Determining Risk Level

Heat affects everyone differently. In order to better address heat risk and allow you to prepare for upcoming heat events, the National Weather Service (NWS) has developed the HeatRisk prototype forecast. The NWS HeatRisk forecast provides a quick view of heat risk potential over the upcoming seven days. The heat risk is portrayed in a numeric (0-4) and color (green/yellow/orange/red/magenta) scale which is similar in approach to the Air Quality Index (AQI) or the UV Index. In a similar way, it provides one value each day that indicates the approximate level of heat risk concern for any location, along with identifying the groups who are most at risk.
