PHOENIX — With the forecast calling for temperatures between 105 degrees and 111 degrees, the National Weather Service has issued an excessive heat warning for parts of Grand Canyon National Park.

The warning will be in place from 8 a.m. Thursday through 8 p.m. Friday for areas below 4,000 feet in the Grand Canyon, including Phantom Ranch and Havasupai Gardens.

The National Park Service advises hikers to not go below the canyon’s rim while the heat warning is active. Officials want hikers to remember the further into the canyon one goes, the hotter it becomes.

Heat exhaustion, heat stroke, hyponatremia and death are some of the serious health risks that can come from hiking in extreme heat.

The National Park Service also warns that rescue efforts may be delayed due to limited staffing during the summer.

How can hikers prepare for the heat?

The National Park Service recommends drinking plenty of water, taking breaks and wearing loose-fitting cotton clothing to prepare for the heat. Wearing a hat and applying sunscreen is also advised.

Electrolyte replacement and salty foods, such as pretzels, crackers, and chips, will also help balance water intake during the excessive heat.

Hikers should also monitor others in their group for warning signs of heat stroke which can include fainting, confusion or an altered mental state.

A first aid kit with items such as hand sanitizer, Band-Aids, ace wrap, antibiotic ointment and blister care are additional helpful items to carry.

Can I still hike the Grand Canyon?

Yes, hiking the Grand Canyon is still allowed despite the heat warning, but those who still plan to hike are advised to take extra precautions and to be smart.

Hikers are suggested to start before 10 a.m. or after 4 p.m. and have a proper food and water intake. Bringing a flashlight with spare batteries is also suggested while hiking after the sun goes down.

Hikers are also advised to take breaks in the shade.
