(CNN) -- A fast-moving wildfire in northern Texas has forced evacuations and destroyed 25 homes, fire officials said Tuesday.

The roughly 7,500-acre blaze was located about 50 miles west of Dallas-Fort Worth. Some 125 homes were evacuated, said Tom Berglund, spokesman for the Texas Forest Service.

"Obviously we don't have any containment on it. It's growing too fast," he said.

Berglund said air tankers were expected to assist firefighting efforts on Wednesday.

The cause of the blaze was not immediately clear.

Texas is currently battling its worst fire season in state history, according to officials. A record 3.5 million acres have burned since the start of the season in November.

Hot and dry weather, coupled with a lack of rain, have made conditions ripe for rapid fire growth.
