the heaviest rain is expected. Rainfall rates could reach 1 inch per hour or great, especially during any thunderstorms.

A storm is moving into Southern California and some of the heaviest rain is coming down in Ventura County.

As the area gets hit with rain, there are mudslide and debris flow concerns in the Mountain Fire burn area. Last year's fire devastated neighborhoods in Camarillo Heights.

Evacuation warnings are in place for the burn scar area, as well as Matilija Canyon, through 6 p.m. Sunday.

The county has deployed 40 extra firefighters and three engines in case the hillsides give way.

"Our concern with this rainstorm is there's a variance in the expectations," said Andrew Dowd with the Ventura County Fire Department. "There's a variance in what the models are looking at, so if we see a heavy downpour, a significant amount of rainfall, especially over a concentrated area we might exceed the debris flow thresholds.

"Right now, the current models show that we will not exceed those debris flow thresholds, but we want to be prepared just in case it happens."

The heavy rain could be extremely problematic for hillside neighborhoods, including much of the massive Eaton Fire burn zone.

In Sierra Madre, residents have been gearing up for possible flooding and debris flows. People living in canyon communities have been filling up sandbags and putting up K-rails.

"If we have significant rain over the next week, we can expect more of the same like we had in February where the mud went into my neighbor's homes, blocked the roads and shut the canyon down," said Glenn Lambin, who lives in Sierre Madre.

Some homes are still yellow-tagged as residents work to repair damage from that February storm.
