CALISTOGA, Calif.—California fire crews deploying water-dropping helicopters made a defensive stand on Friday against flames raging in the foothills of the Napa Valley wine region as forecasts called for a return of dangerous high winds and hot weather this weekend.
More than 2,500 firefighters were battling the Glass Fire, which broke out last Sunday near the resort community of Calistoga, some 75 miles (120 kilometers) north of San Francisco, and has already destroyed 248 homes or other structures.
