One of the most impressive time lapses I've seen in a long time. This is from WGN-TV Hancock camera earlier this week (February 21). Look how quickly the ice opens up over Lake Michigan as the winds shift and the temperatures rise. If this doesn't cause you to rethink walking on the ice I don't know what will.
Cracks in the ice are VERY common especially this time of year. Fluctuations in air temperature, wind direction and intensity drive the shifting ice making it more unstable.
Ice coverage across the Great Lakes have reached their peak and are now falling.
LAKE SUPERIOR: 51% on Feb 19th
LAKE MICHIGAN: 335 on Feb 18th
Lake Erie, the shallowest of the lakes is showing significant ice breakup.

The ice movement forecast through early next week.
