Grand Teton issues Extreme Heat Warning

Grand Teton National Park posted this on their social media yesterday:
☀️ 𝗘𝘅𝘁𝗿𝗲𝗺𝗲 𝗛𝗲𝗮𝘁 𝗪𝗮𝗿𝗻𝗶𝗻𝗴: Plan Ahead and Stay Safe

An Extreme Heat Warning is in effect for Grand Teton National Park from noon Saturday, July 11, through 9 p.m. Monday, July 13. Temperatures are expected to reach around 100°F each day, creating dangerous conditions for outdoor recreation.

If you’re visiting the park:

• Plan hikes and other activities for early morning or cooler parts of the day.
• Carry more water than usual and take frequent breaks in the shade.
• Wear a hat and sunscreen, seek shaded areas, and know the signs of heat-related illness (https://www.cdc.gov/heat-health/about/).
• If you head onto the water to cool off, wear your personal flotation device (PFD).
• Avoid alcohol, which can speed up dehydration.

The safest way to beat the heat is to limit time outdoors during the hottest hours and spend time in air-conditioned or shaded spaces when possible.

A little extra planning helps keep your adventure safe. Stay cool, stay hydrated, and recreate responsibly.
