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