"The sky was red, the wind was blowing really fast, and there were embers falling from the sky," said Simone Covey, 26, a mother of three who fled an apartment near Garden of the Gods park and was staying at a shelter. "I didn't really have time to think about it. I was just trying to keep my kids calm."
Wilma Juachon sat under a tree at an evacuation center, wearing a mask to block the smoke. A tourist from California, she was evacuated from a fire near Rocky Mountain National Park last week and, now, from her Colorado Springs hotel.
"I said I hope it never happens again, and guess what," Juachon said.
Constantly shifting winds challenged firefighters trying to contain the 24-square-mile Waldo Canyon blaze and extinguish hot spots inside the city's western suburbs. The National Weather Service reported 60-m.p.h. winds and lightning above the fire Wednesday afternoon.
"It won't stay in the same place," said incident commander Rich Harvey.
About 3,000 more people were evacuated to the west of the fire, Teller County authorities said Wednesday.
Meanwhile, the White House said President Obama would tour fire-stricken areas of Colorado on Friday and thank firefighters battling some of the worst fires to hit the American West in decades.
City Police Chief Richard Carey said Obama's visit to Colorado, considered a key battleground state in the presidential election, would not tax Carey's already-strained police force. Gov. John Hickenlooper said he expected the president to sign a disaster declaration that would allow for more federal aid.
The full scope of the fire remained unknown. So intense were the flames and so thick the smoke that rescue workers weren't able to tell residents which structures were destroyed and which ones were still standing. Steve Cox, a spokesman for Mayor Steve Bach, reported that at least dozens of homes had been consumed, though he had no precise figure.
Indeed, authorities were too busy Wednesday struggling to save homes in near-zero visibility to count how many had been destroyed in what is the latest test for a drought-parched and tinder-dry state. Crews also were battling a deadly and destructive wildfire in northern Colorado and another that flared Tuesday night near Boulder.
Carey said officials had no plans to release the numbers of homes destroyed - insisting residents have a right to be told first, in private.
FBI spokesman Dave Joly said federal investigators were working closely with local and state law enforcement to determine if any of Colorado's fires were deliberately set or resulted from criminal activity. He did not elaborate.
Colorado Springs Fire Chief Rich Brown said his personnel heroically saved many homes in the midst of the firestorm. The strategy: protecting houses adjacent to those in flames to prevent a domino effect, and then racing to the next suburban hot spot, a technique he called "triage." Federal firefighters worked with U.S. Army bulldozer crews from nearby Fort Carson to create perimeter lines.
The Waldo Canyon Fire burned about 10 acres along the southwest boundary of the Air Force Academy campus. No injuries or damage to structures were reported.
The Red Cross struggled to accommodate victims at its shelters, with space enough for perhaps 2,500 people. Most evacuees were staying with family and friends.
