Typhoon Mike
Typhoon Mike, known in the Philippines as Typhoon Ruping, of 1990 was the strongest typhoon to hit the Philippines since Typhoon Irma in 1981 and Typhoon Nina in 1987. Forming from an area of persistent convection over the Caroline Islands, Mike was first designated on November 6, 1990 and moved generally westward. Later that day, the depression strengthened to Tropical Storm Mike near Yap. Mike became a typhoon early on November 9, and subsequently entered a period of rapid deepening. Late on November 10, the typhoon reached its maximum intensity of , as estimated by the Japanese Meteorological Agency. After weakening slightly, Mike made landfall in the central Philippines. The storm weakened considerably due to land interaction, only to briefly re-intensify on November 14. Typhoon Mike turned west-northwest and later north-northwest, avoiding land interaction with Vietnam. Vertical wind shear increased, and on November 15, Mike weakened below typhoon intensity. Early the next day, the storm passed over western Hainan Island, and degraded to a tropical depression that night. After briefly emerging into the Gulf of Tonkin, Mike passed over Northern Vietnam and southern China, where it dissipated on November 18. During its formative stages, Mike passed just north of Palau.
