After over a week of below-average temperatures across the central US, ice coverage has accelerated across the five Great Lakes.
Just over three weeks ago, the Great Lakes' ice coverage was at an all-time historical low. Now, thanks to the arctic outbreak, their ice coverage has rebounded.
For example, on Lake Erie, the percentage of ice cover on the lake was at 2.66% on Jan. 27, but as of Feb. 18, it's up to 81.69%.
This lake, which is the second smallest out of the five, has seen the fastest increase in ice cover.
The smallest lake, Lake Ontario, has also added ice cover in recent weeks. In just two weeks, coverage rose from 2.59% to 20.63%. Lake Ontario doesn't get as icy in the winters as Lake Erie because it is a deeper and, therefore, warmer lake.
The remaining three lakes, Superior, Michigan, and Huron, have seen at least a 20 percentage point increase these past two weeks.
