DALLAS (AP) — Gray weather with occasional showers along a stationary front was giving firefighters a hand in tightening the cordon on a pair of wildfire complexes in West and North Texas.

The Texas Forest Service reports the Possum Kingdom Complex is 50 percent contained Sunday after burning 166 homes and two churches and 200 square miles of grass and woodland 70 miles west of Fort Worth.

The two-week-old Trans-Pecos Complex of wildfires in West Texas is about 75 percent contained Sunday after destroying 23 homes and two commercial structures around Fort Davis a week ago.

Two firefighters have died of injuries suffered while fighting the fires. No evacuations were reported Sunday.

An East Texas Piney Woods wildfire 90 miles northeast of Houston is 85 percent contained after burning 7,100 acres.
