Extreme Heat Warnings Persist Across Southwest, Impacting Millions
Millions of residents across the Southwest United States are under Extreme Heat Warnings this week as dangerously high temperatures continue to affect Arizona, California, Nevada, and Utah. According to the National Weather Service (NWS), temperatures in some areas are expected to exceed 120°F (48.9°C), with little relief during overnight hours as lows remain in the 80s and 90s. Arizona is among the hardest-hit states, with Phoenix and surrounding areas experiencing highs between 109°F and 118°F (42.8°C to 47.8°C). California's deserts and inland valleys, including Imperial County and the Coachella Valley, are also seeing temperatures as high as 119°F (48.3°C). Southern Nevada, including Las Vegas, and parts of southern Utah, such as Zion National Park, are similarly affected. Prolonged exposure to these conditions poses significant risks, particularly for vulnerable populations such as the elderly, children, and outdoor workers.
