A historic wildfire in Texas continued to rage on Wednesday morning as firefighters work to contain the flames and survey damage.

The Smokehouse Creek fire, the second largest wildfire in Texas to date, has consumed more than 500,000 acres in Texas’ Panhandle area since it ignited on Monday.

The fire is currently at 0% containment, with several Texas counties still evacuated amid growing flames.

The Smokehouse Creek fire began at 40,000 acres on Tuesday, quickly swelling by Wednesday morning, CNN reported. The fire has burned through an area more than half the size of Rhode Island, CNN further reported.

The fire has largely spread given unseasonably warm temperatures and strong wind, propelling flames through dry grassy areas.

Mandatory evacuations were ordered for several Texas counties on Tuesday afternoon, as governor Greg Abbott issued a disaster declaration. Some counties have had their evacuation orderers lifted as of early Wednesday morning, the National Weather Service in Amarillo, Texas announced on X, formerly known as Twitter.

As of Wednesday morning, Texas officials are still determining the extent of damage as firefighters work to contain active flames. More than 4,000 homes in Texas are also without power as of Wednesday morning, poweroutage.us reported.

Texas department of agriculture officials have also warned that the wildfire may have a significant impact on the state’s agriculture industry.

“I am deeply concerned about the devastating wildfires raging through the Texas Panhandle. These fires not only threaten lives and property but also have a significant impact on our agriculture industry,” said the Texas agriculture commissioner, Sid Miller, in a post to Facebook.

The main facility that assembles and disassembles America’s nuclear arsenal was also forced to temporarily close on Tuesday as fires raged out of control in the area.

The Pantex site in Amarillo in north Texas reopened on Wednesday, according to an announcement on Facebook. Staff were instructed to return to work for normal shift operations after the plant updated that there was no fire at the plant site, NBC News reported.

“The Pantex Plant is open for normal day shift operations for Wednesday, February 28; all personnel are to report for duty according to their assigned schedule.”

Since 1975, Pantex has been the US main assembly and disassembly site for its atomic bombs. It assembled the last new bomb in 1991. In the time since, it has dismantled thousands of weapons. Pantex is located 30 miles (48km) east of Amarillo.
