Storm system brings snow, ice to Florida

Low pressure will take shape east of Florida during the day Wednesday and then rapidly strengthen as it lifts north to a position off the New England coast on Thursday and into the Canadian maritimes Thursday night.

The bomb cyclone is described as being similar to a winter hurricane, with accompanying freezing rain, ice, snow, and powerful winds.

This week's storm is expected to strike New England as a classic bomb cyclone with a dramatic 50-millibar dip in a 24-hour period.

For a storm to be classified a "bomb", it must meet a set of strict criteria, led by a rapid decline in surface-air pressure, which is the weight of the atmosphere.

Even year-round golf paradise Myrtle Beach in northeastern SC wasn't spared, with the overnight temperature dropping to -7 C on Tuesday just before the start of a rare winter storm that was expected to dump up to eight centimetres of snow on the region.

The technical term is bombogenesis but it's often called a "bomb cyclone".

Storm Eleanor set to batter West Sussex
A yellow weather warning has been issued across the South-east ahead of the arrival of Storm Eleanor tonight (Tuesday). The weather alert has been issued by Met Eireann with high winds expected across most counties including Kilkenny.

How much the storm affects the coast is contingent on a number of factors, most notably how far out to sea it tracks.

"Travel will be risky and almost impossible, including during the morning commute on Wednesday", the service said in an advisory for northeastern Florida.

According to the Weather Channel, the NWS in Tallahasse had to issue a winter storm warning for the first time in four years. The difference between the two air masses helps to strengthen the storm system. Snow, sleet and freezing rain may increase in eastern North Carolina and southeast Virginia by Wednesday afternoon.

The storm is also giving forecasters a chance to play with other data-generating instruments, including the new GOES-16 satellite that just settled into position over the Eastern U.S.

By early Thursday morning, snow will cover Long Island and southern New England and will be heavy at times with winds gusting to 50 miles per hour.

This usually happens when a storm system moves over the warm waters of the western Atlantic and the Gulf Stream at the same time arctic cold air moves in behind from the west.
