Wildfires continue to ravage the American West

Reading Time: 3 minutes

The U.S. Forest Service said it’s operating in crisis mode, fully deploying firefighters and maxing out its support system as wildfires continue to break out across the U.S. West, threatening thousands of homes and entire towns.

The roughly 21,000 federal firefighters working on the ground is more than double the number of firefighters sent to contain forest fires at this time a year ago, and the agency is facing “critical resources limitations,” said Anthony Scardina, a deputy forester for the agency’s Pacific Southwest region. 

An estimated 6,170 firefighters alone are battling the Dixie Fire in Northern California, the largest of 100 large fires burning in 14 states, with dozens more burning in western Canada. 

The fire began a month ago and has destroyed more than 1,000 homes, businesses and other structures, much of it in the small town of Greenville in the northern Sierra Nevada. 

The fire had ravaged more than 800 square miles (well over 2,000 square kilometers) — an area larger than the city of London — and continued to threaten more than a dozen rural and forest communities.

Gusty and erratic winds were threatening to spread the fire to Westwood, a lumber town of 1,700. Lightning could spark new blazes even as crews try to surround a number of other forest fires ignited by lightning last month.

Meanwhile, firefighters and residents were scrambling to save hundreds of homes as flames advance across the Northern Cheyenne Indian Reservation in southeastern Montana.

The blaze was still burning near the tribal headquarters town of Lame Deer, where a mandatory evacuation remained in place and a second fire was threatening from the opposite direction.

Smoke drove air pollution levels to unhealthy or very unhealthy levels in portions of Montana, Idaho, Oregon Washington and Northern California, according to Environmental Protection Agency air quality monitoring. 

An air quality alert covering seven Montana counties warned of extremely high levels of small pollution particles found in smoke, which can cause lung issues and other health problems if inhaled.

The fires near Lame Deer combined have burned 275 square miles (710 square kilometers) this week, so far sparing homes but causing extensive damage to pasture lands that ranchers depend on to feed their cows and horses.

Hot, dry weather with strong afternoon winds also propelled several fires in Washington state, and similar weather was expected into the weekend, fire officials said.

In southeastern Oregon, two new wildfires started by lightning Thursday near the California border were spreading through juniper trees, sagebrush and evergreen trees. 

Climate change has made the U.S. West warmer and drier in the past 30 years and will continue to make the weather more extreme and wildfires more destructive, according to scientists.

More than 6,000 square miles (almost 16,000 square kilometers) have been burned in the U.S. so far this year. That’s well ahead of the amount burned by this point last year, but below the 10-year average, according to the National Interagency Fire Center.
