Evacuation warnings were issued shortly after 2 p.m. on Monday because of a growing brush fire near the intersection of Ted Williams Parkway and Pomerado Road in Poway.
Cal Fire and Poway Fire are at the scene of the fire, which has reached 2 acres in size and is threatening structures.
Crews were fighting the blaze with two helicopters, two air tankers and an air attack plane.
Because of the wind direction, the potential evacuation area stretches southwest of the intersection.
A temporary evacuation point is located at Abraxas High School, 12450 Glen Oak Road in Poway.
