SALT LAKE CITY — Utah officials have declared a state of emergency as the largest active wildfire in the United States continues to expand rapidly, creating dangerous conditions ahead of the busy Independence Day holiday.

The Cottonwood Fire has burned more than 112 square miles in southern Utah, forcing evacuations, damaging property, and threatening nearby communities. Strong winds, extremely dry vegetation, and soaring temperatures have complicated firefighting efforts, while aircraft operations have been limited by hazardous weather.

State leaders have also implemented temporary fireworks restrictions through July 5, aiming to reduce the risk of additional human-caused wildfires during one of the busiest holiday periods of the year. The National Weather Service has issued a rare "Particularly Dangerous Situation" warning for parts of Utah, highlighting the elevated wildfire threat.

Emergency management agencies are urging residents to remain alert, follow evacuation instructions where necessary, and avoid activities that could spark new fires. Smoke from the wildfire has affected air quality across portions of the western United States, while firefighters continue working to contain multiple active blazes across the region.

Authorities warn that continued hot, windy weather could allow fires to spread quickly in the coming days, making wildfire prevention a top public safety priority as millions of Americans prepare for July Fourth celebrations.
