The National Weather Service (NWS) will be consolidating several types of cold season advisories and warnings starting this winter. The purpose of the change is to simplify and clarify communication and dissemination of winter weather hazards.
This change will combine a number of advisory and warning informational products into categories associated with similar hazards. For example, conditions last winter that prompted the issuance of separate winter weather, snow, and blowing snow advisories will simply be issued as winter weather advisories this winter. This consolidates seven different types of advisories to three, and six warning types to just four. Certain hazards will retain their own product names due to the uniqueness of their impacts.
Information on what hazards to expect will still be included and detailed at the start of each advisory or warning product.
There will be no change to the winter weather watch products.
