Each USA National Weather Service Forecast Office issues some or all of the following heat-related products as conditions warrant.
NWS local offices often collaborate with local partners to determine when an alert should be issued for a local area. For instance, residents of Florida are much more prepared for 90 °F+ weather than residents in Alaska.
- Excessive Heat Outlooks: are issued when the potential exists for an excessive heat event in the next 3-7 days. An Outlook provides information to those who need considerable lead-time to prepare for the event.
- Excessive Heat Watches: are issued when conditions are favorable for an excessive heat event in the next 24 to 72 hours. A Watch is used when the risk of a heat wave has increased but its occurrence and timing is still uncertain.
- Excessive Heat Warning/Advisories are issued when an excessive heat event is expected in the next 36 hours. These products are issued when an excessive heat event is occurring, is imminent, or has a very high probability of occurring. The warning is used for conditions posing a threat to life.
The following article from the US National Weather Service (NWS) website with links to other NWS and EPA web pages, is worth repeating here also.

Heat is the number one weather-related killer in the United States, resulting in hundreds of fatalities each year.
In fact, on average, excessive heat claims more lives each year than floods, lightning, tornadoes and hurricanes combined.
In the disastrous heat wave of 1980, more than 1,250 people died.

Easy-to-use UGA temperature table may help reduce heat-related deaths of children in closed cars
Athens GA, USA — A team of researchers at the University of Georgia (UGA) has developed an easy-to-use table of vehicle temperature changes (in closed cars during hot weather) that may help public officials and media remind the public about the deadly consequences of vehicle-related hyperthermia in children.
