A massive winter storm known as a “bomb cyclone” will smash into the US East Coast this week. This powerful weather event will bring an even deeper freeze to a region that has suffered bitter cold weather for the past 10 days. The storm in question, which will impact coastal areas from Georgia to Maine, is given its extreme name because of the predicted rapid pressure drop, an indication of the storm’s strength. The bomb cyclone is described as being similar to a winter hurricane, with accompanying freezing rain, ice, snow, and powerful winds. Although the effects of the storm will be acutely felt by East Coast residents, the most extreme weather conditions are expected to remain offshore.
The storm is expected to particularly impact New England, off the coast of which it is expected to be the strongest the region has seen in decades. Boston is expected to receive up to seven inches of snow, in addition to powerful winds capable of knocking down trees and power lines. The temperatures in Boston are expected to drop to 27 degrees below the average for this time of year. When the storm has ended, the entire coast is expected to be hit with another wave of frigid air.
Further south, the storm’s impact will still be substantial. Coastal Georgia and even areas of North Florida are expected to receive some snow, as are coastal cities further north in the Southeast. In Charleston, South Carolina, one to three inches of snow and sleet are expected. By the time the storm reaches New England, its central pressure will have dropped 53 millibars in only 24 hours, an astonishing pressure drop unheard of outside of a hurricane-strength storm. After the weekend, the East Coast is expected to enjoy a respite from winter’s deep freeze when temperatures warm up.
