SOUTHERN CALIFORNIA, CA. (Pain In The Pass) >> A low-pressure system hanging off the coast of California and from a dying Tropical Storm Mario down in Baja Mexico is expected to bring a couple days of rainfall with thunderstorms and potential flash flooding to parts of California.

The Southern California Weather Force has issued a Flood Watch for Southern California on Wednesday September 17 through Friday Sept. 19. The peak rainfall day will be on Thursday.

This isn’t a normal ‘monsoon’ burst for the mountain and desert areas, SCWF said.

The rain showers and thunderstorms should clear out by Saturday.
