LOS ANGELES (CNS) – Slow-moving thunderstorms may form this afternoon over the Antelope Valley and the San Gabriel Mountains in Los Angeles and Ventura counties, forecasters said.
“Any thunderstorm that does form will be capable of producing heavy downpours and flash flooding,” according to a National Weather Service advisory.
Downpours also may unleash debris flows, especially in areas denuded by wildfire, it said.
A flash flood watch will be in effect in the Antelope Valley and the San Gabriels through tonight. Thunderstorm activity will abate overnight but another round is likely in the same areas Saturday afternoon, according to the NWS.
The weather service forecast partly cloudy skies today and highs of 81 in Avalon; 84 at LAX; 85 in Newport Beach and on Mount Wilson; 92 in Long Beach, San Gabriel and downtown L.A.; 93 in Anaheim; 95 in Palmdale; 96 in Pasadena; 97 in Lancaster; 98 in Burbank; 101 in Saugus; and 103 in Woodland Hills.
