PRODUCT DESCRIPTION - The experimental WSSI is created through the use of Geographic Information Systems (GIS) by screening the official National Weather Service (NWS) gridded forecasts from the National Digital Forecast Database (NDFD) for winter weather elements and combining those data with non-meteorological or static information datasets (e.g., climatology, land-use, urban areas). This creates a graphical depiction of anticipated overall impacts to society due to winter weather. The underlying structure of the experimental WSSI allows it to potentially use other meteorological datasets as inputs (e.g., deterministic or ensemble model output) to create additional guidance products that cover periods beyond those covered by the NDFD. The experimental WSSI provides a classification of the overall expected severity of winter weather using the following terminology: "none," "limited," "minor, "moderate," "major," and "extreme." PURPOSE - The experimental WSSI has been developed to have a two-fold focus. The first is for use as a tool to assist NWS operational forecasters in maintaining situational awareness of the possible significance of weather-related impacts based upon the current official forecasts. The second is to enhance communication to external partners, media and the general public of the expected severity of potential societal impacts due to expected winter hazards and their distribution. AUDIENCE - The experimental WSSI is intended for use by 116 NWS Weather Forecast Offices (WFOs) and Weather Prediction Center (WPC) staff as an enhancement to decision support services, as well as for use and evaluation by NWS partners, the media and the general public.
