January 31 – February 3, 2021 nor'easter

From January 31 to February 3, 2021, a powerful, severe, and erratic nor'easter, referred to as the 2021 Groundhog Day nor'easter and unofficially named Winter Storm Orlena by the Weather Channel, impacted much of the Northeastern United States and Eastern Canada from February 1–3 with heavy snowfall, blizzard conditions, strong gusty winds, storm surge, and coastal flooding. The storm first developed as an extratropical cyclone off the West Coast of the United States on January 25, with the storm sending a powerful atmospheric river into West Coast states such as California, where very heavy rainfall, snowfall, and strong wind gusts were recorded, causing several hundred thousand power outages and numerous mudslides.
