Two homes on a cul-de-sac in the 5500 block of Wembly Avenue were burned, and the entire mountainside just behind the homes was burned through. There were seven fire engines just on Wembly Avenue alone to provide structure protection.
The winds were so strong overnight that when firefighters were trying to put out flames at one home's roof, the winds were pushing the water back.
On Churchwood Drive near Kanan Road, two homes were severely damaged by fire.
Hundreds of Ventura County firefighters and eight air tankers were battling the flames on the ground and from above.

Plumes of thick, white smoke could be seen rising above the burn site as strong Santa Ana winds drove the flames amid red flag conditions.
The cause of the fires remain under investigation. No injuries have been reported.
