More heavy rain, flooding risk heads to Southern California

After an atmospheric river dumped heavy rain and strong winds on parts of Southern California earlier this month, more weather woes were on the way to the region on Nov. 21 with forecasters warning of additional rain and flash flooding. Two back-to-back low pressure systems are set to impact Southern California and the Desert Southwest on Nov. 21 and 22, the National Weather Service said. … The second system will come right on the heels of the first, keeping most of the heavy rain over Mexico but creeping up into Arizona and New Mexico by the end of the weekend, the weather service said.
