The National Weather Service office in San Diego issued a flash-flood warning on Friday afternoon for parts of East County after heavy thunderstorms developed over the mountains.

The warning, in effect until 3:30 p.m., covers Alpine, portions of Interstate 8, Pine Valley, Descanso, Guatay, the Viejas Indian reservation, Japatul Valley, Skye Valley, Boulder Creek and the Captain Grande Indian reservation.

“The latest radar forecast shows additional isolated to scattered showers and storms developing this afternoon across portions of SoCal. If you encounter any of these storms expect heavy downpours and frequent lightning,” the weather service said in a tweet.

The storms were producing .75-inch hail and wind gusts of up to 60 mph, according the weather service warning.

“The flooding risk from thunderstorms will be highest over the mountains and lower deserts. Thunderstorms will be diminishing by sunset this evening,” the weather service said.

Drivers were advised to turn around when encountering flooded roads as most flood

deaths occur in vehicles.
