Tropical Storm Wanda is an active tropical storm that was also a powerful and damaging bomb cyclone[1] that affected much of the Eastern United States. The storm caused flooding in areas previously affected by Hurricanes Henri and Ida.[2][3] The 21st tropical cyclone and named storm of the 2021 Atlantic hurricane season, Wanda originated from non-tropical disturbance over the Southern United States on October 23. The system subsequently moved out into the Atlantic and developed into a powerful 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. The system then weakened and moved eastward, further out into the Atlantic. On October 30, the system transitioned into a subtropical storm and was given the name Wanda. As the system slowly curved southeastward, it continued organizing, and transitioned into a fully tropical storm on November 1.

Damage from the storm is estimated to have exceeded $200 million (2021 USD).[4]

On October 23, a non-tropical disturbance developed over southern Texas.[5] For the next couple of days, the system gradually strengthened while moving eastward, along the US Gulf Coast. On October 25, the system emerged into the Atlantic, off the coast of Georgia, and developed an area of low pressure.[6] On the previous day, the National Hurricane Center (NHC) began monitoring the system, noting that it could potentially develop into a subtropical or tropical cyclone several days later, after it reached the North Atlantic.[7] Early on October 26, the NHC noted that the system had a low chance of developing into a subtropical cyclone before it would merge with another approaching extratropical system, though the storm had a larger chance of becoming subtropical later in the week, after it moved out further into the Atlantic.[8] Afterward, the system began moving northeastward, along the East Coast of the US, developing into an extratropical system while quickly strengthening.[9] On October 26, the system underwent explosive intensification, developing into a nor'easter and a powerful bomb cyclone, with the system's central pressure dropping 28 millibars (0.83 inHg) over the next 24 hours, from 1,008 millibars (29.8 inHg) to 980 millibars (29 inHg) by October 27.[10][3] During this period of time, the nor'easter absorbed another extratropical system over the Northeastern United States, to the west.[11][12] The nor'easter then proceeded to make a counterclockwise loop, while intensifying further, before reaching its extratropical peak intensity of 974 millibars (28.8 inHg) at 09:00 UTC on October 27, off the coast of Massachusetts.[13] Afterward, the system gradually weakened while moving eastward, further out to sea.[14] The NHC continued to monitor the system, though they downgraded its chances of development within the next five days from 40% to 30% by then.[15][16] On October 29, the system began acquiring subtropical characteristics as it grew organized,[17] with the NHC increasing its chances of development over the next two days from 50% to 90% that same day.[18][19] At 03:00 UTC on October 31, Wanda completely shed its frontal structure and transitioned into a subtropical storm, and the NHC initiated advisories on Subtropical Storm Wanda.[20][21] Wanda continued to organize while curving southwestward and then southeastward, and at 21:00 UTC on November 1, Wanda transitioned into a fully-tropical storm.[22]

Current storm information

As of 9:00 a.m. GMT (09:00 UTC) November 2, Tropical Storm Wanda is located within 30 nautical miles of 35°00′N 40°36′W / 35.0°N 40.6°W / 35.0; -40.6 (Wanda), about 800 miles (1,285 km) west of The Azores. Maximum sustained winds are 45 knots (50 mph; 85 km/h), with gusts up to 55 knots (65 mph; 100 km/h). The minimum barometric pressure is 992 mbar (29.29 inHg), and the system is moving east-northeast at 7 knots (8 mph; 13 km/h). Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center of Wanda.

Preparations

More than 100 schools closed in Cape Cod.[1]

Impact

The storm brought high winds, cutting power to more than 600,000 people in New England. A peak wind gust of 94 mph (151 km/h) was reported in Martha's Vineyard, Massachusetts. Scituate reported a gust of 87 mph (140 km/h) and Nantucket experienced gusts of 70 mph (110 km/h). A plane was damaged at the New Bedford Regional Airport after being blown off the runway. In Hingham, a large tree brought down wires.[1] According to Aon Benfield, damage was estimated at over $200 million.[4]
