The wet weather will bring relief to Southern California after a prolonged period of dryness, but there’s concern that any bursts of heavy rainfall could cause flooding.

There is a 10% to 20% chance of flash flooding and landslides in some recently burned areas of Los Angeles County, forecasters say, including the Palisades and Eaton fire areas.

The National Weather Service issued a flood watch effective from 4 p.m. Sunday to 4 p.m. Monday for areas in or near burn scars created by the Palisades Fire, Eaton Fire, Hughes Fire and Bridge Fire, the latter blaze of which burned 56,000 acres last fall.

The first significant rainfall in several months will spread across Southern California this weekend, giving a badly needed sip of water to an area parched by drought and devastated by multiple raging wildfires.
