Persistent, early-season heat is expected to continue through the weekend, raising wildfire risk across multiple U.S. regions and contributing to the rapid spread of the large Utah blaze.

The heat-driven fires and resulting smoke also compound ozone and particle pollution problems, worsening air quality and public-health impacts for millions while straining response resources.
