National Weather Service Regional Application and Perspective
During the last few Summer's, some of the Forecast Offices in Southern Region (SR) of the National Weather Service (NWS) have participated in testing a web-based heat/health warning system. The NWS currently uses minimum overnight temperatures and heat indices to decide when to issue heat watches or warnings. This new heat/health system is used as another guidance product for forecasters in making their decisions on when to issue a heat watch or warning. The heat/health test is based on demographics, history of mortality, and air mass synoptic meteorology.
