Did Fritz say it was going to be like this?

That unexpected rain you probably heard pelting your windows has inspired the National Weather Service to issue a flash flood warning for Central L.A. County until 8 p.m. [Update: the NWS originally had this warning until 7 p.m. but it has been extended]

"Very heavy rainfall has been confirmed" along Aliso Canyon Rd. in the San Gabriel Mountains a few miles Southeast of Acton, the weather service reported at 5 p.m., noting rainfall of over two inches in one hour.

Mud cascaded into homes near Oliver Street and Cactus Avenue, spilling into some swimming pools in Moreno Valley, reports City News Service.  About 20 Riverside County firefighters were attempting to rescue people stuck in a car near the intersection.

Meanwhile Riverside County is under a flash flood watch until 8 p.m where flash flooding was reported in San Timoteo Canyon between Redlands and Moreno Valley.

The rain couldn't come at a worse time for commuters as it began to fall right as rush hour was starting.

For surfers and other beach-goers things may get gnarly as there's a high surf advisory for Southern California through Sunday evening.

Isolated showers and thunderstorms are expected through 11 p.m. tonight, but strangely, some residents are embracing the precipitation.

So funny how we appreciate rain so much here in LA like its raining ice cream!We all amazed lol. It's been months
