Hurricane Winifred was the last tropical cyclone to make landfall in the busy 1992 Pacific hurricane season. Impacting western Mexico, especially Colima and Michoacán, Hurricane Winifred brought heavy rain and destruction to the area. Rains flooded farms and roads, and caused more than $5 million (1992 USD, $ USD) in damage and a total of three people were killed. The last major hurricane of its season, Winifred existed in October 1992. It formed southeast of Acapulco on October 6 as the twenty-fourth east Pacific tropical cyclone of its season, and recurved as it strengthened. It peaked as a Category 3 hurricane on the Saffir-Simpson Hurricane Scale. It made landfall southeast of Manzanillo, Colima and dissipated inland. ==Meteorological history== On October 1, a disorganized area of thunderstorms existed south of Panama. It gradually headed west-northwestward, slowly organized, and developed deep and concentrated convection. The disturbed area had become organized enough to be considered a tropical depression. Numbered Twenty-Four-E, the cyclone was located about 460 mi (740 km) south-southeast of Acapulco. It moved towards the west-northwest at a speed of about 12 mph (19 km/h), and by the time it was located about south of Zihuatanejo, it had intensified into Tropical Storm Winifred. Winifred steadily became more organized, and late on October 7, the National Hurricane Center (NHC) was anticipating Winifred to reach hurricane intensity within the next 36 hours. A large cyclone, Winifred continued to intensify. Its forward speed decreased as it started to turn to the northwest. By October 8, Winifred become a hurricane while located approximately south-southeast of Manzanillo.〔 A small eye became evident on satellite imagery, and thus the winds increased to 85 mph (145 km/h). Winifred then intensified into a moderate Category 2 hurricane on October 9. Although the eye briefly disappeared, slight intensification was anticipated. The hurricane was curved north by an upper-level trough. Winifred peaked in intensity as a major hurricane (Category 3 or higher on the Saffir-Simpson Scale). At this time, Winifred, had central pressure of and winds of 115 mph (185 km/h).〔 This made Winifred the final hurricane– major or otherwise– of the 1992 Pacific hurricane season. However, it was operationally believed to have peaked as a Category 2 hurricane; the NHC did not issue any advisories with winds any higher than 110 mph (175 km/h).〔 Hurricane Winifred re-curved to the north-northeast, increased in forward speed, and slightly weakened as it approached land. On October 9, it made landfall about east-southeast of Manzanillo. At the time it was a weak Category 2 hurricane with winds of 110 mph (175 km/h) and a central pressure of . Hurricane Winifred quickly weakened after landfall, and weakened to a tropical storm less than three hours later, which was early on October 10. Later on October 10, Winifred weakened to a tropical depression, before dissipating over the mountains of central Mexico.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hurricane Winifred (1992)」の詳細全文を読む スポンサード リンク
