The Antarctic is the area of the world where bomb cyclones are most frequently recorded. During 2017 the World Environmental Conservancy monitored more than 100 cyclones of this type on the icy continent without any reaching the intensity of the bomb cyclone that currently is forming off the east coast of the USA.

A pressure drop of 63 HPa is expected on the high seas east of Atlantic City, New Jersey at 1 pm (Eastern Standard Time) on January 4th, which will correspond to an extremely intense bomb cyclone, reaching a category 3 level (the maximum intensity) on the Bergeron scale. However, this will not be an all-time record as a pressure drop of 74 HPa previously was registered in the Sea of Japan.

The cyclone is expected to begin to intensify at dawn of January 4th, with its peak intensity projected in the afternoon. New York and Boston are expected to experience 30 HPa and 38 HPa pressure drops, respectively, Bergeron intensity 2. Temperatures will continue to fall by the end of the week, with Boston predicted to reach -5.8 oF on Sunday.
