Shannon Orand looks at some melted coins Monday in Texroy, Texas, following a fire that consumed his home late Sunday. Wildfires continued to rage across nearly 700,000 acres in Texas on Monday and have been blamed for 11 deaths.

BORGER, Texas — Airtankers dumped flame retardant as firefighters struggled to fight blazes raging across more than 1,000 square miles of Texas, the aftermath of what officials called the worst single day in the state's wildfire history.

The Department of Public Safety late Monday attributed four new deaths to the fires, bringing the death toll to 11. Nine firefighters have been injured and about 1,900 people evacuated as the flames raced through dry grasses and fields.

"We share in the grief of those who have lost family members and loved ones, and we offer our prayers," Gov. Rick Perry said. "Throughout this wildfire season, communities in our state have shown strength and resolve that are uniquely Texan."

Eleven fires were burning across an estimated nearly 700,000 acres Monday, up from 663,000 over the weekend. State fire crews fought more than 160 blazes in one 24-hour period.

Though winds also died down Monday, fire crews struggled with the effects of Sunday's fires, which broke the previous one-day mark of 326,000 in 1996, said Forest Service spokesman Warren Bielenberg.

The size of the scorched area easily eclipsed the 455,000 acres that burned in December and January, when the governor declared a disaster.

Fire evacuee Jennifer Orand returned Monday to find her mobile home in the Hutchinson County community of Texroy burned to the ground.

"I just started crying," said Orand, 27, who lives with her husband, Shannon, about 40 miles northeast of Amarillo. "You hear all the time that people think it will never happen to you. I never thought I'd say that myself."

A series of rural fires stretching through Collinsworth, Wheeler, Carson, Hutchinson, Donley and Gray counties, scorched some 652,000 acres by Monday night, and were still burning early today, the Texas Forest Service reported.

Another wildfire in Childress and Cottle counties reached 45,000 acres, the Texas Forest Service said.

The National Weather Service in Amarillo said dry conditions were expected to persist today but firefighting efforts could be aided by lighter winds.

After a deadly Sunday in which four people from Oklahoma died in a crash on a smoke-shrouded highway and three people died in fires near Borger, the Department of Public Safety late Monday attributed four more deaths to the fires.

Trooper Daniel Hawthorne said four bodies found late Monday were discovered near a car in a ravine north of Miami in Roberts County. Authorities were investigating the deaths, but Hawthorne said they appeared to result from a large grass fire in Roberts County.

The rash of fires prompted the evacuation of eight towns: Hoover, Lefors, McLean, Miami, Old Mobeetie, New Mobeetie, Skellytown and Wheeler.
