Typhoon Nat was a 1991 typhoon known for its unusual track and its long duration. The storm originated east of Luzon and ended in mainland China.
The storm originated north of the Philippines, later moving west and later east, eventually becoming a tropical storm at a speed of 12 kilometres per hour (7.5 mph), after a while, the storm became a category 1, then moved west at an increased speed of 15 kilometres per hour (9.3 mph), then had peak winds as a category 2 typhoon with 155 kilometres per hour (96 mph). The storm later moved south, weakening into a tropical storm; after multiple days, the storm became a tropical depression, then became a tropical storm again, moving north. The storm later became a category 1 typhoon, then dissipated over mainland China.[1][2] The "most unusual" track for Typhoon Nat was reportedly affected by two other typhoons, namely Tropical Storm Luke and Typhoon Mireille.[1]: 44
