Residents face new threats of mudslides and ‘toxic ash’ as rain hits Southern California - Seven fires are still raging across Southern California and have consumed more than 57,000 acres

The National Weather Service said there is a 15-25% chance of thunderstorms across the region, which could bring periods of heavy rainfall that could overwhelm the burn-scar areas.

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.
