Typhoon Tip

Typhoon Tip, known in the Philippines as Typhoon Warling, was the largest and most intense tropical cyclone ever recorded. The nineteenth storm and twelfth typhoon of the 1979 Pacific typhoon season, Tip developed out of a disturbance from the monsoon trough on October 4 near Pohnpei. Initially, a tropical storm to the northwest hindered the development and motion of Tip, though after it tracked farther north Tip was able to intensify. After passing Guam, Tip rapidly intensified and reached peak winds of 305 km/h (190 mph) and a worldwide record-low sea-level pressure of 870 mbar (870.0 hPa; 25.69 inHg) on October 12. At its peak strength, it was also the largest tropical cyclone on record with a wind diameter of 2,220 km (1,380 mi). Tip slowly weakened as it continued west-northwestward and later turned to the northeast in response to an approaching trough. The typhoon made landfall in southern Japan on October 19, and became an extratropical cyclone shortly thereafter.
