US Northeast Pounded by 'Bomb Cyclone', Thousands of Houses, Offices Without Power

US Northeast Pounded by 'Bomb Cyclone', Thousands of Houses, Offices Without Power

A massive winter storm has slammed the East Coast from Florida to ME, bringing with it snow, high winds, and frigid temperatures that are creating hard traveling conditions across a wide swath of the Northeast. New York's LaGuardia Airport announced that more than 90% of its flights Thursday would be canceled because of the storm.

Airlines canceled more than 570 flights in the US on Wednesday and a whopping more than 2,500 flights for Thursday, according to flight tracking website FlightAware.

Almost 500 members of the National Guard were activated along the East Coast to assist with emergency response, including 200 in NY state, the U.S. Department of Defense said in a statement. There are also warnings over coastal flooding, downed trees and power lines along the East Coast.

Meteorologists have dubbed the freezing storm a bomb cyclone, because it undergoes "bombogenesis" as it intensifies over a short time period.

A bomb cyclone happens when atmospheric pressure in the middle of the storm drops at least 24 millibars over 24 hours, quickly increasing in intensity.

New York City and Philadelphia will plummet to 3 degrees this weekend.

"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.

Update January 4th, 9:19AM ET: The story has been updated to clarify that winter storms aren't named by the National Weather Service, but can be named by others.

This storm's pressure dropped 53 millibars in 21 hours, Weather Channel meteorologist Jon Erdman said, which ranks it among the most explosive East Coast storms ever seen.

A cyclone warning has been issued for NY where as much as 30cm of snow is expected, as well as some other areas in Long Island, New Jersey and CT. Capital Weather Gang contributor Jordan Tessler posted two nice maps which shows storm tracks from Washington's biggest snowstorms (on the left) vs. the predicted track for Thursday's storm - which is well to the east (on the right). Extra-tropical cyclones have an intense contrast between cold temperatures in the north and warmer temperatures in the south.

Three of those were in North Carolina where trucks skidded off snow-covered roads and overturned, WBALTV reported.

Temperatures are expected to be in the 20s on Thursday as snow moves into the region.

Instead, "bomb cyclone" refers to a phenomenon expected to occur as this weather event unfolds.

The weather pattern has already brought snow to the US South as far down as Florida."The situation has continued to deteriorate", said New York Governor Andrew Cuomo as he declared a state of emergency on Thursday.

The operators of New York's John F. Kennedy International Airport were struggling to recoup from Thursday's storm.

Southern states were also affected, with unseasonal deep freezes in places like Charleston, S.C., and Savannah, Ga.

The fierce cold will reach from New England to the Midwest and down to the Carolinas, forecasters warned, adding that low-temperature records could be broken across the region over the coming days.
