‘Bomb Cyclone’ Wind Storm Set to Roar Up the East Coast

  • Jan 03, 2018

What to Expect from this ‘Bomb Cyclone’


A powerful winter storm, known as a ‘bomb cyclone’ will make for a messy end to the work week along the entire immediate East Coast. This winter storm will bring snow and ice. Earth Networks Meteorologists James West and Anthony Sagliani expect parts of New England to experience blizzard conditions as well.

Why and When is this Happening?

Frigid, arctic air is already in place throughout the eastern U.S. This is one of the main ingredients needed for a messy, wintry weather mix. Soon, it will mix with a low-pressure system. We expect this system to develop and intensify later this morning and afternoon off the coast of northeastern Florida and southeastern Georgia. The low will provide the moisture needed for this ‘bomb cyclone’s’ snow and ice.

Believe it or now, rain switched over to freezing rain, sleet, and snow this morning across northeastern Florida and southeastern Georgia. Depending on temperatures, up to a quarter of an inch of ice could accumulate through this afternoon across northeastern Florida and southeastern Georgia.

A changeover to snow will occur across interior southeastern Georgia. There, up to 2-4 inches are possible. In places where the snow begins sooner this morning, up to 6 inches of snow will be possible by the time the snow departs up the coast this evening.

The storm and ice will cause roads to become slick and dangerous. Widespread power outages are also possible. Why do winter power outages happen? In this case, the accumulating ice will bring down trees and power lines. This area is not accustomed to the wintry weather and it might take a couple of days for the area to return to normal. Transportation departments and other government bodies responsible for clearing snow should ensure they have equipment ready to go already.

It Gets Worse

The storm will continue to intensify as it crawls up the East Coast, bringing a mixture of up to 2 inches of snow and a glaze of ice to the coast of the Carolina’s tonight and early Thursday. The storm will speed up the coast Thursday afternoon. Then, it will bring up to 6 inches of snow form the Virginia Tidewater, including Virginia Beach and Norfolk, to the southern Delmarva Peninsula tonight into Thursday afternoon. High winds roaring off the coast will also cause reduced visibility, dangerous roads, and some coastal flooding.

There’s a chance that light snow could produce up to a dusting of accumulation as far west as the Mid-Atlantic’s Interstate 95 corridor early Thursday. This includes:

  • Richmond, Va.
  • Washington, D.C.
  • Baltimore, Md.
  • Northern Deleware
  • Philadelphia


Snow will move into eastern Long Island and New England later tonight or early Thursday morning and continue through Thursday. Snowfall accumulations will be in the 9 to 12 inches range across eastern Long Island and southeastern and eastern New England. This includes the greater Boston area. more inland locations will receive 3-6 inches of snow. This includes the greater New York  City area and western New England, with a rapid drop-off in accumulations west of the Hudson River and I-91 in New England.

Besides the snow, New England needs to worry about winds. Wind gusts that could reach 60-60 mph will wallop coastal New England from Cape Cod and the adjacent islands northward into eastern Maine. This will create blizzard conditions. Zero visibility will make travel dangerous and coastal flooding and beach erosion will be possible along the immediate coast.

What is a ‘Bomb Cyclone’ any way?

We bet the last sentence about the beach erosion and coastal flooding reminded you a bit of a hurricane. That’s because that’s what this storm is most like.

‘Bomb Cyclones’ are also known as winter hurricanes. We call it a “bomb” because its pressure is predicted to fall so fast. Remember when we covered Hurricane Maria and Irma in the early fall? They intensified when the pressure dropped.

Same goes for this winter storm. It will strengthen at an explosive pace tonight. This storm could possible rank as the most intense over the waters east of New England in decades at this time of the year. Luckily, the most extreme conditions will remain out on the ocean.
