Hail and rain fell and lightning struck in multiple areas of Southern California Thursday afternoon, adding a wild, stormy edge to an oppressive and continuing heat wave.
Beginning about 3 p.m., severe thunderstorm warnings were issued in multiple area of the Inland Empire, including Lake Elsinore, Wildomar, Riverside, Fontana, Rialto and Moreno Valley. A flash-flood warning was in effect through 7 p.m.
Around 6 p.m., lightning prompted the evacuation of beaches in Santa Monica.
KTLA viewers sent the station video of hail and rain pounding their neighborhoods. In Wildomar, a fierce storm knocked a patio chair into Bernardo Flores’s sliding glass door, he said. He captured video of an intense downfall of hail.
The temperature dropped from 108 degrees to 69 degrees when the storm went through Wildomar, the National Weather Service’s San Diego office said. Multiple power poles were down in the area.
Showers and thunderstorms quickly developing across the LA Basin. Look for brief heavy rain, small hail and gusty winds with cells. #LArain

Burbank, meanwhile, hit 108 degrees, breaking a 2007 106-degree record for the date.
