Thunderstorms developing over Southern California mountains have triggered flash-flood warnings in northwestern Ventura County and central Santa Barbara County.

The National Weather Service says radar indicates strong and nearly stationary thunderstorms producing heaving rain across the warning area Friday afternoon.

Flash-flood watches are posted for other mountain areas between Los Angeles County and Santa Barbara County as well as the Antelope and Cuyama valleys due to an unstable air mass. The condition is expected to last into the night.

The watch area excludes the Santa Monica Mountains, but NWS Los Angeles reported Friday evening thunderstorms were moving across the San Gabriel Mountains.
