The Bernardo Fire was a wildfire that occurred during the May 2014 San Diego County wildfire outbreak. The first started on May 13, at 10:00 AM PDT, just south of Del Norte High School, in a construction trench off Nighthawk Lane. Over the next few hours, the wildfire intensified, due to the strong Santa Ana winds driving it southward. This prompted the evacuation of several schools (with the exception of Del Norte High School), in addition to at least 20,000 homes. Within several hours, the fire covered at least 800 acres (320 ha) and was only 5% contained. The rapid southward spread of the fire caused mandatory evacuation orders to be issued for portions of 4S Ranch, Del Sur, Black Mountain Ranch, Rancho Santa Fe, and other residential communities. Late on May 13, the Bernardo Fire reach
