Flood Watch Set For LA County: Up To 8 Inches Of Rain Expected

LOS ANGELES, CA — As a second, more powerful storm system enters Southern California this week, the National Weather Service has issued a flood watch for Los Angeles County beginning at 10 p.m. Tuesday.

The flood watch runs through Thursday night. Forecasters estimate that much of LA County could receive 2 to 4 inches of rain as a new storm hits the region Wednesday and Thursday on the heels of the lighter storm of earlier this week, according to the NWS.

"A stronger storm will bring several hours of steady moderate to heavy rain and gusty winds Wednesday and Thursday, with threats for flooding and thunderstorms," forecasters said.

South-facing foothill areas and coastal slopes could see the brunt of the storm, with up to 8 inches of rain possible in those areas, the NWS said.

Rainfall rates of 0.3 to 0.6 inches per hour could hit some areas; if thunderstorms develop some areas could see an inch an hour, according to the NWS.

Low-lying areas, roads and creeks and streams are at risk of flooding. Flash floods and debris flows could impact recent burn scars.

"There will be the strong potential for rock and mudslide activity, especially on canyon and mountain roadways. Flooding and rock/mudslide activity may lead to significant travel delays and road closures. Increased flow in rivers and streams will bring an increased threat for swiftwater rescues," the NWS said.

The precipitation is expected to stop by Friday.

Sandbags are available to homeowners for flood control at both Los Angeles County and Los Angeles city fire stations.
