Firefighters wrestle with dozens of blazes

? Thunderstorms sparked as many as 75 wildfires in a wilderness area in far Northern California on Saturday as officials farther south got close to containing a blaze that destroyed several homes and forced thousands to evacuate.

Storms overnight Friday were responsible for the large number of fires in Shasta-Trinity National Forest, near Redding. Those fires range in size from less than an acre to more than 750 acres.

None immediately threatened homes, said Forest Service spokesman Michael Odle. Teams moved in Saturday on the two largest fires.

South of San Francisco, a fire that burned homes and closed a stretch of highway was 90 percent contained, said officials of the California Department of Forestry and Fire Protection.

Cal Fire expects the fire to be fully contained today. So far, it had charred 630 acres, or less than a square mile.

Evacuation orders were lifted Saturday, a day after roughly 2,000 people fled their homes.
