SAN DIEGO — Record-setting rainfall and driving winds lashed the San Diego area Thursday, prompting widespread flooding, fallen trees, mudslides and other storm-related hazards across the soaked region.
The intensity of the downpours prompted the National Weather Service to issue a countywide flash-flood watch effective through Thursday evening. A wind advisory will remain in effect in the local mountains until 4 a.m. Saturday.
As the rains intensified, the San Diego County Office of Education announced that Vallecitos Elementary School in Rainbow would be closed for the day.
Additionally, campuses in the Pine Valley-area Mountain Empire Unified School District were slated to close an hour early due to flash flooding, and students at Santa Margarita and Stuart Mesa elementary schools on the grounds of Camp Pendleton were to be let out prior to their usual end of classes due to road closures and potential flooding.
Moderately severe overflows along the San Diego River were expected until early Friday in the area of Fashion Valley and Mission Valley malls, as well as on the Santa Margarita River in the North County.
