The Northeast is bracing for a 'bombogenesis' that experts say will bring violent 80mph wind, torrential downpour, snow and heavy flooding, resembling the harshness of January's 'bomb cyclone'.
Weather experts said Thursday that Winter Storm Riley will undergo 'bombogenesis', caused by a rapid drop in atmospheric pressure of at least 24 millibars in a period of 24 hours or less.
The drop in atmospheric pressure will force the storm to form into an intense nor'easter into Friday.
A sudden pressure plummet on Friday is expected to hit the Atlantic coast leading into Saturday.
'Please take this storm seriously,' the National Weather Service in Boston said. 'For those living along the coast, this is a LIFE & DEATH situation.'
From Boston down through Rhode Island, two to five inches of snow is expected.
On Thursday night, snow started to spread across the eastern Great Lakes and into upstate New York and northern Pennsylvania.
