The NWS HeatRisk is an experimental color-numeric-based index that provides a forecast risk of heat-related impacts to occur over a 24-hour period. HeatRisk takes into consideration:
How unusual the heat is for the time of the year
The duration of the heat including both daytime and nighttime temperatures
If those temperatures pose an elevated risk of heat-related impacts based on data from the CDC
This index is supplementary to official NWS heat products and is meant to provide risk guidance for those decision makers and heat-sensitive populations who need to take actions at levels that may be below current NWS heat product levels.

Hot days can affect anyone. If you are pregnant, are a child or teen with asthma, or have a heart condition or other chronic health conditions, heat can make your health worse.

The Heat-Related EMS Activation Surveillance Dashboard, created in partnership between the HHS Office of Climate Change and Health Equity and the DOT National Highway Traffic Safety Administration, uses nationally submitted Emergency Medical Services (EMS) data to track EMS responses to people experiencing heat-related emergencies in the pre-hospital setting.
