The NWS said the area could see rainfall rates of up to 0.70 inches per hour along with thunderstorms, especially in the higher elevations of southern Santa Barbara County.
“Rainfall of this intensity can produce dangerous mud and debris flows near the burn areas,” the NWS said, noting that flash flooding and debris flows would particularly threaten communities near recent burn areas.
Santa Barbara County officials have issued mandatory evacuation orders for communities near the Thomas, Whittier, Alamo and Sherpa fire burn areas.
