Firefighters say calm, cool morning weather has dampened a Kern County wildfire that's burned 25 structures. The blaze about 10 miles south of Tehachapi still threatens 150 homes but fire spokesman John Buchanan says he sees mainly smoke and embers Thursday morning. However, the area about 70 miles north of Los Angeles gets gusty afternoon winds and Buchanan says firefighters are expecting gusts of up to 14 mph. The 1,400-acre fire began Tuesday and is 25 percent contained. Firefighters expect to have it fully surrounded by Friday.
