Winter Weather Advisory - Types

Types

Because of the changes with the 2008-09 winter storm season, several varieties have been noted throughout the US.

• Winter Weather Advisory for Snow (Replaced the Heavy Snow Warning)
• Winter Weather Advisory for Snow and Blowing Snow (Replaced Blowing Snow Advisory, when conditions are not close enough to blizzard to warrant a Winter Storm Warning for Heavy Snow and Blowing Snow)
• Winter Weather Advisory for Sleet (Replaced the Sleet Advisory)
• Winter Weather Advisory for Sleet and Freezing Rain (or for Freezing Rain and Sleet) (When both the criteria for a WWA for sleet and an Freezing Rain Adviosry are met)
• Winter Weather Advisory for Freezing Rain (When the criteria for a Freezing Rain Advisory are met, and some other mentionable winter weather hazards prevent the issuance of a pure freezing rain product)
• Winter Storm Watch is given when a winter storm is likely to occur.
• Winter Storm Warning is given when a winter storm is moving into the area and that the public should take protective action.
• Also, the generic term, Winter Weather Advisory, may be used on its own to indicate that all three winter precipitation types are expected in moderate amounts.
