Western US Faces Peak of Dangerous Heatwave, Elevating Wildfire and Air Quality Concerns

A dangerous heatwave is peaking across the Western U.S., prompting Extreme Heat Warnings for Arizona, California, Nevada, and Utah. Forecasted Mojave Desert temperatures could reach 43.3–48.9°C (110–120°F), with record highs already noted in Reno and Salt Lake City.
