The US Forest Service announced that 3 firefighters died and 2 crew members were injured while responding to the Knowles and Gore fires on the Utah-Colorado border.
The agency, established early this year to accelerate wildfire fighting on public lands, said in a statement that it is in "deep sorrow" and will support the families left behind. It also said more details about the incident will be shared soon.
The fire season across the US is turning out to be very severe. According to officials, about 3 million acres (1.2 million hectares) have burned since the beginning of the year, a figure above the 10-year average. As of Sunday, at least 36 fires across the country remain "uncontained."
Utah Governor Spencer Cox banned the use of fireworks in the state ahead of the July 4th Independence Day holiday. In a post on his social media account, Cox said, "Today we mourn three heroes who made the ultimate sacrifice to protect communities and lives on the Utah-Colorado border."
Colorado Governor Jared Polis declared a state of emergency on Saturday, authorizing the deployment of the National Guard for firefighting. The Utah state government also warned that persistent drought and dry conditions are creating an "above-normal fire potential."
Arizona was also heavily affected by the fires. While flames continue south of the Grand Canyon and near Mount Kendrick, the area's electric company implemented a safety power outage on Saturday to reduce fire risk. This left some parts of northern Arizona without electricity.
The US National Oceanic and Atmospheric Administration (NOAA) notes that climate change has increased the likelihood of wildfires in recent years due to high temperatures, prolonged droughts, and dry conditions. As fires continue in the West, a record heatwave affecting Europe is expected to reach the eastern US on Wednesday.
