An explosive wildfire that has destroyed 80 homes and is threatening some 1,500 other residences in the central California mountains has grown to more than 12 square miles.

Fire officials said Friday that the blaze also has destroyed about 20 other buildings around Lake Isabella, a major outdoor recreation destination in the southern Sierra Nevada. It's not clear what those structures were.

Forecasters have posted warnings of very low humidity and gusty winds of up to 55 mph that could worsen the fire 35 miles northeast of Bakersfield.

Similar warnings are posted 150 miles south for mountains near Los Angeles.
