Question: Which tropical cyclone was the final cyclone to affect the Phillippines during the 1984 Pacific typhoon season?
Context: The 1984 Pacific typhoon season has no official bounds, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.  These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.  Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center.  Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA.  This can often result in the same storm having two names. 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. Severe Tropical Cyclone Anne was one of the most intense tropical cyclones within the South Pacific basin during the 1980s.  The cyclone was first noted on January 5, 1988 as a weak tropical depression to the northeast of Tuvalu, in conjunction with the future Typhoon Roy in the North-Western Pacific basin.  Over the next few days, the system gradually developed while moving southwestward.  Once it became a tropical cyclone, it was named Anne on January 8.  The next day, Anne rapidly intensified, becoming the fourth major tropical cyclone to affect Vanuatu within four years.  On January 11, Anne peaked in intensity while it was equivalent to a Category 5 on the Saffir–Simpson hurricane wind scale, and a Category 4 on the Australian tropical cyclone intensity scale.  After turning southward on January 12, Anne struck New Caledonia, becoming the strongest tropical cyclone to affect the French Overseas Territory.  The system subsequently weakened as it started to interact with Tropical Cyclone Agi.  Anne weakened into a depression and was last noted on January 14 to the south-east of New Caledonia. The 1948 Pacific typhoon season is an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean.  The season runs throughout 1948, though most tropical cyclones typically develop between May and October.  The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian.  Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones which can often result in a cyclone having two names.  The Japan Meteorological Agency  will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration  assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA.  Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center  are given a number with a "W" suffix. Typhoon Ike, known in the Philippines as Typhoon Nitang, was the deadliest typhoon of the 1984 Pacific typhoon season and crossed the Philippines in September.  This tropical cyclone formed on August 27 in the Philippine Sea, and strengthened as it moved westward into the southern Philippines, becoming a typhoon on August 31.  Typhoon Ike caused extreme wind and flooding damage when it crossed the Philippines, resulting in 1492 fatalities, one of the Philippines' worst natural disaster in modern times, and its worst typhoon since Amy struck the archipelago in 1951.  A total of 200,000 to 480,000 were left homeless.  Emerging from the Philippines as a strong tropical storm, Ike restrengthened as it tracked northwest through the South China Sea across northeast Hainan Island.  Weakening back into a tropical storm, Ike moved inland into mainland China.  In Hong Kong, winds gusted to 49 kn at Tate's Cairn.  Extensive crop damage was experienced in southern China, with Ike becoming the most significant tropical cyclone to strike Guangxi since 1954.  The total damage was reportedly US$111 million (1984 dollars).  The name Ike was retired after this season.  Typhoon Ike was recorded with a 220 km/h gust and an estimated 185 km/h msw in Surigao on September 2 and is one of the intense tropical cyclones and devastating and deadliest to hit the Philippines. Typhoon Judy, known in the Philippines as Typhoon Susang, was the third tropical cyclone to affect Japan during the 1982 Pacific typhoon season.  Forming east of the Philippines in tandem with another system on September 4, the disturbance continued to intensify, and was upgraded into a tropical storm early on September 6 and a typhoon on September 8 while tracking northwestward.  On September 9, Judy attained its peak intensity, with winds of 150 km/h (90 mph).  Thereafter, increased wind shear took a toll on the typhoon, as it turned northward on September 11 in the general direction of Japan under the influence of a mid-latitude cyclone.  Judy passed over southeastern Japan on September 12; by this time, the typhoon had weakened considerably.  Judy became an extratropical cyclone almost immediately thereafter. Typhoon Yancy, known in the Philippines as Typhoon Tasing, was one of the costliest and intense tropical cyclones to strike Japan on record.  Yancy was the sixth typhoon of the annual typhoon season and sixth tropical cyclone overall to impact Japan that year.  Developing out of an area of disturbed weather in the open northwest Pacific on August 29, 1993, the precursor to Yancy tracked westward and quickly intensified to reach tropical storm strength on August 30.  Just two days later, the tropical storm reached typhoon intensity as it recurved towards the northeast.  A period of rapid intensification followed, allowing Yancy to quickly reach super typhoon intensity.  The strong tropical cyclone reached peak intensity on September 2 with maximum sustained winds of 175 km/h (110 mph).  The following day Yancy made its first landfall on Iōjima at nearly the same strength; over the course of the day the typhoon would make three subsequent landfalls on Japanese islands.  Land interaction forced the tropical cyclone to weaken, and after its final landfall on Hiroshima Prefecture, Yancy weakened below typhoon intensity.  After emerging into the Sea of Japan, Yancy transitioned into an extratropical cyclone; these remnants persisted as they meandered in the sea before dissipating completely on September 7. Typhoon Nesat, known in the Philippines as Typhoon Pedring, was the most powerful tropical cyclone to directly impact China since 2005.  It also struck the Philippines during the 2011 Pacific typhoon season, killing 83 people.  It is the 17th named storm, the 11th severe tropical storm, the 7th typhoon and overall, the 30th tropical cyclone to be monitored by the Japan Meteorological Agency(JMA) during the year.  Nesat came exactly two years after Typhoon Ketsana made landfall in the Philippines as the most devastating typhoon in the 2009 Pacific typhoon season with a damage of 1.09 billion and 747 fatalities.  Nesat was also the first of twin tropical cyclones to batter the Philippines within one week during September 2011, the second was Nalgae. Typhoon Soudelor, known in the Philippines as Typhoon Hanna, was the third most intense tropical cyclone worldwide in 2015 after Hurricane Patricia and Cyclone Pam as well as the strongest tropical cyclone of the 2015 Pacific typhoon season.  Soudelor had severe impacts in the Northern Mariana Islands, Taiwan, and eastern China, resulting in 40 confirmed fatalities.  Lesser effects were felt in Japan, South Korea and the Philippines.  The thirteenth named storm of the annual typhoon season, Soudelor formed as a tropical depression near Pohnpei on July 29.  The system strengthened slowly at first before entering a period of rapid intensification on August 2.  Soudelor made landfall on Saipan later that day, causing extensive damage.  Owing to favorable environmental conditions, the typhoon further deepened and reached its peak intensity with ten-minute maximum sustained winds of 215 km/h (130 mph) and a central atmospheric pressure of 900 hPa (mbar; 26.58 inHg) on August 3.  The Joint Typhoon Warning Center assessed one-minute sustained winds at 285 km/h (180 mph), making Soudelor a Category 5-equivalent super typhoon.  Steady weakening ensued thereafter as the storm moved generally west-northwest.  Soudelor made landfall over Hualien, Taiwan, late on August 7 and emerged over in the Taiwan Strait early the next day.  The typhoon soon moved inland over eastern China and degraded to a tropical depression by August 9. The 1949 Pacific typhoon season is an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean.  The season runs throughout 1949, though most tropical cyclones typically develop between May and October.  The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian.  Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones which can often result in a cyclone having two names.  The Japan Meteorological Agency  will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration  assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA.  Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center  are given a number with a "W" suffix.
