VENTURA, Calif. - The largest and most destructive wildfire in Southern California has grown to 140 square miles and fire officials say the worst may be yet to come.
 
The 90,000-acre fire burning in Ventura County northwest of Los Angeles has swept through ridges and canyons to the sea and Santa Ana winds that drove it are expected to return with a vengeance overnight.
 
State fire director Ken Pimlott says winds that eased in the afternoon could return with gusts up to 80 mph Thursday that would make it impossible to fight the fire.
 
Dozens of homes have burned since the blaze erupted Monday. Nearly 1,800 firefighters and a fleet of aircraft are fighting the flames but the blaze is only 5 percent contained and an estimated 12,000 buildings are in danger.
