Wildfires in the Texas Hill Country that have killed one man were threatening about 50 homes Saturday and have burned about 6,200 acres, officials said.

One fire in Kerr County, about 100 miles west of Austin, had burned about 1,100 acres and was putting about 50 homes at risk, said Texas Forest Service spokeswoman Traci Weaver.

In the same county, a fire that scorched 150 acres burned a camper-trailer and two mobile homes. That fire was about 75 percent contained, the forest service said.

Winds in the region were blowing at about 15 mph, and the humidity was expected to fall throughout the day, said Bill Runyon of the National Weather Service. Temperatures were in the mid-50s to low 60s, he said.

In Uvalde County, officials said a man found dead Friday next to his bulldozer was most likely killed by the fast-moving flames. He had been trying to protect his property from the fires.

Wildfires in Texas have burned more than a million acres since Dec. 1, including about 40,000 acres this week in the Panhandle, Weaver said. About 431 homes have been lost in fires since Dec. 27.
