Cooler nighttime temperatures and calmer winds gave firefighters a break from hot, dry, gusty weather that fanned a wildfire that burned dozens of homes northeast of Colorado Springs and fueled three other major blazes in Colorado.

"That's going to give our firefighters a much better advantage, if there is such a thing," El Paso County Sheriff Terry Maketa said late Tuesday.

The Black Forest Fire in a heavily wooded residential area northeast of Colorado Springs burned 40 to 60 homes after it broke out Tuesday and prompted evacuations of about 2,300 homes, affecting about 6,400 people, Maketa said.

To the south, another blaze south of the Royal Gorge Bridge destroyed three structures near Canon City. Fires also sent plumes of smoke billowing up from southern Colorado and in Rocky Mountain National Park to the north.

At the Black Forest Fire, six helicopters and an air tanker were on the scene, Maketa said. The office of Rep. Doug Lamborn, R-Colo., said C-130 cargo planes were expected to be prepared to help fight the fire Wednesday.

The area is not far from last summer's devastating Waldo Canyon Fire that destroyed 346 homes and killed two.

"It's very, very reminiscent of what we experienced in Waldo Canyon," Maketa said.

However there were no immediate reports of injuries in the fires.

All of the fires moved quickly Tuesday, driven by record temperatures and strong winds. The conditions were making it difficult to build containment lines around the fire, and sparks jumped across them.

"Weather is not working with us right now, but our guys are giving it a heck of a shot," Maketa said.

In southern Colorado, the Bureau of Land Management said three structures have been lost in a fire on about 6 square miles near the Royal Gorge Bridge. Authorities evacuated Royal Gorge Bridge & Park, home of the soaring suspension bridge spanning the canyon across the Arkansas River.

A third wildfire in southern Colorado erupted Tuesday in rural Huerfano County. The Klikus Fire had burned an estimated 45 to 50 acres west of La Veta, prompting evacuation orders for about 200 residences.

The causes of those fires weren't immediately confirmed.

A fourth wildfire sparked by lightning Monday in Rocky Mountain National Park quickly grew to an estimated 300 to 400 acres Tuesday. No structures were threatened.

In the Colorado Springs area, George Gonzales, 74, and his wife stayed in their motorhome in the parking lot of a Red Cross shelter set up for evacuees from the Black Forest Fire. He said the two were eating lunch in town when his daughter got an alert on her phone about the fire and called them.

An officer let them go back home to retrieve their dogs, their motorhome and truck, and his heart medicine, George Gonzales said.

"Sure, we're worried, but we're hoping for the best," he said.

The Federal Emergency Management Agency has authorized federal funds to defray costs of fighting the Black Forest and Royal Gorge fires.

"There is nobody backing away and saying we're not going to attack this with everything that we've got," Gov. John Hickenlooper said late Tuesday.
