An IBM facility and Muriel Wright School have been evacuated due to the threat of the wind-driven fire, as well as Girls Ranch. The Bernal Intermediate School is being used as a support facility.
SJFD says about 120 firefighters are battling the blaze, trying to keep it away from heavy fuels.
They're worried if they don't get good containment, it could spread to several hundred acres.
Crews have Heaton Moor Drive blocked off as the firefight continues. Aerial assistance and smoke are easy to see from the area.
