Typhoon Prapiroon (2000)

Typhoon Prapiroon (Thai: พระพิรุณ) , known in the Philippines as Typhoon Lusing, was the costliest tropical cyclone to strike the Korean Peninsula and the tenth costliest in the West Pacific on record, as of August 2023.

Prapiroon developed as a tropical depression on August 24, 2000, and took a primarily northerly course for much of its duration. However, 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 in 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.
