Firefighters continued to battle a wildfire in Southern California's Angeles National Forest that burned nearly 1,000 acres over the weekend and forced some people from their homes.

ABC 7 reported that the fire, dubbed the Sheep Fire, broke out Saturday amid scorching temperatures and bone-dry brush, and strong winds continued to fuel the flames. By Sunday afternoon, the fire had grown to at least 990 acres and was only 5 percent contained.

CNN reported that law enforcement is going door-to-door with a mandatory evacuation for Desert Front Road and Wild Horse Canyon.

By Monday morning, weather conditions had improved significantly, allowing crews to establish a more solid containment line around the blaze, assisted by helicopter water drops.

The cause of the fire remains under investigation.
