A flash flood watch was issued for recent burn areas in Los Angeles and Ventura counties on Saturday as showers were expected to move over southwest California throughout the day and into Sunday, according to the National Weather Service.
Widespread showers with a slight chance of thunderstorms were anticipated, and by 7:30 a.m. rain began to fall across Santa Barbara and western San Fernando Valley.
Showers will become “numerous” on Saturday, the weather service warned.
Precipitation levels were expected to reach .33 to 1 inch in coastal and valley areas, and half an inch to 1.5 inches in the foothills and mountains.
“Significant snow accumulation” was also expected to fall at 7,000 feet, with snow falling as low as 6,500 Saturday night.
People were advised to drive cautiously, and a flash flood watch was issued for recent burn areas where there was a potential for mud and debris flows.
The watch was expected to remain in effect through Sunday afternoon.
In Glendora, the alert status near the Colby Fire burn area -- which claimed nearly 2,000 acres in January 2014 -- was elevated to yellow, meaning residents should remove vehicles, trash bins, and other obstructions from the street, and respect rain-related parking restrictions, the local police department posted on Facebook.
