The Oklahoma Forestry Service told CNN the fires burned 400,000 acres, and prompted Gov. Mary Fallin to declare a state of emergency for 22 counties.

Officials in four other states said that 400,000 acres were destroyed in Kansas, 325,000 in the Texas Panhandle and 30,000 in Colorado — not to mention the 6,000 acres burning in the Florida swamps near Naples that resulted in mandatory evacuations.

Wildfires have forced evacuations in Texas, Oklahoma, Kansas and Colorado.

Firefighters injured

As many as five firefighters were injured while fighting another fire near Amarillo, Texas. Several blazes merged into one massive fire reportedly 12 to 15 miles across, according to Potter County Sheriff’s Office Capt. John Coffee.

The Texas A&M Forest Service is monitoring two major fires that remain active in the Texas Panhandle.

The largest of the two is the Perryton fire, which is more than 300,000 acres wide and only 5% contained. The fire, which is located in Ochiltree and Lipscomb counties, has destroyed two homes.

The other, the Dumas Complex fire, covers 25,000 acres and was 90% contained Tuesday evening.

The Texas A&M Forest Service and the National Weather Service Storm Prediction Center forecast that winds, which help stoke the wildfires, will subside on Wednesday.

Elevated fire conditions will return to the area on Thursday, Friday and Sunday, according to the Forest Service.

Gov. Greg Abbott activated state resources to combat the wildfires, according to a statement from his office.

One dead in Kansas

Kansas Gov. Sam Brownback said a man died from smoke inhalation in Clark County after getting out of a semitrailer truck he was driving.

“We’re not out of the woods, by any means,” Brownback said at a news conference where he urged residents to stay home if they didn’t have to travel.

“Yesterday was just a particularly incredible day for the state. We saw fire, floods, fail, tornadoes, straight line winds and dust,” he said.

The Kansas fires have accelerated rapidly throughout the day. According to Catherine Horner, spokeswoman with the state Division of Emergency Management, the fires in Clark County have consumed more than 350,000 acres — or nearly 60% of the county.

The fires have destroyed 30 homes and compromised bridges, Horner said, but it’s now at least 50% contained.

Horner told CNN that the fire in Reno County has forced 10 to 12 thousand people to evacuate. Crews went to homes and structures in the area looking for victims. The Kansas National Guard has lent four Black Hawk helicopters to the firefighting effort for water drops.

She also said the fire spread today to Comanche County, where 500 people had to be evacuated.

One fire-related death in Oklahoma

In Oklahoma, a 63-year-old woman died of a heart attack while fighting wildfires alongside her husband in Harper County, according to Dale Spradlin, Director of the state’s Department of Emergency Management.

He told CNN that 125,000 acres were burning in his county alone. The fires destroyed one “inhabited structure,” some barns and “a big hog production complex.”

“It’s 15 to 16% humidity,” Spradlin said. “It’s just like a powder keg out here. A good static charge will start a fire right now.”

An update from the Oklahoma Department of Emergency Management said that eight fire-related breathing complications had been reported to hospitals in the area.

More than 185,000 acres had burned in a fire in Beaver County, and fire departments in Payne County responded to five separate fires throughout the day, according to the update.

Fire conditions were not expected to improve through Tuesday night, according to a press release from Gov. Mary Fallin’s office.
