Showers and thunderstorms are possible in the San Diego region again on Sunday, but so far most areas have received less than a tenth of an inch, the National Weather Service reported.

“Another active day of showers and thunderstorms is forecast, with isolated flash flooding possible over most areas,” the weather service said, adding that dry conditions will develop late Sunday. Temperatures were expected to remain slightly below normal.

The highest rainfall was reported in Mira Mesa, with nearly a half an inch over the past 24 hours. Communities in East County saw more rain. Borrego Springs, El Cajon, Julian, Ramona and Valley Center reported between a quarter and third of an inch.

Wet roads challenged drivers. The California Highway Patrol reported 105 crashes in the region from midnight to 4 p.m. Saturday, compared to a 50-75 on a normal day.

The CHP reported flooding on State Route 79 near the Sunshine Summit volunteer fire station that closed all lanes on the highway for a time.

North of San Diego Countyy, strong rain was reported in the Coachella Valley. Nearly two inches of rain fell in the Snow Valley area near Big Bear Lake.
