Western heat wave shatters records, fueling evacuations and wildfires
A brutal Western U.S. heat wave pushed temperatures to record highs (Phoenix reached 116°F on Aug. 1, tying the city’s Aug. 1 record and coming close to the region’s all-time high) and spurred wildfire activity with evacuations in Spokane as the Old Trails Fire grew to about 2,300 acres. Southern California faced days of extreme heat with health warnings, while Montana’s Great Falls and Helena also set daily records. Officials warned about heat illness and urged limited outdoor activity, staying in air conditioning, and never leaving people or pets in cars. The extreme conditions are driven by a persistent high-pressure system and tropical moisture, with heat expected to ease later in the week.
