Extreme heat conditions can affect anyone and everyone. Special populations are often affected more than others, such as, the elderly, young children and infants, and people with health conditions. Extreme heat is when the temperature and/or humidity is significantly higher than average for a specific location.

Heat warnings and watches
The National Weather Service will forecast an Excessive Heat Warning within 12 hours of the following temperature: a heat index of at least 105°F for more than 3 hours per day for 2 consecutive days, or a heat index above 115°F for any period of time. An Excessive Heat Watch is issued when the heat index is above 105ºF (41ºC) during the day along with the low temperature of 80ºF (27ºC) or higher at night for two consecutive days. The Heat Index (HI) is a measurement of how hot it really feels when the Relative Humidity (RH) is added to the actual air temperature.
