Bomb cyclone

The storm will intensify into a powerful "bomb cyclone" as it blast the East Coast with heavy snow and high winds this weekend, according to FOX Weather.

What is a bomb cyclone?

Meteorologists use the term bomb cyclone to describe a low-pressure system that undergoes "bombogenesis" – defined as a rapid pressure drop of at least 24 millibars in 24 hours or less – indicative of a very intense storm system. In general, the lower the pressure, the higher the strength of the winds.

Saturday weather

By Saturday morning, there will be heavy rainfall in New York City, the Jersey Shore, and Long Island.

As cold air rushes in it will push the system into the city for a rapid change over to rain.  Snow accumulation will be about half an inch by the afternoon. Strong winds are expected, too.
