The hardest-hit community during Tuesday's blazes was Cross Plains, a West Texas ranching and oil-and-gas town of 1,000 people some 150 miles from Dallas. Cross Plains also lost about 50 homes and a church after the flames raced through grass dried out by the region's worst drought in 50 years.
Two elderly women there were killed after being trapped in their homes, said Sparky Dean, a spokesman for the Department of Public Safety. And in Callisburg, near the Oklahoma line, another woman apparently fell and broke her hip and could not get out of her home before it was destroyed, firefighters said.
No information was immediately available on the fourth death in Texas. A fifth person was killed in Oklahoma.
''We had a tornado here years ago and we thought that was devastating. This lasted for hours and hours,'' said Patricia Cook, a special-education aide whose Cross Plains home was saved by her 18-year-old son, J.D., and a friend. They saw the flames approaching the house from across a field and ran to save it.
''The fire was literally nipping at their heels,'' she said. ''He just picked up the hose and started watering things down.''
Elsewhere on her block, the front brick wall and part of a side wall were all that were left standing of the First United Methodist Church. The steeple lay across the ground. Ten other homes on her street also were reduced to charcoal.
Teresa Kennedy stood with her two children Wednesday outside her mother's home, destroyed in just minutes the day before. She and her seven siblings had left their home untouched since their mother's death six years ago.
''There's nothing,'' a tearful Kennedy said of her childhood home, a mix of brick and wood.
Most of the homes destroyed in Cross Plains were modest, working-class houses built during the 1930s and '40s. The fire spared a town landmark, the nearly century-old house - now a museum - of Robert E. Howard, author of the Conan the Barbarian books.
All together, the grass fires destroyed more than 100 buildings across Texas, including 78 homes, the state emergency management agency said. About 50 homes have been destroyed in Oklahoma, authorities said.
Wind gusting to 40 mph drove the flames across nearly 20,000 acres in the two states. At least 73 blazes were reported in Texas over two days, and dozens more broke out in Oklahoma.
Fires were still smoldering Wednesday in four Texas counties. One new fire broke out Wednesday in an isolated area of eastern Oklahoma but was quickly contained.
Severe drought set the stage for the fires, which authorities believe were started mostly by people shooting off fireworks, tossing cigarettes or burning trash in spite of bans imposed because of the drought. A fallen power line apparently started one Oklahoma blaze.
Rainfall this year in the Dallas-Fort Worth area of North Texas, where most of the fires broke out, is about 16 inches below the average of about 35 inches, the National Weather Service said.
