A fast-moving, wind-fueled wildfire swept into the city of Ventura early Tuesday, burning 45,500 acres, destroying homes and forcing 27,000 people to evacuate.
Gov. Jerry Brown declared a state of emergency in Ventura County on Tuesday morning.
"This fire is very dangerous and spreading rapidly, but we'll continue to attack it with all we've got," Brown said. "It's critical residents stay ready and evacuate immediately if told to do so."
The state is sending resources to help with firefighting efforts. Ventura County officials have asked the state for eight fixed-wing firefighting aircraft to help douse the flames, said Ventura County Sheriff's Sgt. Kevin Donoghue.
At least 150 structures — including at least one large apartment complex and the Vista Del Mar Hospital, a psychiatric facility — were consumed by flames, and many more were threatened.
