Visible satellite image of the Hudson Bay, Canada, storm on August 10, 2016 at 10:45 a.m. EDT, showing the occluded storm's "apostrophe" shape.
This extratropical storm intensified Tuesday over Hudson Bay, eventually reaching peak strength Wednesday, before weakening Thursday.
A visible satellite image showed the storm's classic mature phase as a cold occlusion, with relatively cool air completely wrapped around the low center, and a trailing band of clouds ahead of the cold front, resembling an apostrophe or the number 9.
