context_page_description: Typhoon Nabi, known in the Philippines as Typhoon Jolina, was a powerful typhoon that struck southwestern Japan in September 2005. The 14th named storm of the 2005 Pacific typhoon season, Nabi formed on August 29 to the east of the Northern Mariana Islands. It moved westward and passed about 55 km north of Saipan on August 31 as an intensifying typhoon. On the next day, the Joint Typhoon Warning Center upgraded the storm to super typhoon status, with winds equivalent to that of a Category 5 hurricane on the Saffir–Simpson Hurricane Scale. The Japan Meteorological Agency estimated peak ten-minute winds of 175 km/h on September 2. Nabi weakened while curving to the north, striking the Japanese island of Kyushu on September 6. After brushing South Korea, the storm turned to the northeast, passing over Hokkaido before becoming extratropical on September 8, before dissipating on September 12.
  The typhoon first affected the Northern Mariana Islands, where it left US$2.5 million in damage, while damaging or destroying 114 homes. The damage was enough to warrant a disaster declaration from the United States government.
context_section_description: On August 28, a large area of convection persisted about 1,035 km (645 mi) east of Guam. Located within an area of moderate wind shear, the system quickly organized while moving westward, its track influenced by a ridge to the north. At 00:00 UTC on August 29, a tropical depression formed from the system, classified by the Joint Typhoon Warning Center (JTWC) as Tropical Depression 14W. In initial forecasts, the agency anticipated steady strengthening, due to warm sea surface temperatures in the area. At 12:00 UTC on August 29, the Japan Meteorological Agency (JMA) upgraded it to a tropical storm. As such, the JMA named the storm Nabi. About 12 hours later, the JMA upgraded Nabi further to a severe tropical storm, after the convection organized into spiral rainbands. At 18:00 UTC, Nabi intensified to typhoon status, reaching ten-minute sustained winds of 120 km/h (75 mph).
  On August 31, Nabi passed about 55 km (35 mi) north-northeast of Saipan in the Northern Mariana Islands during its closest approach. The typhoon continued to intensify quickly as it moved to the west-northwest. On September 1, the JTWC upgraded the storm to a super typhoon and later estimated peak one-minute winds of 260 km/h (160 mph); this is the equivalent of a Category 5 on the Saffir–Simpson scale. By contrast, the JMA estimated peak ten-minute winds of 175 km/h (110 mph) on September 2, with a barometric pressure of 925 mbar (27.3 inHg). While at peak intensity, the typhoon developed a large 95 km (60 mi) wide eye. For about 36 hours, Nabi maintained its peak winds, during which it crossed into the area of responsibility of PAGASA; the Philippine-based agency gave it the local name "Jolina", although the storm remained away from the country.
  On September 3, Nabi began weakening as it turned more to the north, the result of an approaching trough weakening the ridge. Later that day, the winds leveled off at 155 km/h (100 mph), according to the JMA. On September 5, Nabi passed near Kitadaitōjima and Yakushima, part of the Daitō and Ōsumi island groups offshore southern Japan. Around that time, the JTWC estimated that the typhoon reintensified slightly to a secondary peak of 215 km/h (130 mph). After turning due north, Nabi made landfall near Isahaya, Nagasaki around 05:00 UTC on September 6, after passing through the Amakusa of Kumamoto. Shortly thereafter, the storm entered the Sea of Japan. The typhoon turned to the northeast into the mid-latitude flow, influenced by a low over the Kamchatka Peninsula. At 18:00 UTC on September 6, the JTWC discontinued advisories on Nabi, declaring it extratropical, although the JMA continued tracking the storm. On the next day, Nabi moved across northern Hokkaido into the Sea of Okhotsk. The JMA declared the storm as extratropical on September 8, which continued eastward until the JMA ceased monitoring the storm's remnants on September 10, while situated south of the Aleutian Islands. The remnants of Nabi weakened and later moved into southwestern Alaska on September 12, dissipating soon afterward.
