Firefighters have made progress in extinguishing some of the largest fires in the west, but in hot and dry conditions, the danger of sudden outbreaks and new fires still exists, which will bake up the dry landscape.
Nine fires burned more than 1.8 million acres In 12 states, the National Interagency Fire Center reported Monday morning, among which 23 states in Montana, some of which showed extreme fire behavior.
On Sunday, the agency released its monthly outlook, Forecast “significant wildfire potential” More than 95% of the western United States is in a dry state, and more than half of the area is in the two highest levels of drought conditions. It is expected that hotter than normal weather will continue into autumn.
But Oregon officials have good news on Monday to share news about the Bootleg fire, which has burned an estimated 413,762 acres (167,407 hectares) of land — an area larger than New York City — with a control rate of 84%.
Fire spokesperson Arnash said: “This reflects the days of ground work, and the staff have been able to strengthen and build additional containment lines.”
The Fremont-Winema National Forest has been burning since the fire caused by lightning on July 6. Firefighters initially believed that unless it rained heavily in autumn, they could not control it.
Some evacuation orders near the Dixie fire in California were also cancelled. The fire burned 248,820 acres in the past 19 days, with a control rate of 35%, but officials warned local residents to stay vigilant.
Authorities warned that the risk of an outbreak remains high due to unpredictable winds and extremely dry fuel. 67 houses and other buildings were destroyed in the fire, and another 9 were damaged. The cause of the fire is still under investigation, but it is believed to be caused by equipment from the utility company Pacific Gas & Electric.
It is expected that by the beginning of this week, there will be dangerous situations in Southern California. The temperature is expected to rise, the humidity is lower, and the onshore wind will increase.
In recent days, lightning has triggered two wildfires, threatening remote houses in the Shasta-Trinity National Forest. On Sunday, the evacuation warning for communities along the Trinity River remained.
Authorities said on Sunday that in Montana, a wind-driven wildfire destroyed more than a dozen homes, outbuildings and other structures. People were ordered to evacuate after the fire moved across the highway towards the community near Flathead Lake in the northwest of the state. Staff also fought the fires in northeastern Washington and northern Idaho.
Dry conditions and strong winds created dangerous fire conditions in Hawaii. Wind speed warnings were issued to Lanai, Maui and parts of the Big Island on Sunday.
A rapidly spreading wildfire on the Big Island of Hawaii spread to 40,000 acres, prompting a mandatory evacuation order. These orders-forcing thousands of residents to leave their homes-were cancelled on Sunday night. However, the authorities told residents to stay vigilant.
Hawaii County spokesperson Cyrus Johnasen (Cyrus Johnasen) said in a statement: “County officials require all residents in affected areas to go home only when absolutely necessary.” “Smog and other conditions may make those It is not safe for people with previous and potential respiratory illnesses to return.”
Local media reported that at least two houses were destroyed. The Hawaii Red Cross stated that the two community shelters are open to residents who cannot return home.
On Friday, Joe Biden and Kamala Harris Hold a virtual meeting with the governor Discuss the fire.
Biden said at the meeting: “We have had large and complex wildfires in multiple regions,” he pointed out that more help is needed, especially since the supply chain problems caused by Covid are still challenging. He added: “We cannot ignore how overlapping and intertwined factors such as extreme high temperatures, long-term droughts and super wildfire conditions affect this country.”
Historical droughts and recent heat waves associated with the climate crisis have made wildfires in the western United States more difficult to extinguish. Scientists say that the collapse of the climate over the past 30 years has made the region warmer and drier, and will continue to make the weather more extreme, and wildfires more frequent and destructive.
U.S drought Monitor reported last week that although strong monsoons have brought drought-relief rainfall to the southwest, extreme droughts continue in northern and northwestern California, and the most severe category of “abnormal drought” has been expanding.
Wildfires also affect further areas. With wildfire smoke lingering over most of the United States, many areas in the western and midwestern United States were under air quality warnings on Sunday.
Warnings have been issued in most areas of the northern Rocky Mountains of the United States, including parts of Colorado, Wyoming, Washington and Idaho. Further east, smoke from fires that burned into Canada triggered pollution warnings in Wisconsin, Minnesota, and Iowa.
Wildfires emit a large number of tiny smoke particles. Researchers say that if these particles are inhaled, they will have a direct and long-term impact on health. Children, the elderly, and people with underlying health problems are especially at risk.
Recent research shows that Smoke is more toxic than previously thought And can cause serious losses far away from the flame.
“No one is protected,” Dr. Mary Prunicki, a health researcher at Stanford University, told the Guardian in July. Her research shows that the number of hospitalizations associated with darkened air has increased dramatically, including strokes, heart attacks, and respiratory infections. “We don’t actually know what we were exposed to,” she added, “we should pay more attention to it.”
