SAN DIEGO (KGTV/CNS) - A last round of rainfall will douse San Diego County Thursday, and it’s expected to be the heaviest amount of precipitation of the week.
10News Meteorologist Megan Parry’s forecast calls for most of the heavy rain falling in the North County through mid-morning. By about 11 a.m., the rain will make its way south and drench the San Diego region.
Drivers are being urged to use caution on the roads Thursday, with the downpour leading to a slower-than-usual evening commute.
