(PUEBLO COUNTY, Colo.) — The Oak Ridge fire burning near Beulah has increased to 787 acres with 0% containment as of Tuesday night, June 25.

The video above provided by Colorado’s Multi-Mission Aircraft (MMA) was taken on June 25, the bright light indicates areas of intense heat, and the brightest light on the west side shows new growth.

Officials said crews expected to see potentially significant fire growth in a press conference held on Tuesday afternoon. Community members who are under pre-evacuation should be prepared to leave if needed, and those near the evacuation zones should be prepared should an evacuation notice become necessary.

Fire crews will remain on scene for the rest of Tuesday evening and will continue to monitor the fire overnight.
