March 2014 nor'easter

On March 24, an extratropical disturbance developed in the Gulf of Mexico, just off the coast of South Texas.[6] Within a day, the developing storm crossed over Florida, before emerging off the east coast of the Southeastern United States on March 25.[7] Late on March 25, the winter storm emerged off the coast of the Southeastern United States and began to undergo explosive intensification, becoming a bomb cyclone by March 26,[5] and absorbing another weaker winter storm to the west in the process.[8] However, the storm's path remained off-shore, which resulted in relatively minor impacts to most of the Northeastern United States. Despite the storm's distance from the coast, the system caused wind damage and blizzard-like conditions across New England and eastern Canada. Powered by moisture coming from the Gulf of Mexico, as well as the opposing air masses, the storm quickly became a superstorm with a gale-force wind field four times larger than that of Superstorm Sandy, during the extratropical duration of the latter system, which was extremely unusual for a storm at that time of the year.[5] Later on March 26, the massive nor'easter reached a peak intensity of 954 millibars (28.2 inHg), shortly before it made landfall in Nova Scotia.[4][9] The storm also had peak sustained winds of 89 mph (143 km/h), and maximum gusts up to 119 mph (192 km/h), while unofficial records measured wind gusts up to 129 mph (208 km/h). Early on March 27, the superstorm made landfall on Nova Scotia and weakened to a strong nor'easter.[10] The storm continued to move towards the north, while gradually beginning to weaken. Later on the same day, the nor'easter weakened to a 973 millibars (28.7 inHg) storm and moved northward into the Labrador Sea.[11] On March 28, the storm stalled in the middle of the Labrador Sea.[12] Early on March 29, the nor'easter weakened further to a 1,002 millibars (29.6 inHg) disorganized extratropical storm, even resumed a slow eastward track.[13] Later on the same day, the northern part of the system reached Disko Bay, even as it continued to deteriorate.[14] Early on the next day, the storm's center of circulation collapsed as the system became elongated, due to its interaction with a ridge of high pressure over Greenland, even while the system's center of circulation remained off the east coast of Greenland and stalled, weakening to a 1,010 millibars (30 inHg) low.[15] Several hours later, the storm's remnants were absorbed into a frontal zone.[16][17]

Aside from the impacts in eastern Canada, the Northeastern United States was battered with areas of snow and hurricane-force winds, with winds gusting up to 94 mph (151 km/h) in Chatham, Massachusetts.[18][2] The snow at Dulles Airport helped push them to their snowiest March on record.[19] The highest snowfall totals were recorded at 12.2 inches (31 cm) near Beech Mountain, and 12 inches (30 cm) was measured at Black Mountain, Kentucky.[2]
