AccuWeather says the potential is growing for a very strong nor'easter on Saturday and Sunday with widespread impacts from snow, wind and coastal flooding.

A bomb cyclone is a name that was given to the atmospheric process of 'explosive cyclogenesis' and is used to describe a quickly and deeply strengthening storm. It has also been referred to as 'bombogenesis.'

An arctic blast and a bomb cyclone could hit the Eastern U.S. simultaneously this weekend, causing another winter storm.

Winter's harsh hold on the eastern U.S. shows no sign of easing up, with "dangerously cold temperatures" expected to persist.
