Inland areas and the mountains were hit hardest by the monsoon-like conditions.
There was scattered rain throughout the high desert in the morning, but no repeat of the problems caused by Saturday's storms.
"Trees were falling down, furniture was flying," said Victorville resident Larry Cochran. "I had my door closed, it blew open the door. It busted a window. It felt like a hurricane."
In Victorville, the downpours led to even more street flooding a day after a series of storm-related problems and power outages. About 2,500 homes were left without powers Saturday. Some residents may not get power back until Monday morning.
Strong winds snapped more than a half dozen power poles in one neighborhood. Lightning brought down at least one tree in a Victorville neighborhood.
The wild weather wasn't confined to the deserts. Rain, combined with heat and humidity, made for a sticky day in the Los Angeles basin.
From Glendale to Reseda, the rain was heavy at times before tapering off Sunday afternoon.
