“Bomb cyclone” is a mid-latitude storm whose central air pressure falls at a rate of one millibar per hour for 24 hours. The lower the pressure, the stronger the storm. System this week is forecast to become bomb cyclone-like in rapid succession. Bomb cyclones produce heavy rain or snow, coastal flooding and hurricane-force wind gusts. The term was coined in a 1980 research paper by MIT meteorologists Frederick Sanders and John R. Gyakum. Bomb cyclones are often occurring in the fall or winter.
