By 20:00 UTC, most of the snow had come to an end in New Jersey, Delaware, and Washington D.C., as the low began to move inland over New England subsequently it also began to weaken as it traveled further inland, and by early on March 15, snow began to end in more parts of the region. The low subsequently reached its peak intensity of 974 millibars (28.8 inHg) while just inland over Long Island. The storm continued to intensify as it drifted northeastwards towards Long Island, continuing to produce an expansive area of snow with heavier rates embedded in snowbands across Connecticut, northern New York and most of interior New England, as well as parts of Canada. The storm began to rapidly deepen as it moved parallel to the East Coast of the United States, with the central pressure dropping to 986 millibars (29.1 inHg) by 15:00 UTC on March 14 while it was just off the Maryland coastline. īy 21:00 UTC that night, a new surface low developed off the Georgia coastline with a central pressure of 1,010 millibars (30 inHg), eventually becoming the dominant low of the nor'easter. Throughout the day, a weak secondary area of low pressure formed in the Gulf of Mexico and drifted northeastwards, while not expected to fuse with the other low to its north, it helped inject moisture from the ocean over the state of Florida, which gradually began to merge with the outermost fringes of the northerly system that had now moved into the Ohio Valley. On March 13 at 15:00 UTC, the Weather Prediction Center began issuing storm summaries while the system was located west-northwest of St. The system moved swiftly across the Upper Midwest throughout the day of March 12, dropping a swath of accumulating snow of 3–6 inches (7.6–15.2 cm) as frontogenesis took place. It eventually moved ashore later that day and transferred its energy to a new surface low, which began to move southeastwards into the United States as an Alberta clipper. On March 11, it began to affect parts of the Northwestern United States as well as British Columbia in Canada. On March 9, an extratropical cyclone formed in the North Pacific Ocean.

It dropped a swath of moderate snow accumulation as it moved across the northern tier of the country, with as much as 13 inches (33 cm) reported. The system also disrupted travel across the country, with numerous flight cancellations at most of the major airports in the Northeast. Several officials had crews with salt trucks ready to deploy to clear roads. Īhead of the storm, residents prepared in advance for the major nor'easter, with blizzard warnings issued for several states, including New York, Pennsylvania, New Jersey, Connecticut, Rhode Island, and Massachusetts. The storm was given various unofficial names, such as Winter Storm Stella, Blizzard Eugene, and Blizzard of 2017. It later coalesced into a powerful nor'easter off the East Coast, producing a swath of heavy snowfall across a large portion of the Northeast. Forming out of an extratropical cyclone near the Northwest, the storm system dived into the northern portions of the United States, dropping light to moderate snow across the Great Lakes, Upper Midwest on March 11–12 before reaching the Ohio Valley the next day. The March 2017 North American blizzard was a major late-season blizzard that affected the Northeastern United States, New England and Canada, dumping up to 3 feet (36 in 91 cm) of snow in the hardest hit areas, mainly New York, Vermont, New Hampshire and Southern Quebec.
