Hurricane Madeline was a Category 4 hurricane that made landfall in Mexico in October 1976. Madeline formed on September 29, not far from Central America. The next day, the circulation dissipated, and as a result weakened to a remnant low. Four days later, on October 3, the low regenerated into a tropical depression. The system remained weak for three days as it drifted west-northwest. When it began to recurve towards Mexico on October 6, the cyclone rapidly intensified, eventually making landfall at peak intensity as a Category 4. Shortly after landfall, the cyclone rapidly dissipated. Prior to the arrival of Madeline, 15,000 people evacuated form the coast, which had already been impacted by Hurricane Liza. Heavy damage was reported, along with seven fatalities. Two dams were flooded; extensive crop damage was reported. ==Meteorological history== Early on September 27, 1976, the Eastern Pacific Hurricane Center (EPHC) reported that a tropical disturbance had formed about 770 km (480 mi) to the southwest of San Jose, Costa Rica. During the next two days the disturbance slowly developed while moving northwest. By the morning of September 29, the disturbance was upgraded to a 40 mph (65 km/h) tropical storm and based on ship reports and satellite imagery. Due to the fact that it attained tropical storm status, it was named Madeline. At this time, the cyclone had developed a center of circulation.〔 Its intensification was short-lived and Madeline remained at tropical storm strength for just 12 hours before it was downgraded into a tropical depression.〔 Madeline remained at tropical depression strength until September 30. At that time, the EPHC reported that the circulation center was no longer visible and downgraded the system to a remnant low, while located 575 mi (925 km) to the southeast of Acapulco, Mexico.〔 Over the following days, the low moved towards the west and started to regenerate with a circulation center becoming visible early on October 3. Based on this, the EPHC re-upgraded Madeline to a tropical depression.〔 Continuing to intensify, Madeline was soon upgraded to a tropical storm for the second time. During the next day or two, Madeline remained near stationary before turning towards the northeast on October 5.〔 As the cyclone moved over an area of warm seas surface temperatures, the storm started to intensify. During the next day, Madeline slowly developed an eye before intensifying into a hurricane. In addition, a Hurricane Hunter aircraft reported winds 75 mph (120 km/h) winds and a pressure of 984 millibars.〔 During October 7, with warm water helping to fuel its intensification, Madeline quickly intensified into a Category 2 hurricane, and was upgraded to a major hurricane (Category 3 or higher on the Saffir-Simpson Hurricane Scale) early on October 8. Based on hurricane hunter reports, Madeline reached its peak sustained winds of 145 mph (230 km/h) and a peak pressure of 940 millibars early on the 8th. This made Madeline a moderate Category 4 hurricane. Later that morning Madeline made landfall to the northwest of Zihuatanejo as a powerful Category 4 hurricane, before it rapidly dissipated over land.〔 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 Madeline (1976)」の詳細全文を読む スポンサード リンク
