Forecasters say Winter Storm Iola could undergo ‘bombogenesis’ — a rapid pressure drop tied to high winds, rain and snowfall AP This NOAA satellite image taken Friday afternoon captures a weather system making its way along the eastern seaboard towards coastal New England while expected to intensify into a Nor’Easter. As if news of a barreling nor’easter isn’t enough of a bitter blast, meteorologists are dropping a new bomb as part of this weekend’s forecast. It’s called Bombogenesis. This ominously named meteorological phenomenon is the rapid pressure drop Winter Storm Iola is expected to undergo once hitting the East Coast late Friday night, Weather reported. To be exact, it’s described as a central pressure drop of at least 24 millibars in 24 hours which often creates increased wind speeds, precipitation, heavy snowfall and potential blizzard conditions. Senior meteorologist Stu Ostro explains that its name may make it sound extremely unusual but its process happens fairly often — and just as its name sounds, it is quite like a bomb.

One of the most recent occurences of bombogenesis was in 2013 during the nor’easter dubbed Winter Storm Nemo. That February storm — which at its heaviest dropped 40-inches of snow in parts of Connecticut and led to coastal flooding due to large storm surges — saw its central pressure drop 29 millibars within a span of 24 hours. AP As Iola runs up the northeast, it’s expected to dump a wide streak of snow from southwest North Carolina up into the Canadian border. As Iola runs up the northeast, it’s expected to dump a wide streak of snow from southwest North Carolina up into the Canadian border. New York City is expected to see 3 to 6 inches of snow while Southern and eastern New England are expected to see the largest amounts, exceeding half a foot. The peak time for the snow fall is being eyed as from Friday night through Saturday night. ngolgowski@nydailynews Related Stories City suspends alternate side parking rules for Saturday Nor’easter set to pound New York City with snow and sleet VIDEO: 3 feet of snow falls in 40 seconds Source: nydailynews/ newsnyork/forecasters-say-winter-storm-iola-could-undergo-bombogenesis-a-rapid-pressure-drop-tied-to-high-winds-rain-and-snowfall/
