Blowing snow advisory

A Blowing snow advisory was issued by the National Weather Service of the United States when wind driven snow reduces surface visibility and possibly hampers traveling. Blowing snow may be falling snow, or snow that has already accumulated but is picked up and blown by strong winds. This advisory was discontinued beginning with the 2008-09 winter storm season, replaced by the Winter Weather Advisory for Snow and Blowing Snow. However, if the storm is judged to be dangerous by local forecasters, a Winter Storm Warning for heavy snow and blowing snow may be issued.

A similar bulletin is issued by Environment Canada's Meteorological Service of Canada but as a Warning.
