The Cave Fire is creating some of the toughest firefighting conditions anywhere in the world, Los Padres National Forest Fire Chief Jim Harris said Tuesday.
Harris said the land is extremely dry not only because it's the end of the dry season, but also because several offshore wind events have dried the area out even more
Santa Barbara County Fire Battalion Chief Anthony Stornetta described it as "quite the firefight" as winds move up slope, down slope and across slope.
The cause of the blaze is unknown, Brown said.
Rain is heading to the region on Wednesday, which could help fight the fire. But the one to two inches of rainfall could also cause debris to flow in parts of coastal Southern California.
The Cave Fire also caused some power outages in parts of southern Santa Barbara County. The number of those without power was not clear.
Stornetta said Tuesday that the number-one priority is to get residents back home.
