RESERVE, N.M. – A massive wildfire in the New Mexico wilderness that already is the largest in state history spread in all directions Thursday, and experts say it’s likely a preview of things to come as states across the West contend with wind, low humidity and tinder-dry fuels.

The erratic Gila National Forest blaze grew overnight to more than 190,000 acres as it raced across the area’s ponderosa pine-covered hills and through its rugged canyons.

More than 1,200 firefighters are at the massive blaze near the Arizona border, which has destroyed a dozen cabins and eight outbuildings, fire information officer Iris Estes said.

Experts say persistent drought, climate change and shifts in land use and firefighting strategies mean other western states likely will see similar giant fires this season.

“We’ve been in a long drought cycle for the last 20 years, and conditions now are great for these type of fires,” said Steve Pyne, author of “Tending Fire. Coping with America’s Wildland Fires” and a life science professor at Arizona State University.

“Everything is in line.”

Agencies in New Mexico, Colorado, Arizona and other western states are bracing for the worst. Many counties have established emergency telephone and email notification systems to warn of wildfires, and most states have enlisted crews from nearby states to be ready when the big ones come.

“It’s highly likely that these fires are going to get so big that states are going to need outside resources to fight them,” said Jeremy Sullens, a wildland fire analyst at the National Interagency Fire Center.
