The Mountain West region is facing unprecedented heat levels, with this winter being recorded as the second warmest in 131 years, according to federal scientists. The National Oceanic and Atmospheric Administration (NOAA) has reported that areas including Utah, Idaho, Nevada, Arizona, Wyoming, Colorado, and New Mexico experienced significantly above-average temperatures in February, with some areas hitting all-time highs. This warming trend is expected to continue into spring, potentially bringing historic heat to cities such as Las Vegas and Phoenix, where temperatures could reach around 100°F (38°C), leading to an early onset of extreme heat events.
