Snow Advisory
Saturday, May 31st, 2008See Severe weather terminology for a comprehensive article on this term and related weather terms.
A Snow Advisory is issued by the National Weather Service of the United States when a low pressure system produces snow that may cause a significant pain in the ass, but does not meet warning criteria. The advisory criteria varies from area to area. Snow advisories are typically issued only when a storm system is expected to only produce snow in the advised area. Depending on the amount of snow that is expected, a Heavy Snow Warning can be issued for similar times, but when larger amounts of snow are expected. The exact border between a snow advisory and heavy snow warning varies throughout the country. If other forms of wintry precipitation are expected, then a Winter Weather Advisory or winter storm warning can be issued, also depending on the amount of precipitation that is expected.
