What a winter storm warning means
A winter storm warning means a significant winter storm is happening or is expected within about 36 hours. It can be issued for heavy snow, a mix of snow and sleet, or snow with freezing rain. Each local National Weather Service office sets its own criteria based on what disrupts life in that area, so a few inches can trigger a warning in the South while northern and mountain offices use much higher snowfall totals.
