MONTGOMERY COUNTY, TX --In Montgomery County, firefighters are battling an out-of-control wildfire. Winds gusting up to 25 miles per hour keep pushing the fire northwest along the Montgomery-San Jacinto county line. The Texas Forest Service says the fire started near Cut and Shoot and has grown to about 200 acre -- most of it inside the Sam Houston National Forest. "We have a large woods fire. A very windy dry day on Memorial Day and we have several crawler tractors that are working on the fire and several helicopters also," said Ralph Cullom of the U.S. Forest Service. Crews had the fire contained to 150 acres before the flames jumped the line Monday night. Firefighters are trying to cut a new line in front of the flames. The Forestry Service says it does not know how this fire started.
