By 06:00 UTC on January 7, a new low developed just offshore the South Carolina coastline, and this low eventually became the dormant low as the system tracked offshore. The aforementioned low then quickly moved onshore and continued to produce more wintry precipitation, as it tracked eastwards throughout the day on January 6. Īt the same time, a stationary front formed within the northeastern part of the Gulf of Mexico, and once this energy reached the front with cold air in place, snow, sleet, and ice began to break out in areas such as Louisiana, Mississippi, Arkansas, and Alabama as a new area of low pressure formed along the stationary front late on January 5. However, leftover energy from the dissipating system continued to move south towards the Southeast. As it dived southeastwards, the low dissipated because of interaction with the mountains of areas such as Arizona, New Mexico, and Nevada. With cold air in place, heavy snow began to fall in parts of Montana, Oregon, and in the Sierra Mountains, with maximum accumulations of nearly 4 feet. On January 4 around 00:00 UTC, an area of low pressure associated with an atmospheric river moved onshore on the West Coast of the United States. The storm caused nearly 35,000 or more power outages in the south, with at least five fatalities confirmed. Multiple advisories were issued in advance for winter weather in the affected areas. įearful of another disaster reminiscent of that from late January 2014, residents of states such as Louisiana, Mississippi, Alabama, and Georgia prepared in advance for the storm. It produced a swath of moderate snowfall accumulations up the East Coast, with easternmost areas such as parts of Massachusetts receiving up to 1.5 feet (18 in) of snow. It then began to affect the Northeastern United States as it tracked northwards early on January 7. Afterwards, it began to morph into a nor'easter as it moved off the Southeast coast late on January 6, while producing blizzard conditions in the Carolinas. After impacting the Northwest and Southwest, the winter storm went on to strike the Southeast on January 5–6 with snow and ice, with snowfall accumulations up to 4 inches (10 cm).
Moving ashore on the West Coast on January 3, the system produced heavy snowfall in the Sierra Mountains, with nearly 4 feet of snowfall falling in the highest elevations. The January 4–8, 2017 North American winter storm was a major snow and ice storm that affected the Lower 48 of the United States with winter weather. Part of the 2016–17 North American winter
