WILLIAMSON COUNTY, Texas (KXAN) — Fire crews in and around Williamson County have successfully responded to a wildfire near the DPS training facility southeast of Florence, with the National Interagency Fire Center reporting the fire is now 100% contained.

This followed an earlier update from the Texas A&M Forest Service, which said the fire had grown to 600 acres from its original 200-acre size. Williamson County officials said Wednesday crews hadn’t been able “to accurately map the size of the fire until Tuesday, July 5, due to difficult terrain.”

Williamson County Emergency Communications officials first received word of a structure fire off Pecan Branch around 2:30 p.m. Sunday. Williamson County ESD 5 — the Jarrell Fire Department — and the Florence Fire Department led initial response efforts.

An additional 175 firefighters from Austin, Round Rock, Georgetown, Hutto, Temple, Killeen, Salado, Bartlett and Liberty Hill’s fire departments responded to the fire. The Texas A&M Forest Service, Texas Department of Public Safety, Travis County Star Flight, the Williamson County Sheriff’s Office, Williamson County EMS and Williamson County Emergency Management also responded on scene.

As of 6:45 p.m., DPS communication personnel were notified the fire had reached the DPS training facility’s fence line near Florence. No injuries have been reported, and the cause of the fire is under investigation.

The Texas A&M Forest Service said the firefighting operation was interrupted by a drone that was seen flying above the flames.

The “unauthorized” drone caused firefighting aircraft to be removed from the area in case of a collision, the forest service explained.

As a result, members of the public have been asked not to fly drones in the area as crews continue fighting the fire.
