Temperatures are so hot at the Grand Canyon it might melt your shoes. 

Planning to visit the Grand Canyon anytime soon? You may want to take extra shoes, as park officials are warning of extreme heat that can melt your shoes.

The park shared the warning in a tweet earlier this week:

The high temperatures can melt the glue used to hold many shoes together, resulting in a precarious situation. Temperatures got so hot that an Excessive Heat Warning was issued by the National Park Service for elevations lower than 4,000 feet. Temperatures in the area reached as high as 113 degrees Fahrenheit.  

The National Park Service is urging special caution for all hikers during the summer months and reminds visitors that it is vital to be prepared when embarking on any hike into the canyon. Do not force fluids, and try to hike earlier or later in the day, avoiding the peak heat times of 10 a.m. through 4 p.m. The Grand Canyon National Park will experience increasing temperatures during the summer months and is expected to hit temperatures in the Inner Canyon in the triple digits for the next three months.

Rangers responded to multiple heat-related search and rescue calls just this past weekend.

"Every year, scores of unprepared hikers, lured by initially easy downhill hiking, experience severe illness, injury, or death from hiking in the canyon," said Grand Canyon National Park officials.

Hikers can experience heat exhaustion, heatstroke, water intoxication, hypothermia, sunburn, and severe dehydration if not properly prepared to hike in these kinds of conditions.

A good portion of the Western United States is experiencing a heatwave right now, and in northern and central California, temperatures are expected to reach 110 degrees Fahrenheit. Florida is also experiencing dangerously high meditators. Oh, and there's a Saharan dust cloud that's heading for the United States.

Whether you're hiking in the Grand Canyon or elsewhere, it's always wise to be prepared, plan ahead, have plenty of fluids, and not to overexert yourself. The high temperatures can be deadly, and rescue efforts may be hampered by the heat, weather conditions, lowered rate of rescue personnel, and more.
