Wildfires ravaging Southern California have destroyed a total of 96 homes and 213 other buildings, according to the San Bernardino Fire Department.

Nearly 1,600 firefighters are battling the Blue Cut wildfire east of Los Angeles. On Friday, the San Bernardino National Forest announced that 37,000 acres have burned and the fire has been contained to 26 percent.

Gusty winds between 30 and 50 mph are expected to continue in the area, and warnings of fire weather and excessive heat are stretching from Southern California to the Pacific Northwest due to the winds and low humidity, with some parts of Southern California have less than 5 percent humidity.
