Fire crews from the Los Angeles County Fire Department and the U.S. Forestry Service are continuing to battle three blazes in the hills surrounding Los Angeles which have burned over 500 acres since July 25.

The Owen Fire in Topanga Canyon in the Santa Monica Mountains is currently 25 acres and 30 percent contained, according to the Los Angeles County Sheriff’s Department at 9:26 p.m. on Wednesday.

The Los Angeles County Fire Department originally reported the Owen fire—which ignited near Topanga Canyon and Santa Maria Road—had burned around 50 acres as of 3 p.m. on Wednesday, which it has since accurately updated.

Currently, no evacuation orders have been issued, and the blaze has only prompted the closure of Topanga Canyon Boulevard from both directions, according to the California Department of Transportation.

The fire was first reported at 2:34 p.m. on Wednesday by the Los Angeles County Fire Department.

A 421-acre blaze dubbed the Agua Fire is 50 percent contained in the Angeles National Forest in Santa Clarita as of  8:20 a.m. July 27, according to the U.S. Forest Service.

There has also been no evacuation called for the fire, but Soledad Canyon Road between Agua Dulce Road and Crown Valley Road is closed, the forestry service reported.

City News Service reported one firefighter is being treated for minor injuries, in that blaze.

The Agua Fire was reported mid-day on Tuesday as an estimated 4 acres in Soledad Canyon, according to the Los Angeles County Fire Department, before it spread into the Angeles National Forest.

Firefighters continued to battle the flames amidst a heat advisory from the National Weather Service.

Crews are also in the middle of a clean-up effort after the Victor Fire, also in Santa Clarita, consumed 70 acres and is 10 percent contained, according to the California Department of Forestry and Fire Protection.

According to county fire department officials, the cause of the fire, which began around 3:30 p.m. is unknown.

One person was injured in that fire, according to City News Service.

“Conditions are grueling in the extreme heat but we continue to battle to keep our communities safe,” Los Angeles County firefighters wrote on Twitter Wednesday.
