Snow Advisory

Snow Advisory

A Snow Advisory is issued by the National Weather Service of the United States when a low pressure system produces snow that may cause significant disruption , 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. For example, one inch of snow will constitute the advisory in Florida, while up to 5 inches will do so in New England. 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.
