The National Weather Service is implementing new heavy snow criteria. This is being done across the contiguous United States. Changes are being done to eliminate non-meteorological discontinuities such as NWS office boundaries, adjust the length of time from a specific time frame to the overall event (not to exceed 48 hours), and to improve decision support services and communication. An interactive mapping of the criteria is available at this link: |
