Western wildfires bring poor air quality across US: In Oregon, firefighters made progress over the weekend on the Bootleg fire, which extended to 646 square miles and grew 84% from Friday.
Elsewhere, authorities canceled evacuation orders for Dixie Fire in Northern California and another in the Big Island of Hawaii.
Despite the good news, with unpredictable winds and extremely dry fuel in the west, officials have warned that the risk of fires is high in the next few days. In addition, thunderstorms in many areas can provide welcome rainfall, and storms can also cause flooding.
Wildfires erupt across the west, leaving barren areas of vegetation prone to flash floods, especially during heavy rains.
The National Weather Service said flash flood clocks were in operation in the mountainous areas of seven western states from Montana to New Mexico.
Nearly 22,000 firefighters and paramedics are battling 91 wildfires covering 2,813 square miles in the western states, the National Intelligence Fire Center said.
There are more than 390 square miles of Dixie Fire Mountains in California, where 42 homes and other buildings were destroyed. Fires were reported in 35% of the areas on Monday, and many evacuation orders and warnings were lifted.
Dry conditions and strong winds formed for dangerous fire conditions in Hawaii. Sunday air advice was issued for parts of Lanai, Maui and the Big Island.
A fast-moving wildfire on a large island in Hawaii has risen to 62 square miles, prompting evacuation orders and forcing thousands of residents out of their homes. Those orders were lifted Sunday evening, but officials told residents to be vigilant.
“This is the biggest fire that has ever happened to us in Hawaii County,” said Big Island Mayor Mitch Roth Communications Director Cyrus Jonassen. “We want people to be safe but don’t forget that this is an emergency.”
Unlike the blazing fires in the western United States, two houses were destroyed in the fire. Hawaiian fires erupt over large grasslands on the dry sides of the islands and are usually much smaller than mainland fires. Although Hawaii has a humid, tropical climate, there is usually no risk of large fires, and fires can change frequently as climate change-related weather patterns intensify.
Hawaii County Fire Chief Kazuo Todd said winds were likely to rise Monday.
“Our current wind forecast shows wind patterns between 18 and 20 mph, with winds up to 40 mph,” Todd said Sunday night, “so throughout the evening our crew will work to build fire breaks with dozers and backburns, this temporary lift on mandatory evacuation current weather It needs to be strengthened because of the circumstances. “
In Montana, wind-driven wildfires destroyed 20 structures, including several homes, the Lake County Leader reported. A mandatory evacuation notice was issued Sunday morning as Boulder jumped the so-called highway fire. The blaze rose to more than one square mile Saturday night and was 0% under control.
Meanwhile, air quality warnings for smoke were in effect Monday for northwest, Arizona, Colorado, Wyoming and the Upper Middle East, the National Weather Service said.
Wildfires emit huge amounts of microscopic smoke particles, which researchers say can be harmful if inhaled and lead to immediate and long-term health problems. Children, the elderly and people with underlying health conditions are particularly at risk.
