Typhoon Chataan (international designation: 0206, JTWC designation: 08W, PAGASA name: Gloria) was the deadliest natural disaster in the history of Chuuk, a state in the Federated States of Micronesia (FSM). The typhoon formed on June 28, 2002, near the FSM, and for several days it meandered while producing heavy rainfall across the region. On Chuuk, the highest 24-hour precipitation total was 506 mm (19.9 in), which was greater than the average monthly total. The rain produced floods up to 1.5 m (4.9 ft) deep, causing landslides across the island that killed 47 people. There was also one death on nearby Pohnpei, and damage in the FSM totaled over $100 million.[nb 1] After affecting the FSM, Chataan began a northwest track as an intensifying typhoon. Its eye passed just north of Guam on July 4, though the eyewall moved across the island and dropped heavy rainfall. Totals were highest in southern Guam, peaking at 536 mm (21.1 in). Flooding and landslides from the storm severely damaged or destroyed 1,994 houses. Damage on the island totaled $60.5 million, and there were 23 injuries. The typhoon also affected Rota in the Northern Marianas Islands with gusty winds and light rainfall. Typhoon Chataan attained its peak intensity of 175 km/h (110 mph) on July 8. It weakened while turning to the north, and after diminishing to a tropical storm Chataan struck eastern Japan on July 10. High rainfall, peaking at 509 mm (20.0 in), flooded 10,270 houses. Damage in Japan totaled about $500 million. The name Chataan means "rainy day" in the Chamorro language, which is spoken on Guam. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) named the storm Gloria while the typhoon was in the vicinity of the country.
