East coast of America braces for a 'bomb cyclone' of freezing weather

East coast of America braces for a 'bomb cyclone' of freezing weather

"There's a strong tendency to focus on the snow amounts, but please keep in mind the bitter cold and very low wind chills which follow this storm", Szatkowski said.

Sunday morning (Monday NZT) should bring the coldest temperatures from Portland, Maine, to Washington DC. "It becomes a question of common sense for New Yorkers".

Weather forecasters had warned that the storm system could shift off its current track.

A massive winter storm is burying the East Coast, with heavy snow falling from New Jersey to ME as road crews in Georgia are cleaning up patches of ice.

Coastal eastern MA, including Martha's Vineyard and Nantucket, could see damaging wind gusts of up to 70 miles per hour Thursday, Dean said.

Bombogenesis is said to occur when a storm's central barometric pressure drops at least 24 millibars in 24 hours.

Americans along the East Coast faced potential power outages in bitterly cold sub-freezing temperatures - so far, some 24,000 customers in Virginia, 9,000 in MA, and thousands more in Georgia, South Carolina and Florida are already affected. Residents of southeast Georgia were treated to a rare half foot of snow (15 centimeters).

Even as much of the United States' East Coast is in the grip of a harsh cold wave, a phenomenon known as "bombogenesis" could make things worse.

The Nor'easter that is now tracking along the East Coast will be a true "bomb" by Thursday afternoon.

What that's actually referring to is when a storm "bombs out" which is when the central pressure of a storm decreases at least 24 millibars in 24 hours.

Wind gusts of up to 88.5 km/h were expected through Friday on Long Island and southeastern CT, with wind chills as low as minus 29 Celsius, increasing the risk of frostbite and hypothermia from prolonged exposure. Locally, the biggest question remains how far west will the snow advance?

Ahead of that threat, snow plows and salt trucks were dispatched along streets and highways, and schools were closed through much of the region.

"Some computer models are projecting a minimum central air pressure of below 950 millibars at its peak, which would be almost unheard of for this part of the world outside of a hurricane", wrote Mashable's Andrew Freedman. Power outage is also a concern, the NWS said. Wicked cold air sourced from Siberia, the North Pole and Greenland will all converge on the region. According to The Washington Post, parts of eastern America will experience temperatures around 20 to 40 degrees below normal before the weather finally begins to thaw early next week.

You see, Grayson just happens to be the name of the dirtiest, most-hated college basketball player in the country: Duke's Grayson Allen.

On Saturday morning, subzero cold is forecast over nearly all of New England, with single digits in the Mid-Atlantic. The high in Burlington, Vermont, on Saturday may only be minus 5 degrees, he said.
