Typhoon Roy,known in the Philippines as Typhoon Asiang, [1] was the second-most intense January tropical cyclone on record in the Western Pacific basin. Forming out of an area of disturbed weather on January 7,1988,Roy quickly intensified as it moved through the Marshall Islands. By January 9,the storm intensified into a typhoon and attained its peak intensity the following day. At its peak,sustained winds reached 215 km/h (135 mph). [nb 1] Slight weakening took place before the storm moved through the Mariana Islands. Continuing westward,the system eventually struck the Philippines as a minimal typhoon before dissipating over the South China Sea on January 19.
Throughout its track,Typhoon Roy was responsible for two fatalities and $28.5 million (1988 USD) in losses,mainly in the Mariana Islands. Light to moderate structural damage took place across the Marshall Islands as the system moved through the region as a tropical storm. On January 12,the typhoon caused widespread damage to Guam and Rota as it brushed the two islands,destroying at least 200 homes.
Typhoon Roy originated from an area of disturbed weather in early January 1988 in the central Pacific. Above average sea surface temperatures in the area allowed for gradual development as convection increased. By January 6, the JTWC began monitoring the disturbance for the possibility of it developing into a tropical cyclone; a mirror system was present in the Southern Hemisphere at the same time. The system south of the equator eventually developed into Tropical Cyclone Anne. [2] By January 7, the Japan Meteorological Agency (JMA) classified the system as a tropical depression; [3] shortly thereafter, the JTWC issued a Tropical Cyclone Formation Alert for the depression. Early on January 8, the JTWC issued their first advisory on Tropical Depression 01W, at which time the system was located near the Marshall Islands. [2]
Tracking nearly due west, the depression was upgraded to Tropical Storm Roy six hours after the first advisory based on satellite data. [2] By this time, the JMA had already classified Roy as a tropical storm. [3] Continued deepening took place as the storm moved through the Marshall Islands; weather radar data from Kwajalein Atoll indicated the formation of an eye several hours after Roy was named; this was later supported by satellite information on January 9, at which time the storm was upgraded to a typhoon. Embedded within a moderate east-southeasterly flow along the south side of a subtropical ridge, the typhoon accelerated, obtaining a forward speed of 40 km/h (25 mph). [2]
During the afternoon of January 10, Roy reached its peak intensity as a low-range Category 4-equivalent typhoon on the Saffir–Simpson hurricane scale, attaining peak winds of 215 km/h (135 mph). [2] At the same time, the JMA estimated that the storm attained peak winds of 155 km/h (95 mph) along with a barometric pressure of 940 mbar (hPa; 27.76 inHg). [3] Upon reaching this strength, the storm was situated roughly 945 km (587 mi) east-southeast of Guam. Over the following few days, Roy gradually slowed and weakened as it neared the Mariana Islands. The storm made its closest approach to the islands early on January 12, passing within 14 km (8.7 mi) south of Rota. As the storm passed through the region, a new ridge built east of the typhoon, causing Roy to temporarily track southwestward before resuming a westward movement. [2]
Moving along the southern edge of the ridge, Roy accelerated again as it headed towards the Philippines. [2] On January 14, the storm crossed 135°E, prompting the Philippine Atmospheric, Geophysical and Astronomical Services Administration to issue advisories on Roy, assigning it with the local name Asiang. [1] As it neared the country, wind shear began to increase, resulting in further weakening. On January 16, Roy made landfall in the Bicol Region as a minimal typhoon before weakening to shear and increased friction with the mountains of the Philippines. Later that day, the system weakened to a tropical storm before entering the South China Sea. The JTWC downgraded Roy to a tropical depression during the afternoon of January 17 and ceased issuing advisories early the next day. [2] However, the JMA continued to monitor Roy as a tropical storm until the morning of January 18 and declared the system dissipated early on January 19, at which time the depression was situated roughly 700 km (430 mi) east-northeast of Ho Chi Minh City, Vietnam. [3]
On January 8, Roy passed near the Majuro island chain in the Marshall Islands as a minimal tropical storm. Sustained winds of 65 km/h (40 mph) and gusts up to 85 km/h (55 mph) affected the area, resulting in minor structural damage. Later that day, the intensifying storm passed close to Kwajalein Atoll, bringing strong winds and large swells. Moderate structural damage took place on Kwajalein Island where winds gusted up to 105 km/h (65 mph). Just to the north, more severe damage was recorded on Ebeye Island where low-lying areas were inundated by waves between 6.1 and 6.7 m (20 and 22 ft). [2] Approximately one third of the homes on Ebeye were destroyed by the storm. [4] One person was killed and damage was estimated at $5 million (1988 USD). [2] An estimated 3,500 people were left homeless as a result of Roy in the Marshall Islands. [5]
