When conditions are right, meteotsunamis may occur in many bodies of water around the world, including the Great Lakes. Many of us in the weather community aren’t familiar with them either. There were also a few other perturbations earlier in the night, likely caused by the front as it moved off shore, but the official time of the meteotsuanami is being reported as 10-10:12 p.m.
