Cal Fire Capt. Kendal Bortisser said the fire isn't like most fires that have hit San Diego and has been scattered in between homes and over hills.
Crews are expected to remain on the scene for the next couple of days. Triple-digital temperatures and wind gusts of 12-15 miles per hour fueled the fire's spread Friday, according to fire officials. High temps are expected to continue through Sunday.
"You add a little bit of wind to that, it's just going to increase the potential of the fire spreading quicker and moving faster," Capt. Bortisser said. "That's what we saw yesterday, the high temperatures, the dead dying fuel throughout, and a little bit of wind."
