"It is very hot. Imagine how tough it is for the firefighters in heavy gear battling this fire," said KHOU 11 News reporter Marcelino Benito, who is at the scene.

There is no word on injuries at this time.

The objective is to contain the flames and stop them from spreading to nearby structures, said HFD spokesman Rick Flanagan.

The nearby American General building has been evacuated as a precaution.

The wind is creating another challenge for the hundreds of firefighters who are battling the flames.

"This couldn't have happened on a worse day," said KHOU 11 News Meteorologist Brooks Garner. "The wind is moving from the northwest at 15 mph with gusts over 20 mph."

West Dallas is closed at Montrose and traffic in the area is at a standstill.
