 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 .
