increased, causing vertical wind shear which led to Mac weakening into a tropical depression before dissipating on May 29. Typhoon Nancy (Deling) A broad area of convection formed to the southeast of Pohnpei in mid June. The convection formed a tropical depression on June 21 to the east of the Philippines. Tropical Storm Nancy was named the next and quickly strengthened into a typhoon with max winds of before striking northeastern Taiwan. After departing the island Nancy weakened to tropical storm strength while moving north through the East China Sea. Nancy passed through the Korea Straits just before turning extratropical and accelerating northeastward into the Sea of Japan. Torrential rains fell throughout South Korea, as a result of flooding 12 people were killed and of farmland were destroyed. Tropical Storm Owen (Emang) Forming as a tropical disturbance southwest of Kosrae on June 21. Moving west-northwest, the system gradually became better organized. On June 28, the disturbance had organized into a tropical depression. Recurving east of the Philippines and Taiwan, Owen developed into a tropical storm, reaching its maximum intensity on June 29. Thereafter, east-northeasterly winds aloft led to vertical wind shear which weakened Owen. While moving north-northeast towards southern Japan, the system devolved into a low level circulation devoid of thunderstorms, and dissipated on July 2. Super Typhoon Peggy (Gading) Typhoon Peggy, which developed on July 3 east of the Philippines, steadily strengthened to reach a peak of super typhoon on July 7. As Peggy continued westward, it slowly weakened, and hit northeastern Luzon on July 9 as a typhoon. A slight weakening of the subtropical ridge brought Peggy more northward, where it hit southeastern China as a tropical storm on the July 11. In Hong Kong, winds gusted to at Tate's Cairn and rainfall totals reached at Tai Mo Shan. Peggy's fury resulted in 333 casualties and US$2.5 million (1986 dollars) in damage from torrential flooding. Typhoon Roger (Heling) An upper-level low retrograded westward across the tropical Pacific Ocean beginning on July 4. On July 8, a tropical disturbance formed southeast of the upper low southwest of Enewetak Atoll. The system moved westward, slowly organizing. Becoming a tropical depression on July 13, the small system turned northwest, recurving gradually around a subtropical ridge to its east and northeast. The system strengthened into a tropical storm later on July 13, and a typhoon on July 14 to the south of
