The “bomb cyclone” about to wallop the East Coast has been referred to as a bombogenesis by meteorologists — leaving many scratching their heads. It’s also left Americans still digging themselves out of a foot or more of snowfall from last weekend’s Winter Storm Fern, worrying about being buried by another few inches.

Amid unrelenting frigid temperatures, a bomb cyclone off Long Island's Atlantic coast is expected to bring up to 3 inches of snow, high winds and beach erosion, particularly to the East End, forecasters said.

A storm system is expected to rapidly strengthen off the coast of the mid-Atlantic and produce significant snowfall and gusty winds from the Carolinas to the Northeast.
