About the Live U.S. Winter Weather Tracker

The Live U.S. Winter Weather Tracker from Orbis Weather brings together current winter weather information in one place, helping you monitor snow, ice, freezing conditions and outbreaks of extreme cold across the United States.

The tracker is designed to provide a quick overview of changing winter conditions, including National Weather Service watches, warnings and advisories. During active winter storms, visitors can use the interactive maps and alert filters to identify areas affected by snow, freezing rain, ice, frost, dangerous wind chills and extreme cold.

Tracking Snow, Ice and Extreme Cold

Winter weather conditions can change rapidly. Forecast snowfall totals, precipitation type and the location of the rain-snow line may shift as new observations and forecast model data become available. Check the tracker regularly when a winter storm threatens your area.

The interactive winter weather map can also be used to examine broader weather patterns across the United States and follow the development and movement of major storm systems. The live alert section helps highlight active winter weather products as they are issued and updated.
