AZUSA, Calif. -- Two fast-moving brush fires continue to burn through dry brush in the Angeles National Forest above Azusa and Duarte early Tuesday morning.
The fires, dubbed the Reservoir Fire and Fish Fire, have burned a total of 5,400 acres and neither have been contained. The Fish Fire has prompted mandatory evacuations in Duarte and fire officials are considering issuing some for Monrovia.
California Highway Patrol officers received a call around 10:57 a.m. about a pickup truck going over the embankment of Highway 39 near the Morris Reservoir Dam. The truck caught fire, which officials believe may have sparked the blaze. The driver was pronounced dead at the scene.
The Reservoir Fire has burned about 2,400 acres, according to fire officials.

About 90 minutes later, the Fish Fire broke out above Duarte and quickly began to spread through the brush. It has burned about 3,000 acres, according to fire officials.
So far, the fires have not merged, fire officials said, but they are only a mile and a half apart. Hundreds of firefighters from multiple agencies are working to control the fires. One firefighter suffered heat exhaustion fighting the blazes amid triple-digit temperatures.
Water drops were continued overnight in an effort to keep the fires away from homes. About 600 residents in the Duarte and Bradbury area have been affected by the blaze and 400 homes were evacuated.
The weather is expected to cool down over the next few days, but Tuesday will still be hot with very dry conditions. Red flag warnings are still in effect until Tuesday night for Los Angeles County mountain areas of the Angeles National Forest, the Santa Monica mountains and the Ventura County mountain areas of Los Padres National Forest.
Evacuations ordered in Azusa and Duarte
Azusa police ordered evacuations for Mountain Cove, Rainbow Canyon Ranch and El Encanto. An evacuation center was set up at Duarte Community Center, 1600 Huntington Dr., and at Memorial Park, 320 N. Orange Ave.
For the city of Duarte, an evacuation order was issued for homes north of Fish Canyon between Encanto Parkway and Greenbank Avenue, Brookridge Road and Opal Canyon Road.
Officials later announced extended mandatory evacuations for areas north of Markwood Street between Westvale Road and Greenbank Avenue, areas north of Deerlane Drive between Greenbank Avenue and Mountain Crest Road.
Residents in the Mount Olive Drive area just northwest of Conata Street, including residents in the Spinks Canyon Road, Rim Road, Goldenmeadow Drive, High Mesa Drive, and Tall Pink Drive areas were also mandated to evacuate the area.
Large animals can be taken to the Hansen Dam Equestrian Center at 11127 Orcas Ave. in Sylmar, and small pets can be taken to Wonder Dog Ranch at 220 Taylor St. in Monrovia.
Though there were no mandatory evacuations in effect for Monrovia, officials urged residents east of Myrtle Avenue and north of Greystone Avenue to prepare for possible evacuations if winds change direction or increase in intensity.
According to Los Angeles County Fire Chief Deputy David Richardson, 320 structures were evacuated near Azusa and 450 structures evacuated in the Duarte and Bradbury area.
