Typhoon Pongsona

Typhoon Pongsona (international designation: 0226, JTWC designation: 31W) was the last typhoon of the 2002 Pacific typhoon season, and was the costliest United States disaster in 2002. The name "Pongsona" was contributed by North Korea for the Pacific tropical cyclone list and is the Korean name for the garden balsam. Pongsona developed out of an area of disturbed weather on December 2, and steadily intensified to reach typhoon status on December 5. On December 8 it passed through Guam and the Northern Marianas Islands while near its peak winds of 175 km/h (110 mph ). It ultimately turned to the northeast, weakened, and became extratropical on December 11.

Typhoon Pongsona produced strong wind gusts peaking at 278 km/h (173 mph ), which left the entire island of Guam without power and destroyed about 1,300 houses. With strong building standards and experience from repeated typhoon strikes, there were no fatalities directly related to Pongsona, although there was one indirect death from flying glass. Damage on the island totaled over $700 million (2002 USD, $893 million 2013 USD), making Pongsona among the five costliest typhoons on the island. The typhoon also caused heavy damage on Rota and elsewhere in the Northern Marianas Islands, and as a result of its impact the name was retired.
