The October 2021 nor'easter, which eventually became Tropical Storm Wanda, was an erratic nor'easter and tropical cyclone that struck the East Coast of the United States, and meandered across the northern Atlantic Ocean in early November 2021. The powerful extratropical cyclone affected much of the East Coast, causing significant flooding in areas which were previously affected by hurricanes Henri and Ida.[5][6] As Wanda, the cyclone was the twenty-first and final tropical cyclone of the 2021 Atlantic hurricane season. The system originated from a non-tropical mid-level trough that moved across the Southern United States on October 24–25, and moved out into the Atlantic, where a well defined area of low pressure formed. This quickly became a bomb cyclone off the East Coast of the United States on October 27, causing flooding and bringing powerful gale-force winds to the region in the process. Then, on October 30, after weakening and moving eastward out into the Atlantic, the system acquired subtropical characteristics and was given the name Wanda. By 12:00 UTC on November 1, the system transitioned into a tropical storm. Over the next several days, Wanda meandering well west of the Azores, before curving southward and then accelerating northeastward, before degenerating into a post-tropical cyclone on November 7, several hours before merging with a frontal system.
The nor'easter caused over $200 million (2021 USD) in damage in the Northeastern United States, and two storm-related deaths were reported. More than 600,000 customers across the region were without electrical power at the height of the storm. There were no reports of deaths from Wanda.
