Los Angeles -- A wildfire in the mountains above Los Angeles has surged in every direction, going in a single day from a modest threat to a danger to some 10,000 homes.

The blaze nearly tripled in size in triple-digit heat Saturday, leaving three people burned, destroying at least three homes and forcing the evacuation of 1,000 homes and an untold number of people.

A slight drop in temperatures and an influx of fire crews from around the state were expected to bring some relief Sunday.

The flames crept down the slopes of the San Gabriel Mountains despite mild winds blowing predominantly in the other direction.
Mandatory evacuations were in effect for neighborhoods in Altadena, Glendale, Pasadena, La Crescenta and Big Tujunga Canyon.

"Today what happened is what I call the perfect storm of fuels, weather, and topography coming together," said Captain Mike Dietrich, the incident commander for the U.S. Forest Service. "Essentially the fire burned at will; it went where it wanted to when it wanted to."
