SAN DIEGO — Heavy rains fell across San Diego County Thursday with motorists encountering a series of flooded roadways as they braved the Thanksgiving storms.

The rainfall -- expected to pelt the county into Friday-- led the National Weather Service to issue flood, wind and beach hazard warnings, with more than an inch reported in some areas of the county.
