Grand Canyon National Park is issuing another warning about extreme heat after recent heat-related incidents that include the deaths of three hikers in the inner canyon. Multiple outlets report that the U.S. National Weather Service has placed the park on an extreme heat watch for midday conditions early next week.
The watch is scheduled to run from Monday morning through Tuesday evening, with the alert covering the most hazardous hours during the day. Forecasts indicate temperatures will exceed 100°F across lower-elevation areas of the park, with projections reaching around 110°F or higher at low-elevation locations such as Phantom Ranch. The guidance is based on expected weather conditions during the heat watch period.
The reports emphasize that park visitors face increased risk during peak heat and should follow park and weather guidance as conditions intensify. The warning comes as authorities continue to respond to the recent fatalities and assess how heat is affecting safety in the canyon’s lower areas.
