early on october 27, a tropical wave developed into a tropical depression. the system strengthened into tropical storm tanya later that day. tanya initially tracked northeastward due to a shortwave trough, though an upper-level cyclone soon turned the storm toward eastward. early on october 29, tanya was upgraded to a hurricane. on the following day, a cold front to the west forced the cyclone to accelerate northeastward. despite slightly cooler water, tanya strengthened a bit more that afternoon, reaching its peak intensity with maximum sustained winds of 85 mph (135 km/h) and a minimum barometric pressure of 972 mbar (28.7 inhg). that intensity was maintained until late on october 31, when the storm weakened as it traveled over cooler waters. early on november 1, tanya began to lose tropical characteristics while heading rapidly northeast towards the azores. the system was downgraded to a tropical storm on november 1. that evening, tanya became extratropical near the central azores. the remnants turned northward and were absorbed by another extratropical cyclone early on november 3.
