SAN DIEGO — Scattered thunderstorms are expected this afternoon over the mountains and deserts with a Flash Flood Watch in place for certain areas of San Diego County.

The Flash Flood Watch is in effect for the county’s mountains from noon Tuesday through Wednesday evening. Forecasters say scattered, strong thunderstorms could produce heavy rainfall that may lead to dangerous flash flooding.

Forecasters say San Diego’s deserts have a 30% chance of afternoon thunderstorms with highs from 102 to 107. At the coast, mostly cloudy weather is expected with patchy fog in the morning becoming mostly sunny this afternoon with highs 73 to 78.
