An '''ice storm warning''' is a hazardous weather statement issued by the Weather Forecast Offices of the [[National Weather Service]] in
the [[United States]] which indicates that  [[freezing rain]] produces a significant and possibly damaging accumulation of [[ice storm|ice]] on surfaces.  The criteria for this warning vary from state to state, but typically an ice storm warning will be issued any time more than {{convert|1/4|in|mm}} of ice at peak is expected to accumulate in an area, else a [[Winter Weather Advisory|freezing rain or drizzle advisory]] is issued; in some areas, the criterion is {{convert|1/2|in|mm}} instead.<ref>{{cite web|title=Ice storm warning|url=http://www.weather.gov/glossary/index.php?word=ice+storm+warning|work=Glossary - NOAA's National Weather Service.|access-date=17 May 2011|author=National Weather Service}}</ref>

Prior to October 2017, a [[freezing rain advisory]] or '''freezing drizzle advisory''' was issued when a small amount of icing was possible.

In [[Canada]], a '''freezing rain warning''' has the same meaning.
