[1]  [DOC] Typhoon Oliwa was one of a record eleven super typhoons in the 1997 Pacific typhoon season. It formed in the central Pacific Ocean on September 2 to the southwest of Hawaii, but it became a typhoon in the western Pacific. Oliwa explosively deepened on September 8, increasing its winds from 85 mph to 160 mph in a 24‑hour period. Afterward, it slowly weakened, and after passing east of Okinawa, Oliwa turned northeast and struck Japan with winds of 85 mph (140 km/h). There, it affected 30,000 people and killed 13; thousands of houses were flooded, and some were destroyed. Offshore South Korea, the winds and waves wrecked 28 boats, while one boat went missing with a crew of 10 people. Typhoon Oliwa dissipated on September 19 in northern Pacific Ocean near the International Date Line. [END]
