Lowest pressure 972 mbar (hPa); 28.7 inHg
Fatalities 1 direct
Areas affected Azores
Part of the 1995 Atlantic hurricane season

Hurricane Tanya was the final storm of the very active 1995 Atlantic hurricane season. The twenty-first tropical cyclone, nineteenth named storm, and eleventh hurricane of the season, Tanya developed from a tropical wave while well north of the Lesser Antilles on October 26. The system headed northeastward and strengthened into Tropical Storm Tanya on October 27. Tanya meandered around the central Atlantic, and further intensified into a hurricane on October 29. Thereafter, Tanya tracked northeastward before curving to the east-northeast. After switching to an eastward direction, Tanya weakened to a tropical storm on November 1. Later that day, Tanya passed through the Azores as it was transitioning into an extratropical cyclone.

Throughout the Azores, the extratropical remnants of Tanya produced high winds. As a result, extensive property damage occurred, which included destroyed or damaged houses, and sunken boats; there were also reports of significant damage to agriculture. However, an exact damage toll figure in unknown. In addition, there was one fatality and several injuries.

Meteorological history

The origins of Hurricane Tanya were from a tropical wave that moved off the western coast of Africa in the middle of October. The wave closely followed the path of Tropical Storm Sebastien and was unable to develop in the tropical Atlantic as it moved westward. The system did not begin to become organized until October 25 while south-southeast of Bermuda. However, the Dvorak technique was still unable to classify the system until October 26 as the low-cloud swirl became better organized while moving northward in the central Atlantic. That evening, a closed circulation had formed, and it was classified as Tropical Depression Twenty-One by the National Hurricane Center. On the morning of October 27, it strengthened into a tropical storm, becoming the 19th as well as the final named storm of the season.[1] Operationally, it was not declared a tropical cyclone until that point, when it was immediately declared Tropical Storm Tanya.[2]

Immediately after becoming a tropical storm, the movement of Tanya became hindered by a nearby upper-level low, and it quickly turned eastward before virtually stalling early on October 28.[3] The upper-level low also influenced Tanya in giving it some subtropical characteristics, including a comma-shaped cloud band and maximum winds far from the center of the storm at the time.[1] Despite that, the storm gradually strengthened as it remained over warm waters of about 81 °F (27 °C).[3] That afternoon, it gained full tropical characteristics, as an eye featured was beginning to form in the central dense overcast.[4] The eye became clearly defined, although it was small in size. Early on October 29, Tropical Storm Tanya was upgraded to a hurricane, the eleventh of the 1995 season, as it turned northward in response to the nearby low.[5]

Later on October 29, while slowly tracking north, Tanya leveled off as a low-end Category 1 hurricane. By the next morning, a cold front to the west forced Tanya to accelerate in a more easterly track .[6] It remained fairly well organized with a distinct eye as it became wedged in a narrow zone of warm air between the cold front to the west and the upper-level low to the northeast.[1] Despite slightly cooler water, Tanya strengthened a bit more that afternoon, reaching its peak intensity of 85 mph (135 km/h) with a barometric pressure of 972 mbar (28.7 inHg) as the forward speed increased.[7] That intensity was maintained until late on October 31, when Tanya began to weaken as it traveled over cooler waters and the eye became obscured.[8] Early on November 1, Tanya began to lose tropical characteristics while still a hurricane. Hurricane Tanya was also heading rapidly northeast towards the Azores at the time.[9] Tanya was downgraded from a hurricane to a tropical storm on November 1. Despite weakening, the wind field of Tanya became larger.[10] That evening, Tanya was declared fully extratropical as it passed the Azores.[11] The remnant cyclone turned north, before being absorbed by another extratropical cyclone early on November 3.[1]

Impact, naming and records

Hurricane Tanya was not considered a threat to land, as it did not move through the Azores while a tropical cyclone.[12] The Azores were hit very hard by the storm, which had just been declared extratropical when it hit the region.[1] Damage was particularly severe on the islands of Faial, Pico, Terceira and São Jorge. Extensive property damage was reported, including many sunk boats, many houses were damaged and some destroyed and significant agricultural damage. Many trees and power lines were also knocked down, cutting electricity and hampering communications in the area. The highest wind gusts reported in the Azores were around 105 mph (170 km/h). After the storm, a resolution was submitted to the European Parliament by the Government of Portugal and a disaster area was declared in the islands.[13] One Spanish fisherman drowned and several people were injured.[13]

There were many reports of tropical storm-force winds from ships in the north Atlantic. One ship, with the call sign GBSA, encountered Tanya's winds twice and reported the strongest winds from any ship, 71 mph (112 km/h).[1]

Hurricane Tanya was the first storm to be designated with a name starting with "T" since naming of Atlantic tropical cyclones began in 1950.[14]
