HAZARDS

More information available on the HAZARDS DASHBOARD

The Experimental Enhanced Hazardous Weather Outlook is a decision support service that supports preparedness and response efforts prior to and during hazardous weather. This service provides decision makers with convenient access to potential weather hazard information by graphically depicting the risk of weather hazards out through seven days.

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  informationuser guide?
