In Southern California, the flooding could be life-threatening in areas burned by wildfires. California is about to get soaked, whipped and dumped on again. A robust storm system will sweep in from Wednesday night into Friday, bringing the threat of strong winds, heavy rain or snow to every part of the state.

The strongest storm in a year is set to pound Southern California this week, with forecasters warning of potential widespread roadway flooding and the chance of landslides throughout the region — especially in areas recently charred in the devastating Los Angeles County firestorms.
