NWS Issues Grand Canyon Heat Watch After 3 Hiker Deaths as Temperatures Near 110F

3 articles · Updated · The Associated Press · Jun 21

Summary

  • Midday Monday through Tuesday, the National Weather Service expects Phantom Ranch temperatures to reach or exceed 110F, prompting an extreme heat watch for the Grand Canyon.
  • Three hikers — ages 67, 68 and 72 — died in separate heat-related incidents this month, leading the Park Service to strongly advise against midday hikes after a recent influx of heat illnesses.
  • Rim temperatures can run 20 to 25 degrees cooler than the canyon bottom, masking the danger for hikers who descend in milder conditions and then face a steep climb back in 105F to 110F heat.
  • Across the broader region, above-average heat and low humidity are also heightening fire danger; near Sedona, the Pocket Fire burned nearly 300 acres, triggered evacuations and shut about 30 miles of highway.
