Extreme Heat and Elevated Wildfire Risk in California and Arizona
California and Arizona are experiencing extreme heat conditions this week, with temperatures exceeding 100°F (38°C) in some areas. The National Weather Service (NWS) has issued heat alerts, while the National Oceanic and Atmospheric Administration (NOAA) warns of significant wildland fire potential across the Southwest. Red flag warnings have been issued in California, Arizona, and Utah, indicating critical fire weather conditions due to dry air, gusty winds, and primed vegetation. NOAA's recent climate assessment highlights above-normal wildfire risks for May in parts of the Southwest, northern Plains, and southeastern coastal regions. The National Interagency Fire Center (NIFC) reports that fire activity is already above average, with 1,848,210 acres burned as of April 30, 2026, and nearly 62% of the U.S. in drought conditions.
