Winter storm watch: The National Weather Service issues a winter storm watch when there is the potential for heavy snow or ice accumulation. The watch is typically issued at least 24 to 36 hours in advance. Criteria for the watch varies by location.

A winter weather watch means that the conditions suggest severe weather is possible and meteorologists have medium confidence that a winter storm could occur and bring heavy snow, sleet or freezing rain and cause significant impacts. When a winter weather watch is issued, you should be prepared for if/when the winter storm arrives.
