A fast-moving brush fire north of Los Angeles has forced the evacuation of some 250 homes

The Los Angeles County Fire Department says the blaze broke out in the Stevenson Ranch foothill community Saturday afternoon.

It quickly chewed through 450 acres of dense dry brush amid high temperatures and winds gusting up to 25 mph.

More than 200 firefighters aided by water-dropping aircrafts are working to create a perimeter around homes that are being threated. Aerial photos showed the flames came to the property line of a ridgetop home that was covered in fire retardant.

Fire Inspector Gustavo Medina said the fire is burning close to Interstate 5.
