What is Bomb Cyclone?

A bomb cyclone is a large mid-latitude storm that forms when a storm’s central pressure drops (i.e. “bombs out”), resulting in a rotating storm-like pattern. Often thought of as the equivalent of a winter hurricane, bomb cyclones typically form in cooler weather and intensify very quickly, resulting in heavy snow, rain, high winds and coastal flooding.
