LOS ANGELES (KTLA) — Parts of the Southland saw some dramatic thunder and lightning early Friday, as a storm dropped rare summer rain on areas of Los Angeles and Orange counties.
As of 9 a.m., National Weather Service radar showed pockets of rain in Riverside, Palm Springs and Big Bear, and on Catalina Island.
Thunderstorms remained possible through Friday as a moisture surge moved northwest over Southern California.
“Thunderstorms are expected to be slow-moving and will have the potential to produce heavy rainfall, especially across the Antelope Valley” and the interior mountains, according to the NWS. The rain “may cause flash-flooding, especially in steep terrain or in and below recent burn areas.”
A trough of low atmospheric pressure was expected to arrive during the weekend, bringing drier conditions and cooler air.
