Ice Concentration Forecast Guidance
This ice concentration animation was created from the latest LSOFS forecast guidance in the Lake Superior. The forecast guidance is for the next 120 hours of ice concentration as simulated by LSOFS when it is forced by meteorological parameters that are predicted by the National Weather Service models.
