Thursday’s storm dumped a significant amount of rain on Santa Barbara County as it moved over the region. Rainfall rates of up to half an inch per hour were measured in some areas, prompting the National Weather Service to issue flood advisories for Santa Barbara and Ventura counties. Forecasters also issued a flash-flood watch for all the most-recent burn scars in Los Angeles, Riverside and Orange counties through 3 p.m.
