If the rain falls at a steady, lighter rate, Southern California could be in good shape. That could mean enough rain to help ease the firefighting strain, but not enough to trigger another potential disaster. Heavier rain could mean the chance for flash flooding or mudslides over fresh burn scars.

San Diego's dry conditions greatly increased the risk for wildfires. “We’ve been experiencing extreme fire behavior throughout Southern California as many have seen," said Rob Johnson, public information officer for CAL Fire.

The Eaton and Palisades fires ignited nearly four weeks ago during a historic wind event that has seen the two fires kill at least 28 people, burn nearly 37,500 acres and destroy thousands of homes and businesses.
