Part of the 1997 Pacific typhoon season | |
Typhoon Joan was the longest-lasting super typhoon at the time, maintaining 1-minute maximum sustained winds of at least 240 km/h (150 mph) for 4.5 days.[nb 1] Joan, concurrently with Typhoon Ivan to its west, also became the strongest typhoons at the same time in the northwest Pacific Ocean. The 25th named storm during the hyperactive 1997 Pacific typhoon season, Joan developed from the same trough as Typhoon Ivan on October 11. It moved northwestward and later to the west, undergoing explosive deepening to its peak intensity on October 15. One typhoon warning agency estimated that Joan was among the strongest storms on record in the basin, and that Ivan and Joan marked the first occurrence of simultaneous super typhoons. While near peak intensity, Joan passed between Anatahan and Saipan in the Northern Marianas Islands. Later, the typhoon weakened and turned to the north and east, becoming extratropical on October 24.
On Saipan, Typhoon Joan destroyed 37 houses and caused an island-wide power outage. Three people were injured due to boarding up their house during the storm. On nearby Anatahan, high winds caused $200,000 (1997 USD) worth of crop and property damage. Later, high waves affected southern Japan and northwestern Hawaii. On Chichi-jima, Joan caused a boat to capsize, killing one of its occupants and leaving two others missing.
