YARNELL, Ariz. - An elite team of 19 firefighters died Sunday while trying to protect themselves under fire-resistant shields from a fast-moving wildfire in Yarnell, Ariz., according to officials.
Authorities believe the wildfire began in Yarnell, about 90 miles northwest of Phoenix, Friday with a lightning strike and spread to at least 2,000 acres Sunday amid triple-digit temperatures, low humidity and windy conditions. As of 3 a.m. this morning, the Yarnell fire had tripled in size and is now 6,000 acres, according to Arizona incident commander Mike Reichling.
Eighteen of the victims were from the Prescott Granite Mountain Hotshots, fire officials said. It's unclear where the other victim was based.
"We grieve for the family. We grieve for the department. We grieve for the city," Prescott Fire Chief Dan Fraijo said at a Sunday night news conference. "We're devastated. We just lost 19 of some of the finest people you'll ever meet."
The 19 deaths is the greatest loss of life for firefighters in a wildfire since 1933, according to the National Fire Protection Association.
It is also the deadliest day for U.S. firefighters since 9/11, when 340 died.
"19 lives were lost, brave men who gave their lives in defense of friends, neighbors and perfect strangers," Arizona Governor Jan Brewer said Monday.
"We can never fully repay the sacrifices made by your loved ones," the governor added a moment later.
The team was known as a "hotshot" crew and was deployed to attack the fire line with tools.
"Hotshot" crews are elite firefighters who often hike for miles into the wilderness with chain saws and backpacks filled with heavy gear to build lines of protection between people and fires. They remove brush, trees and anything that might burn in the direction of homes and cities.
"They're not the people that have engine companies and large trucks. These are the core of firefighting where they're right there in the middle of the incident," Fraijo said.
Fraijo said the crew killed in the Yarnell fire worked other wildfires in recent weeks in New Mexico and Arizona.
He added that the firefighters had to deploy the tent-like structures when "something drastic" occurred.
"One of the last fail-safe methods that a firefighter can do under those conditions is literally to dig as much as they can down and cover themselves with a protective -- kind of looks like a foil type, fire-resistant material -- with the desire, the hope, at least, is that the fire will burn over the top of them and they can survive it," Fraijo said.
The Prescott-based crew never had to use shelters during a wildfire, according to a 2012 profile in a Cronkite News Service report.
Reichling, the incident commander, said half of the 500 structures in Yarnell have been destroyed by the "radical weather." Most of Yarnell's 700 residents have been forced to evacuate.
"We have fires throughout the state right now. We have the winds that change. That's what happened today and caused this tragedy," he said.
Evacuee Don Mason said, "I don't know if my home's standing or not, but from what I've heard, most of Yarnell has burned to the ground. So it's been tough."
About 200 firefighters are fighting the wildfire, which has also forced the closure of parts of state Route 89. None of the fire is contained.
President Obama, who is traveling in Africa, released a statement early this morning, calling the 19 firefighters "heroes" for putting "themselves in harm's way to protect the lives and property of fellow citizens they would never meet."
Former U.S. Rep. Gabrielle Giffords expressed her shock on Twitter, calling the death of the firefighters "absolutely devastating news."
Monday, Fraijo told reporters the deaths of the firefighters are under investigation. He said they hope the tragedy can be learned from, to teach future firefighters how to protect themselves.
"We have to recognize that there is still a fire going on and there are still men and women on the fire line doing their job as they always do," said Prescott Mayor Marlin Kuykendall.
