Critical fire weather fuels largest blaze in the US

Key Points:

• A fast-moving wildfire, the Cottonwood Fire, is burning over 112 square miles in southern Utah, fueled by hot, dry, and windy conditions, leading the governor to declare an emergency and impose temporary fireworks restrictions through July 5.
• Firefighters face unprecedented challenges as high winds up to 45 mph and single-digit humidity ground air tankers and helicopters, allowing the fire to spread rapidly through treetops and cause severe damage, including to the Eagle Point ski resort.
• Red flag warnings and extreme fire weather conditions span from Idaho to southern Arizona and New Mexico, with utility companies preparing for power outages to reduce fire risks, including in Grand Canyon National Park.
• Experts warn that as long as hot, dry, and windy conditions persist amid ongoing drought in the West, the risk of extreme fire behavior remains high, especially with increased human-caused fire incidents.
• Authorities nationwide, including in Florida, urge caution with fireworks during the upcoming holiday, recommending professional displays to prevent additional wildfires amid critical fire weather conditions.
