A pickup that went over the side of Highway 18 near Crestline started a fire that grew to 15 acres early Friday, but a heavy response from firefighters prevented the flames from spreading along the mountain road.



Windy and dry conditions contributed to the initial spread of the vehicle fire, according to fire officials.



"We have some extremely unusual weather," said John Miller, of the U.S. Forest Service. "It's the right formula to start a wildland fire."



The fire was at 15 acres early Friday. About 400 firefighters were attacking the fire, according to Miller.



"Our biggest concern is once we get some sunlight and things start to heat up and the winds increase," said Miller. "That's why we've committed 400 firefighters so early in the game."

Highway 18 was expected to remain closed until about 10 a.m.

The driver suffered minor injuries. One firefighter suffered an ankle injury.

Red flag warnings are in effect for much of the region. Expect dry, hot and windy conditions Friday afternoon.
