A surprise summer thunderstorm soaked Southern California on Sunday, stranding drivers in their cars and knocking out power to thousands.
As much as three inches of rain fell on the deserts of southwest San Diego county, prompting the California Highway Patrol to close roadways in Anza-Borrego Desert State Park after a number of motorists were stranded in flooded washes.
Nearly two inches of rain fell on Escondido in a span of about an hour, and lightning knocked out power to over 14,000 customers for about five hours.
The National Weather Service issued flash flood warnings for both the northern coasts and the southwest desert in San Diego County.
The storms are the result of tropical moisture from the low pressure system that was recently Hurricane Dean.
