EXPERIMENTAL HEAT RISK MAP: Where will the heat be?
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
Aug. 8-13 Forecast:
This index is supplementary to official NWS heat products and is meant to provide risk guidance for decision-makers and heat-sensitive populations who need to take action at levels that may be below current NWS heat product levels.
