Rare summer thunderstorms roll through county

More than 1,000 customers lost power at one point

SAN DIEGO - Thunderstorms continue to threaten northern San Diego County Sunday and the National Weather Service has issued a flash flood warning for the rural area near Palomar Mountain as county residents dry off from rare summer showers that drenched the coastline.

"It was just all of a sudden someone turned on the shower or threw a bucket of water over our heads … it was just a downpour," said George Sharp, who was out walking with his dog. "Roo doesn't seem to mind it. She got groomed yesterday,so that kind of went by the wayside."

The NWS issued a flash flood warning shortly before 2:45 p.m. that lasts until 5:45 p.m. for the area near Palomar Mountain, where nearby Sunshine Summit received four tenths of an inch of rain in 10 minutes. The CHP reported that State Route 79 was closed in both directions at mile marker 46.5 for flooding.

It was the second flash flood warning the county received Sunday following a warning this morning that said flooding was possible from Camp Pendleton to San Ysidro.

As the storms rolled slowly through San Diego County drifting to the northwest, "Thirty lightning strikes were detected over and off the coast, with a gauge in Del Mar picking up .57 inches of rain," the NWS reported. Solana Beach received .29 inches and Mission Beach received .15-inches.

The sound of thunder and flashes of lighting rattled several Clairemont residents after lightning struck a palm tree in their neighborhood.

"All of a sudden, it was just a loud pop and real bright and it kind of scared me and I kind of stood up and stood back," said a neighbor.

Parts of the tree burned and fell on the ground. Fortunately, no one was hurt.

According to SDG&E, the storms knocked out power in at least five locations including Ocean Beach, Encinitas, Logan Heights, Torrey Pines and Mission Valley that left more than 1,000 customers without power.

The NWS reported cloud-to-ground lightning within five miles of Lindbergh Field that triggered lightning warnings for the airport, though a spokesperson at Lindbergh Field said flights were unaffected.

The isolated thunderstorms continued until about noon Sunday and left behind small pockets of flooding.

CHP reported flooding in the right-hand lanes of northbound Interstate 805 approaching Interstate 5 near Carmel Valley. Social media users posted pictures which appeared to show flooding on surface streets including North
Torrey Pines Road near the Torrey Pines Golf Course, Genesee Ave south of Centurion Square near University City High School and the 400 block of Santa Fe Drive approaching the I-5 onramp near the Vons shopping center.

Drivers had to inch through the intersection of Carmel Mountain and Sorrento Valley roads after standing water caused some flooding.
