Cooler Temperatures Aid California Fire Crews

Cooling temperatures and higher humidity on Monday gave firefighters some welcome relief as they waged an ongoing assault against a wildfire that had burned to the edges of a popular resort town in the San Gabriel Mountains.

The temperature at Wrightwood, at an elevation of about 6,000 feet, was expected to drop below 40 degrees.

Fire crews had spent the previous day cutting fire lines while battling erratic winds, which at times kept air tankers and helicopters grounded.

Officials warned the so-called Sheep fire, which had burned at least 7,500 acres, or nearly 12 square miles, and was 20 percent contained, still had potential to flare up and the town remained under mandatory evacuation orders.

Of most concern were the winds, which at times gusted up to 50 mph, then dropped to zero.

“It’s hard to get a handle on it,” Forest Service spokeswoman Barbara Duruisseau said. “The wind could be blowing one way one minute and another way the next.”

The fire had destroyed three homes in remote canyons but firefighters had kept it from encroaching into Wrightwood. Between 4,000 to 6,000 residents were ordered to evacuate.

Gov. Arnold Schwarzenegger declared a state of emergency for San Bernardino County, freeing up state resources to battle the fire.

The cause of the blaze was under investigation. It broke out Saturday near Lytle Creek, a small community surrounded by San Bernardino National Forest. Fueled by thick timber and brush, the fire pushed over hills and canyons by fast-moving winds.

Evacuation centers were set up at a high school in nearby Rialto and at the Victorville Fairgrounds.

In Arizona, strong winds kept some residents of the scenic northern Arizona city of Williams from returning to their homes Sunday as crews battled a prescribed burn that grew out of control and threatened part of the community known as the “Gateway to the Grand Canyon.”

Punky Moore, a Kaibab National Forest spokeswoman, said the Twin Fire scorched about 1,000 acres, or more than 11/2 square miles. It was burning forest undergrowth and ponderosa pines on Bill Williams Mountain.

“We had a little bit of cloud cover and that did help moderate fire activity, but we still had the winds,” she said. “That’s a concern. We just don’t want any fire outside of the lines.”

The forecast called for wind gusts as high as 26 mph Monday.
