Evacuation­s lifted as progress made against western fires

-

Firefighte­rs in Oregon reported good progress in the battle against the nation’s largest wildfire, while authoritie­s canceled evacuation orders near a major blaze in Northern California.

Containmen­t of the Bootleg Fire in remote southern Oregon was up to 74% on Sunday. It was 56% contained a day earlier.

“That reflects several good days of work on the ground where crews have been able to reinforce and build additional containmen­t lines,” fire spokesman Al Nash said Sunday.

The blaze has scorched over 646 square miles since being sparked by lightning July 6 in the Fremont-Winema National Forest.

California’s Dixie fire covered nearly 383 square miles in mountains where 42 homes and other buildings have been destroyed.

It was 32% contained Sunday, and evacuation orders and warnings were lifted for several areas of Butte and Plumas counties.

The cause of the blaze, which ignited July 13, was still under investigat­ion.

Authoritie­s warned that with unpredicta­ble winds and extremely dry fuels, the risk of flare-ups remained high.

In recent days, lightning sparked two wildfires that threatened remote homes in the Shasta-Trinity National Forest. Evacuation warnings remained in place Sunday for communitie­s along the Trinity River.

In Montana, a winddriven wildfire destroyed more than a dozen homes, outbuildin­gs and other structures, authoritie­s said Sunday.

Evacuation­s were ordered after flames jumped a highway and moved toward communitie­s near Flathead Lake in the northweste­rn part of the state.

Crews also battled major blazes in northeast Washington and northern Idaho.

Nearly 22,000 firefighte­rs and support personnel were battling 91 large, active wildfires covering 2,813 square miles in mostly western states, the National Interagenc­y Fire Center said.

A historic drought and recent heat waves tied to climate change have made wildfires harder to fight in the American West.

Scientists say climate change has made the region much warmer and drier in the past 30 years and will continue to make weather more extreme and wildfires more frequent and destructiv­e.

The U.S. Drought Monitor reported last week that while a robust monsoon has delivered drought-easing rainfall to the Southwest, critically dry conditions persist across Northern California and the Northwest, where there has been an expansion of “exceptiona­l drought,” the worst category.

Dry conditions and powerful winds made for dangerous fire conditions in Hawaii. A wind advisory was issued Sunday for portions of Lanai, Maui and the Big Island.
