Rain is expected to dampen Mother’s Day weekend across the Southern California, the National Weather Service reported Friday.
A low pressure system will likely bring a chance of rain and a slight chance of thunderstorms to the region this weekend.
Rain will be isolated and scattered throughout the region.
The storm system will move out of the area by Sunday, when only cloudy skies are in the forecast.
Rain is unusual for early May, but warmer temperatures and clear skies are expected Monday into the middle of next week.
The National Weather Service also issued a flash flood watch through 8 p.m. for the Cuyama and Antelope valleys, as well as the Los Angeles, Ventura and Santa Barbara county mountains.
In the Inland Empire, a flash-flood watch through 9 p.m. affects the Apple, Lucerne and Coachella valleys, as well as the mountains of Riverside and San Bernardino counties.
The agency reported there is potential for slow-moving thunderstorms and possibly more than an inch of rain per hour in those areas.
