Heat Waves

How hot is dangerously hot?

  • The National Weather Service has devised a Heat Index which is given in degrees Fahrenheit. The Heat Index is a measure of how hot it really feels when relative humidity is added to the actual air temperature.

​

  • The National Weather Service will initiate alert procedures when the Heat Index is expected to exceed 105° F to 110° F for at least two consecutive days.

​

  • Children, elderly, and other sensitive individuals may have less ability to tolerate high temperatures.  If working outside, make sure you follow the tips below on staying safe.

How can I stay safe during a heat wave?

  • Strenuous activities should be reduced, eliminated, or rescheduled to the coolest time of the day.

​

  • Drink plenty of water while the heat wave lasts. Avoid alcoholic beverages and caffeine. They interfere with your body's ability to cool itself.

​

  • Try to get out of the heat for at least a few hours each day. If you can't do this at home drop in to a cool store, restaurant, or theater to keep your exposure time down.

​

  • Cool or at least ventilate your home; avoid enclosed rooms. Moving air, even if not cooled, helps cool you by evaporating your sweat.
