Typhoon Joan was the 25th named storm of a season that had what ACE rating?
Typhoon Joan (1997) Typhoon Joan of October 1997 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. 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 active 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.
1971 Atlantic hurricane season The 1971 Atlantic hurricane season was fairly active with several notable storms. Hurricane Edith, the strongest of the season, was a Category 5 on the Saffir-Simpson scale, the highest category on the scale. It struck Nicaragua at peak intensity, killing dozens, and later hit southern Louisiana. Until 2003, Hurricane Ginger held the record for the longest known duration of a North Atlantic tropical cyclone, lasting 27.25 days from early September to early October; it is currently the second longest-lasting Atlantic hurricane. Ginger moved ashore in North Carolina, producing heavy rains and damaging winds. An unnamed storm in August attained hurricane status further north than any other Atlantic hurricane. Between 11 and 12 September five tropical cyclones were active at the same time, the record for the Atlantic basin.
