Which tropical cyclone was the final cyclone to affect the Phillippines during the 1984 Pacific typhoon season?
Typhoon Agnes (1984) Typhoon Agnes, known in the Philippines as Typhoon Undang, was the final tropical cyclone to affect the Philippines during the 1984 Pacific typhoon season. An area of disturbed weather developed near the equator and the Caroline Islands on October 28. Following an increase in organization, the cyclone was designated a tropical storm on October 31. After tracking northwest initially, Agnes turned west-northwest the next day, a course that the system would maintain for the rest of its lifetime. Agnes intensified into a typhoon on November 2, and on November 4, attained peak intensity. The storm then made landfall on Samar Island, part of the Philippines, at that intensity. The storm weakened over land, but re-intensified over the South China Sea; Agnes obtained a secondary peak intensity on November 6. The next day, Typhoon Agnes moved ashore Vietnam while still at typhoon intensity. The storm rapidly deteriorated over land and dissipated by November 8 over Thailand.
Typhoon Amy (1951) Typhoon Amy was an intense and deadly tropical cyclone that struck areas of the central Philippines in December 1951. Impacting the archipelago during the 1951 eruption of Mount Hibok-Hibok, Amy exacerbated the effects of the volcano, greatly increasing the number of resulting deaths. The fifteenth named storm and fourteenth typhoon within the western Pacific Ocean that year, Amy developed from an area of low pressure near the Kwajalein Atoll on December 3. Tracking in a general westward direction, the storm quickly intensified to reach typhoon intensity the next day. However, the typhoon's asymmetricity resulted in a fluctuation of intensity over the following few days. Afterwards, Amy intensified to reach its peak intensity with maximum sustained winds of 220 km/h (140 mph) and a minimum barometric pressure of 950 mbar (hPa; 28.05 inHg) on December 8. Over the ensuing two days, Amy moved over several islands in the central Philippines before emerging in the South China Sea on December 11 as the equivalent of a minimal typhoon. Shortly after, the tropical cyclone executed a tight anticyclonic loop while oscillating in strength several times before eventually weakening and dissipating on December 17, just east of Vietnam.
