Warnings of critical fire conditions blanketed much of the U.S. Southwest on Saturday, as crews in northern New Mexico worked to stop the growth of the nation’s largest active wildfire.
The 7-week-old fire, the largest in New Mexico history, has burned 1,272 square kilometers (491 square miles) of forest in rugged terrain east of Santa Fe since it was started in April by two planned burns.
Crews were patrolling partially burned areas and clearing and cutting containment lines, including primary ones near the fire as bulldozers scraped backup lines farther away.
The National Weather Service issued red flag warnings of critical fire conditions for parts of Arizona, Colorado, Kansas, Nevada, New Mexico, Oklahoma, Texas and Utah. Those conditions are a combination of strong wind, low relative humidity and dry vegetation.
Dry air, high winds
The return of drier and warmer weather with stronger winds posed a threat of increased fire activity over the Memorial Day weekend, prompting officials to urge the public to secure vehicle chains and to be careful with possible fire sources.
“The last thing we need right now is another ignition,” said Jayson Coil, an operations section chief.
Forecasts called for wind gusts up to 80 kph (50 mph), with critical fire conditions continuing into Monday, followed by more favorable weather later in the coming week, said Bruno Rodriguez, the fire management team’s meteorologist.
The strong winds could fan flames and cause the fire to jump containment lines and race forward, said John Chester, a fire operations manager.
“Imagine traveling in your car and the fire can outpace you. That’s the kind of extreme fire behavior that we’re talking about,” Chester said.
3,000 firefighters
Nearly 3,000 firefighters and other personnel were assigned to the fire, which was contained around 48% of its perimeter.
Initial estimates say the fire has destroyed at least 330 homes, but state officials expect the number of homes and other structures that have burned to rise to more than 1,000 as more assessments are done.
Elsewhere, 150 firefighters battled a wind-driven fire that burned 24 square kilometers (9 square miles) of grass, brush and salt cedar on the California side of the Colorado River about 22.5 kilometers (14 miles) southwest of Parker, Arizona.
The fire forced the evacuation of a recreational vehicle park after it started Thursday and was 44% contained Saturday, officials said.
The cause of the fire was under investigation.
