Typhoon Prapiroon, known in the Philippines as Typhoon Lusing, was the costliest tropical cyclone to strike the Korean Peninsula and the fourth costliest in the West Pacific on record.
Prapiroon developed as a tropical depression on August 24, 2000, and took a primarily northerly course for much of its duration, though steering currents caused it to track westward for extended periods of time on two occasions. Intensification was gradual, and on August 26 the system reached tropical storm status, though the system's organization remained rather loose for much of its early developmental history. On August 29, Prapiroon swung near Taiwan and East China as it tracked about the western periphery of a nearby high-pressure area. A day later, the storm reached typhoon intensity within the East China Sea, later attaining peak intensity as a typhoon of moderate strength within the Yellow Sea. On August 31, a slightly weakened Prapiroon made landfall on North Korea and quickly tracked across the Korean Peninsula, before transitioning into an extratropical cyclone in the Sea of Japan on September 1; the system dissipated east of Hokkaido three days later.
Prapiroon originated from a disturbance that developed within the warm tropics southeast of Guam on August 22. Positioned in an area with low wind shear, atmospheric conditions around the system were supportive of tropical cyclone development. After some organization, the Japan Meteorological Agency (JMA) declared the area of disturbed weather to have assumed the characteristics of a tropical depression at 1800 UTC on August 24. Initially tracking westward, the diffuse depression reached a temporary halt and later began to accelerate towards the north on August 25. Strengthening continued at a steady pace thereafter, and at 1800 UTC the following day, the JMA upgraded the depression to tropical storm status, based on corresponding ship reports and satellite intensity estimates, and named the system Prapiroon accordingly. Despite its classification, Prapiroon was loosely defined, as it lacked a primary circulation center and instead was centered around multiple vorticies.
