The southwestern United States, an area already experiencing worsening drought conditions and elevated fire risk, can expect a massive heatwave heading into this weekend. Temperatures will range anywhere from 15-25 degrees above normal across the West, breaking daily temperature records and even challenging some all-time June temperature records. Some locations in the lower deserts of California and Arizona may surpass 120 degrees.
Higher energy demand for cooling across the region will put added stress on the power grid, which may lead to some power cuts. The prolonged and widespread nature of the heat will also further strain infrastructure and residents.
Staff working outdoors for a prolonged period of time should exercise extreme caution. Drink plenty of fluids and wear light-colored clothing if possible. In some of the hottest locations in the Southwest, any outdoor activity can prove life-threatening in a short period of time.
Relief may be on the way as the heat is expected to slowly ease late this weekend into early next week.
