More than 1.600 firefighters fought the blaze on land and from the air in the Santa Ynez Mountains, west of Santa Barbara.

More than 1.600 firefighters managed to stop the further growth and 78 percent is under control, authorities said.

They are threatening approximately 400 structures.

A 0.6-hectare conflagration lit outside a fire protection line in the North West corner of the fire was quickly contained by firefighters, using bulldokers and hand lines on the ground and using water to put out the flames.

On Sunday, few fires were left, and Fire Service members kept concentrating on ramping up containment.

Cooler temperatures had been forecast for Sunday but gusts of 32 mph were still expected for the region, authorities said.
