'Bomb cyclone' brings travel chaos and deaths to USA north

'Bomb cyclone' brings travel chaos and deaths to USA north

It's basically like enduring a weak hurricane - except getting blasted by snow instead of rain.

It has prompted thousands of cancelled flights, shut schools and businesses and sparked fears of coastal flooding and power outages. "It's snow plus the wind which is going to cause the trouble today".

Forecasters predict more than a foot of snow in Boston; up to 8 inches in New York City; and up to 6 inches in Philadelphia. At New York's three major airports - including JFK - and Boston's Logan International, as many as three out of four flights were called off, according to tracking service FlightAware.com.

Officials closed the runways at La Guardia and Kennedy Airports in NY and canceled almost three-quarters of the day's schedule at Newark Liberty International in New Jersey. And American Airlines has suspended all departures from Boston.

At least seven people died in weather-related accidents. Officials have instructed for people to try and stay off the roadway, but that can be hard for people needing to work.

"We're expecting wind gusts between 40 and 50 miles an hour today", Correia said.

The rare type of storm struck the U.S. south-east on Wednesday, also dumping snow in parts of SC and eastern Georgia, said the meteorologist Patrick Burke of the federal Weather Prediction Center.

Major northeastern cities such as Boston risk being hit by blizzards and states of emergency have been issued for Florida, Georgia, North Carolina and Virginia.

Weather forecasters had warned that the storm system could shift off its current track. The snow, combined with "exceptionally strong winds", means crews will be working in near-whiteout conditions, New York City Sanitation Commissioner Kathryn Garcia said.

The cold blast moving behind the storm from the Midwest to the Southeast and Northeast will deliver temperatures plunging as low as single digits during the day and below zero at night.

SEKO Logistics said that the winter storm was, "disrupting global supply chains, with roads, airports and now [sea] ports being closed across the region".

Ellabell, Georgia reported 15cm of snow; Summerville in SC was coated in 18cm; and Pinehurst, North Caroline received 15cm. The airport at Savannah got 1.2 inches - the most the city had experienced in 28 years.

The snow in Tallahassee was the first snow seen in Florida's capital for three decades. SC saw its third heaviest snowfall in one day on record in Charleston, where 5.3 inches of snow was measured Wednesday.

Utility companies across the East worked to fix downed power lines as about 31,000 customers remained without electricity early on Friday, down from nearly 80,000 the day before.

The storm is fueled by intense cold across the USA, which collided with relatively warm air over the Atlantic.

What turns a normal winter storm into a bomb cyclone has to do with pressure.

In simple words, It's the process in which a storm rapidly intensifies through a drop in pressure of at least 24 Millibars within 24 hours.