Ahead of Roy's arrival in the Mariana Islands and Guam, the public was given sufficient warning by the local disaster preparedness team. [2] An estimated 1,200 people evacuated to shelters across Guam and all flights to and from the island were canceled for January 12. [6]
On January 12, Typhoon Roy passed through the Mariana Islands and Guam, causing moderate structural damage and extensive crop losses. On Guam alone, agricultural losses reached $23.5 million (1988 USD; $60.5 million2024 USD). Most structural damage was limited to broken windows on the island. Located within 15 km (9.3 mi) of Roy's eye during its passage of the Mariana Islands, Rota received the worst damage from the cyclone. Winds on the island gusted up to 193 km/h (120 mph), wreaking havoc to structures and vegetation. [2] At least 200 of the 450 of homes on Rota were destroyed and the remainder were damaged; [7] 95% of the power poles fell across the island, resulting in severe disruption to daily life. [2] Roughly 80% of the concrete homes had their windows blown out. [8] Four people were injured after the roof of one building was blown into another where people had sought shelter. [2] One person died after suffering a heart attack induced by the storm. [9] In the wake of the storm, the Federal Emergency Management Agency declared a state of emergency for Guam. [7] [10]
The last area affected by Typhoon Roy was the Philippines, which was struck by the storm on January 16. [2] Prior to the storm's arrival, typhoon warnings were raised for 29 provinces in the country, including the capital city of Manila. [11] In the Bicol Region, winds likely reached typhoon intensity; however, no known damage took place in the area. Continuing westward, the Roy brought gale-force winds to parts of southern Luzon before moving into the South China Sea. [2] [12] Low-lying areas in the storm's path were flooded by heavy rains and strong winds downed power lines in Sorsogon. [13]
Since the JMA kept reliable records in 1951, Roy became the ninth known typhoon to develop during the month of January as well as the second most intense during the month, attaining a minimum pressure of 940 mbar (hPa; 27.76 inHg). It also attained the second-highest sustained winds during January, estimated at 150 km/h (95 mph). [14] According to the JTWC, Roy was the third-most intense typhoon during the month, attaining peak winds of 215 km/h (135 mph) and an estimated pressure of 927 mbar (hPa; 27.37 inHg). [15] In addition to intensity records, Typhoon Roy also was an unusually long-lived storm, spanning 12 days from formation to dissipation. This ranks it as the second-longest lived storm during January, just 12 hours short of Typhoon Alice in 1979. [16]
Due to the severity of damage wrought by Typhoon Roy, the name was retired following its usage and replaced with Ryan. [17] Since minimal damage took place in the Philippines, the name Asiang was not retired and was used again in 1992, 1996 and 2000 seasons, respectively. [1]
Typhoon Paka, known in the Philippines as Typhoon Rubing, was an extremely powerful and long-lived storm that devastated Guam and the Marshall Islands in December 1997. One of the strongest Pacific typhoons ever recorded in the month of December, Paka was the last tropical cyclone of the 1997 Pacific hurricane and typhoon seasons and the last of a record eleven super typhoons that formed in 1997. Paka, which is the Hawaiian name for Pat, developed on 28 November from a trough well to the southwest of Hawaii. The storm tracked generally westward for much of its duration, and on 7 December it crossed into the western Pacific Ocean. Much of its track was characterized by fluctuations in intensity, and on 10 December the cyclone attained typhoon status as it crossed the Marshall Islands. On 16 December, Paka struck Guam and Rota with winds of 230 km/h (140 mph), and it strengthened further to reach peak winds on 18 December over open waters as the final super typhoon of the year. Subsequently, it underwent a steady weakening trend, and on 23 December Paka dissipated.
The 2004 Pacific typhoon season was an extremely active season that featured the second-highest ACE ever recorded in a single season, second only to 1997, which featured 29 named storms, nineteen typhoons, and six super typhoons. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2004, though most tropical cyclones typically develop between May and October. The season's first named storm and also the first typhoon, Sudal, developed on April 4, later was reached typhoon status two days later, and became the first super typhoon of the year three days later. The season's last named storm, Noru, dissipated on December 22.
