The National Weather Service has issued a flash flood watch for San Diego County, including Rancho Bernardo, due to expected heavy rain beginning late Friday that could cause mudslides.

About .43 inches of rain fell in RB during Wednesday's storm, and another one to two inches are expected over the weekend. The NWS urges driver caution, as the roads should be slick during the storms. The California Highway Patrol reported about on Wednesday as on a non-rainy day.

A flash flood watch—different from a flash flood warning—means flash flooding is possible. A warning indicates that flooding is imminent or occurring. Sandbags, but not sand, are available at at 16966 Bernardo Center Dr. There is a limit of 10 per household.
