Maximum deepening rate over 24-hours is forecast to be 45 millibars -- which puts the storm in the upper echelon of "bomb cyclones" -- simply a more extreme variety of "cold season" storm that usually harmless mix fish, generate huge waves, and do their job of moving Earth's heat pic.twitter.com/MmNXljhXTa

Getting a lot of questions on what a "bomb cyclone" is. This derives from the work of Fred Sanders (@MIT ) and John Gyakum (@mcgillu) from their 1980 paper, 'Synoptic–dynamic climatology of the "bomb"'. pic.twitter.com/0K1jJBxkdL

From my dissertation on "Warm Seclusion Extratropical Cyclones" -- which are often "bombs"

Northern Hemisphere sees roughly 40-50 of these bomb cyclones each year mainly in months of Sep to March when upper-level jet stream is sufficiently strong + large temperature contrasts pic.twitter.com/sDAsNbEnOu
