Showers fell across Southern California Friday morning, prompting concern for residents in recent burn areas.
Forecasters expect the early season storm to lose most of its punch by the afternoon hours, but significant rain could fell in Los Angeles and Ventura Counties in the morning.
Once the rain had stopped, a rainbow appeared above the westside of Los Angeles Friday morning.
Video from Camarillo Springs, which dealt with damaging mudslides in 2014, showed light sprinkles falling as early as 4:30 a.m.
The storm was expected to bring a little less than an inch of rain to most places, however foothill and mountain locations could get one to two inches, according to the National Weather Service.
Forecasters warned thunderstorms could cause flash flooding and mudslides, especially in recent burn areas.
A flash-flood watch was in effect through Friday morning for recent wildfire burn areas in L.A. and Ventura counties.
A flash-flood watch for burn areas of the mountains of San Bernardino County is in effect through Friday afternoon. The area around the Blue Cut Fire, which burned 36,274 after starting in the Cajon Pass Aug. 16, could be affected.
Scattered showers are expected during the weekend and are in the forecast again on Tuesday, the weather service reported. Cooler temperatures will remain in the forecast through the middle of next week, with warming possible at the end of the the week, according to the agency.
