A "bomb cyclone" or "climate bomb" is an informal term used to refer an explosive cyclogenesis. This generally happens when the central pressure of a low-pressure system falls via 24 millibars in 24 hours. This would further cause violent winds developing around the system.
The winds would be sturdy enough to cause trees tumbling and can cause structural damages. The upcoming winter is more like a winter hurricane which will be the eastern US’s most severe in decades.
It comes as the average temperature across the continental US hovered around -12.7 on Tuesday morning. On Thursday and Friday, the storm is predicted to increase alongside the eastern seaboard of the USA, bringing strong winds, rain, sleet, and snow.
The storm is forecast to go through speedy cyclogenesis over the Atlantic Ocean, and as per the predictions, areas north of New York carries the highest threat impacts from heavy snow and strong winds.
Predominant north-eastern cities such as Boston are vulnerable to blizzards and is expected to cause disruption in air and road traffic alongside power outages are also possible.
