Heavy snow warning

A Heavy snow warning was a weather warning issued by the National Weather Service of the United States during times when a high rate of snowfall was occurring or was forecast. Generally, the warning was issued for snowfall rates of 4 inches (10 cm) or more in 12 hours, or 6 inches (15 cm) or more in 24 hours.

This warning was discontinued beginning with the 2008-09 winter storm season, replaced by the Winter Storm Warning for Heavy Snow.
