SAN DIEGO—Flash floods inundated homes and overturned cars in San Diego on Monday as torrential rain swept through a large swath of the U.S., toppling trees and overflowing streets across California.
Early morning flooding hit the town of Guerneville, north of San Francisco, where a creek overflowed after more than 4 inches (10 cm) of rain fell in 24 hours. The local school district canceled classes for the day.
