With the weather heating up, firefighters continued to focus on protecting critical infrastructure and recreation areas throughout the fire footprint. Crews were also working to identify and address pockets of fire and heat within interior portions of the burned area, along roads, and the Interstate 5 corridor, according to Cal Fire.

Hot and dry weather is expected through the weekend, with temperatures nearly triple-digits possible. On Sunday, there is a slight possibility of thunderstorms over the burn area.

The fire broke out last Saturday, prompting the evacuation of about 1,200 people from the Hungry Valley State Vehicular Recreation Area.

As of Friday evening, evacuation orders remained in place for the area south of Gorman Post Road, west of the 5 Freeway, east of the LA County line and north of Pyramid Lake. Evacuation warnings were in effect south of Pyramid Lake, west of the 5 Freeway, east of the county line and north of Templin Highway.

Cal Fire officials reported two structures destroyed in the blaze and one damaged. It was unclear if those were commercial or residential structures.

Authorities are officially reporting one injury from the fire, although no details were released.

The blaze is being battled by a unified command that includes the U.S. Forest Service, Angeles National Forest, the Los Angeles County Fire Department and Ventura County Fire Department. The Los Angeles County Sheriff's Department, California State Park Services, Los Angeles County Office of Emergency Management, Cal Fire and California Highway Patrol were also providing support.

"Crews continue making progress on the perimeter of the Post Fire ... allowing teams to focus more on the interior terrain," officials said in their Thursday morning update. "Crews continue seeking out isolated smoke and heat sources that produced small flare ups (Wednesday). Increased temperatures are expected over the next several days and into the weekend, which make these areas a priority."

The South Coast Air Quality Management District issued a wildfire smoke advisory for the Santa Clarita and Castaic areas, with northwesterly winds expected to push smoke from the fire southeast toward Santa Clarita, the San Fernando Valley and parts of the Angeles National Forest.

The SCAQMD advised people in the area to limit their exposure by remaining indoors with windows and doors closed or by seeking immediate shelter, avoid vigorous physical activity and to run their air conditioners or air purifiers.

"It's best to avoid using swamp coolers or whole house fans that bring in outside air," the agency said. Residents should also avoid burning wood in their fireplaces or firepits. And, if they absolutely must be outside, a properly fit N95 mask or P100 respirator may provide some protection.

The Post Fire started at about 1:45 p.m. Saturday at Ralph's Ranch and Gorman School roads, near the Golden State (5) Freeway, Los Angeles County Fire Department spokesman Craig Little told City News Service.

Some 1,542 personnel were involved in the firefighting effort.

The cause of the fire was under investigation.
