Lighting strikes caused power outages and sparked several fires as waves of brief thunderstorms moved across San Diego beginning in the afternoon Monday and continuing through the night.

“It was quite a light show out there this evening!” the National Weather Service office in San Diego said.

The agency counted 2,074 in-cloud and cloud-to-ground lightning strikes across Orange, San Diego and Riverside counties.

Cal Fire reported a small brush fire was sparked by lightning in Rainbow, and palm trees were struck and set ablaze in Bay Park.

Thousands of San Diego Gas and Electric customers experienced power outages on Tuesday morning, with parts of Old Town, Mission Hills and Hillcrest most effected. SDG&E said power would be back on in most areas by 3 a.m. Outages were also reported in Oceanside.

The storms produced relatively little rain, however, with total rainfall through 5 a.m. Tuesday reported at .72 inches at Fashion Valley, .64 at Lindbergh Field, .63 in Fallbrook, .60 in Escondido, .56 at Brown Field, .54 in Del Mar, .48 in Ramona and .43 in Julian.

“These storms have produced plentiful lightning and hail across the region, but overall have not produced much precipitation or winds,” the weather service said.

The rain will be followed by a cooling trend, with daytime temperatures likely 5 to 15 degrees below normal by Friday.
