Martinez Lake, Arizona, recorded 110°F on Thursday, breaking the US record for the hottest March temperature ever. This occurred during a late-winter heatwave affecting the southwestern US. The previous record was 108°F, set in Texas in 1954 and tied in California earlier in the week. Numerous locations in California also reached 108°F, and Thermal, California, was forecast to potentially tie the new record. The heatwave caused record highs in cities including Phoenix and Las Vegas, with temperatures 20-30 degrees Fahrenheit above normal for March. Phoenix experienced its earliest triple-digit temperature day, and hiking trails were closed due to heat illness risks.
