"This fire literally started on the first day of our Santa Ana wind event, which it couldn't have started on a worse day," said Capt. Steve Kaufmann of the Ventura County Fire Department. "Last night, because we're still under the Santa Ana wind event, the fire activity increased overnight."
Kaufmann said the fire "blew up" very aggressively overnight into Santa Barbara County.
"If you're sitting on the 101 right now and you look up at the Camino Cielo ridgetop, you're going to be able to see fire that's crested the ridgetop that looks like it's heading down towards Montecito, Carpinteria, Summerland," he said.
An upwards of 4,000 firefighters have been deployed to the firefight.
"Please heed our warnings: the time for people to evacuate is not when we are trying to get our fire engines into the neighborhoods so if we do do an evacuation order, please make sure that you get out as soon as you can," he said.
