Flash Flood Watch for Redlands, Loma Linda + Mountains Through 11p Friday

A flash flood watch for an area including Redlands, Loma Linda and the San Bernardino Mountains was expected to remain in effect through 11 p.m. Friday.

Forecasters said storm potential was due to "an upper level low . . . with a very moist and unstable air mass in place" over Southern California that should begin clearing by early Saturday.

"Scattered thunderstorms are forecast over all the mountains . . . deserts . . . and Inland Empire," the National Weather Service advised.

Thunderstorms late Thursday night and early Friday morning produced heavy rainfall in some areas with amounts between two-thirds of an inch to more than 2 inches in a short period of time, according to the Weather Service.

"Excessive runoff from heavy downpours may cause rapid filling and overlfowing of normally dry washes and small creek," the Weather Service advised. "Potential impacts include flash flooding and minor debrsi flows in small creeks and streams  . . . roadway intersections . . . and other low-lying or poorly drained areas."
