in northeaster storm in de VS

Het noordoostelijke deel van de VS is afgelopen dagen getroffen door een northeaster. De boekhouding moet nog opgemaakt worden maar het kon wel eens een van de grotere jongens zijn uit de recente geschiedenis van dergelijke fenomenen. Hieronder wat informatie afkomstig van weatherunderground



By the time Friday is here, people along the length of North America’s East Coast will be recuperating from a punishing round of heavy snow, high winds, and bitter cold. This nor’easter—dubbed Grayson by The Weather Channel—will rank among the most impressive of recent decades in its fast development, deep low pressure, and fierce winds. Various models agreed that Grayson’s surface low would deepen by an astounding 30-40 millibars or more from late Wednesday to late Thursday, more than qualifying the midlatitude cyclone as a meteorological “bomb” (defined as 24 millibars of deepening in 24 hours). The deepening rate could be among the strongest observed off the East Coast in the last several decades of records, according to David Roth (NWS). Update: Preliminary analyses from NOAA/NWS Weather Prediction Center as of midday Thursday show that Grayson deepened by an incredible 59 millibars in just 24 hours, which would be a record for midlatitude storms in this part of the Northwest Atlantic. The central pressure at 10 AM EST was analyzed by WPC at 951 mb.
As of late Wednesday, blizzard warnings covered parts of each coastline from North Carolina to Maine. Some uncertainty in the storm track remained on Wednesday night—complicated by the storm’s rapid development and unusual strength—but Grayson’s center should remain just far enough offshore to keep the worst impacts east of the I-95 corridor until the storm reaches southeast New England. There, Grayson may produce a strong enough blizzard to impress even the hardest-bitten Yankee. Snow amounts won’t be off the charts, but the impact will be worsened by winds at gale force or stronger and frigid temperatures, especially in the 24 to 48 hours after Grayson has passed. Update (12:45 pm EST): Winds had already gusted to 75 mph at Wellfleet, MA, as of midday Thursday. Hurricane Force Wind Warnings were in effect for Outer Cape Cod and Nantucket Island.

Zeer hoge waterstanden langs de noordoostkust van de USA voor de storm (950hPa van zuidwest naar noordoost langs de kust bewegend) uit. In Boston de hoogste waterstanden sinds 1921. Sneeuwstorm en overstroming van de stad rond het havengebied gecombineerd.
