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 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.

A cold system will arrive in the Los Angeles area Saturday afternoon, bringing the possibility of rain through Monday morning, and increasing the potential for mudslides and debris flow.
