What qualifies as a heat wave can vary greatly from region to region. In the northeast or Great Lakes region, a heat wave is generally considered to include three straight days of temperatures in the 90s or higher -- though folks in other parts of the country are used to different kinds of weather.
Should you find yourself in a heat wave, try to limit your time outside to the mornings and the evenings, when the air will be coolest. You'll also want to drink plenty of water throughout the day.
