WINTER STORM SEVERITY INDEX
The Winter Storm Severity Index (WSSI) is a utility to provide information on the severity of winter weather and potential societal impacts (travel conditions, etc). The WSSI does not depict official watches, warnings or advisories, and should always be used in context with official forecasts. The WSSI uses NWS forecasts and typically updates every two hours. Always check the creation and valid times. Need more regional information? user guide?
