Typhoon Megi (pronounced [me̞.ɟi]), known in the Philippines as Super Typhoon Juan, was one of the most intense tropical cyclones on record. Megi, which means catfish in Korean (Hangul: 메기), was the only super typhoon in 2010. Early on October 18, Megi made its first landfall over Luzon. By passing Luzon, Megi weakened but gradually regained strength in the South China Sea, before weakening and losing its eyewall in the Taiwan Strait. Megi made its second landfall over Zhangpu in Fujian, China on October 23.
Megi killed 31 people and caused $255.1 million (2010 USD) in damage over Luzon, making it one of the costliest typhoons in the Philippines. After moving to the South China Sea, the outflow of Megi and a weather front together brought torrential rainfall, caused $42.2 million (2010 USD) in damage and killed 38 people in Yilan, Taiwan, making Megi the deadliest typhoon of 2010 in Taiwan. Megi also caused $411.7 million (2010 USD) in damage over Fujian, China, although there were no deaths by the storm in the province.
Late on October 10, a tropical disturbance formed east-southeast of Guam. There were favorable environmental conditions, such as low vertical wind shear, good upper-level divergence and poleward outflow. The system began to significantly develop on October 12, prompting the Joint Typhoon Warning Center (JTWC) issuing a Tropical Cyclone Formation Alert at 09:00 UTC. Several hours later, the Japan Meteorological Agency (JMA) began monitoring the system as a tropical depression. Early on October 13, JTWC also classified the system as a tropical depression and designated it 15W.
