STINNETT, Texas (AP) — Firefighters battling the largest wildfire in Texas history face increasingly difficult weather conditions on Saturday.

The Smokehouse Creek Fire that began Monday has killed at least two people, left a charred landscape of scorched prairie, dead cattle and destroyed as many as 500 structures, including burned-out homes, in the Texas Panhandle.

The National Weather Service issued a red flag warning for the entire Panhandle from late Saturday morning through midnight Sunday after rain and snow on Thursday allowed firefighters to contain a portion of the fire.
