At least seven states have been given blizzard warnings by the National Weather Service as Winter Storm Greyson delivers what many are calling a “Bomb Cyclone” of heavy snow and hurricane-like winds.
The National Weather Service issued blizzard warnings for parts of Delaware, Virginia, Maryland, coastal New Jersey, Long Island, N.Y., and coastal eastern New England. Most of those areas could see at least a foot of snow, while nearly 2 feet of snow was projected in locales further north.
Several locations from northeast North Carolina and the Virginia Tidewater to Delaware and the Jersey shore have already picked up 6 inches of snow, including Wildwood, New Jersey, Stockley, Delaware, and Hampton, Virginia. Newville, Virginia, between Norfolk and Richmond, tallied 8.5 inches of snow.
The National Weather Service warned of “whiteout conditions” in coastal New Jersey and Delaware, with heavy snow and wind gust from 45 to 60 mph.
Snow was falling at the rate of 1 inch per hour at New York’s LaGuardia Airport, and 1 inch of snow was already on the ground at JFK Airport as of 7 a.m. EST. Whiteout conditions were also in place on Long Island, as The Weather Channel meteorologist Mike Seidel experienced.
Wind gusts over 50 mph have been frequent Thursday morning from the Outer Banks of North Carolina to the Delmarva Peninsula. Overnight, some gusts over 70 mph were clocked in eastern North Carolina.
Wind-driven rain was hammering Cape Cod, Martha’s Vineyard and Nantucket Island, with a gusts over 70 mph already measured at Nantucket.
Blizzard warnings remain in effect for much of the coast from Maine to far northeastern North Carolina, including Boston, Portland, Maine, Atlantic City, New Jersey, and Norfolk, Virginia.
Winter storm warnings have been issued to the west of the blizzard warnings, including much of the Interstate 95 Northeast urban corridor from Maine to Delaware. This includes New York City and Philadelphia.
Grayson’s intensifying low will track north-northeast off the Eastern Seaboard Thursday, before plowing into Atlantic Canada Thursday night into Friday.
This explosive development is what meteorologists call bombogenesis, defined by a rapid drop in atmospheric pressure of 24 millibars or more in a period of 24 hours, criterion already well satisfied.
