 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 <unk> 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 <unk> 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 . Operationally , it was not declared a tropical cyclone until that point , when it was immediately declared Tropical Storm Tanya .
