I read a story that happened near where I live a few miles from West Hills, Calif (San Fernando valley) where a firetruck was on a dirt road fighting a fire when a fire swept up from below and went over them in seconds. The windows were blown out and one fireman on the other side of the truck facing away was burned. I personally saw a brush fire near Chatsworth Park North where smoke was going up a ravine from the bottom and instantly turned to fire as it got to the top.
