California Flash Floods and Mud Slides

I had noted only just yesterday (in a comment about the El Nino), that increased rainfall in southern California would result in more flash floods and mud slides because of the loss of vegetation to help absorb the moisture and prevent erosion.  Today, The Daily Mail ran this headline: "Violent storms and flash floods cause chaos in California as 5ft-deep mud engulfs cars and traps people inside homes north of LA." Fortunately, there were no fatalities according to the article. Here are a couple articles discussing what to do if you happen to be in a car caught in a flash flood:

• "Flash Flooding: Your Vehicle Can Be Biggest Danger"--The Weather Channel.
• "Tips for Drivers Caught in a Flash Flood"--ABC News.

From the latter article: "Underwater rescue experts have a handy acronym for motorists to keep in mind, POGGO. It stands for: First, pop your seat belt. Next, open a window. Then grab your baby and go."