The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.
The 2002 Pacific typhoon season was a slightly above average Pacific typhoon season, producing twenty-six named storms, fifteen becoming typhoons, and eight super typhoons. It had an ACE over 400 units, making it one of the most active seasons worldwide. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2002, though most tropical cyclones typically develop between May and October. The season's first named storm, Tapah, developed on January 11, while the season's last named storm, Pongsona, dissipated on December 11. The season's first typhoon, Mitag, reached typhoon status on March 1, and became the first super typhoon of the year four days later.
The 1997 Pacific typhoon season was a record-breaking season featuring eleven tropical cyclones reaching super typhoon intensity, tying the record with 1965 with the most intense tropical cyclones globally, and was the ninth and last consecutive year of above-average tropical cyclone activity that started in 1989. Its extremely high activity produced highest ACE index ever index recorded in a single tropical cyclone season. In addition, this season had ten Saffir-Simpson Category 5-equivalent tropical cyclones, the most ever recorded, even greater than the 2005 Atlantic hurricane season, and 2020 Atlantic hurricane season, for Category 4, which had nearly half of the amount. The 1997–98 El Niño event was a contributing factor to this unusually high activity. Despite this, the season produced an average number of tropical storms, spawning 28 tropical storms.
The 1992 Pacific typhoon season was the fourth consecutive above-average season, producing 31 tropical storms, 16 typhoons and five super typhoons. It had no official bounds; it ran year-round in 1992. Despite this, 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.
The 1988 Pacific typhoon season was a very active season in terms of named storms, though it only featured 11 typhoons and 1 super typhoon. It had no official bounds; it ran year-round in 1988, but most tropical cyclones formed between May and November. Tropical storms that 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.
The 1987 Pacific typhoon season was a below average season, though it featured a relatively high amount of typhoons. It had no official bounds; it ran year-round in 1987, but most tropical cyclones formed between May and November. Tropical storms that formed in the entire 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.
The 1980 Pacific typhoon season was a slightly-below average season when compared to the long-term average, though it featured several intense storms. It ran year-round in 1980, but most tropical cyclones formed between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. A total of 28 tropical depressions formed this year in the Western Pacific, of which 24 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. Beginning in March, tropical cyclones formed in each subsequent month through December. Of the 24 named storms, 15 storms reached typhoon intensity, of which 2 reached super typhoon strength.
Typhoon Pongsona was the last typhoon of the 2002 Pacific typhoon season, and was the second costliest United States disaster in 2002, only behind Hurricane Lili. The name "Pongsona" was contributed by North Korea for the Pacific tropical cyclone list and is the Korean name for the garden balsam. Pongsona developed out of an area of disturbed weather on December 2, and steadily intensified to reach typhoon status on December 5. On December 8 it passed through Guam and the Northern Mariana Islands while at peak intensity, with 10-minute sustained winds of 175 km/h (110 mph). It ultimately turned to the northeast, weakened, and became extratropical on December 11.
Typhoon Isa was the first of a record eleven super typhoons to occur during the 1997 Pacific typhoon season. The second tropical cyclone of the season, Isa developed from a disturbance in the monsoon trough near the Caroline Islands on April 12. It moved erratically at first, though after attaining tropical storm status it curved westward due to the subtropical ridge to its north. Isa very gradually intensified, and on April 20 the typhoon reached peak 1-min winds of 270 km/h (170 mph), as reported by the Joint Typhoon Warning Center; Japan Meteorological Agency reported maximum 10-min winds of 155 km/h (95 mph). After turning northward, it accelerated to the northeast, and merged with a larger extratropical cyclone on April 24.
Typhoon Tingting was a destructive tropical cyclone that produced record-breaking rains in Guam. The eighth named storm of the 2004 Pacific typhoon season, Tingting originated from a tropical depression over the open waters of the western Pacific Ocean. The storm gradually intensified as it traveled northwest, becoming a typhoon on June 28 and reaching its peak the following day while passing through the Mariana Islands. After maintaining typhoon intensity for three days, a combination of dry air and cooler sea surface temperatures caused the storm to weaken as it traveled northward. On July 1, the storm passed by the Bonin Islands, off the coast of Japan, before moving out to sea. By July 4, Tinting had transitioned into an extratropical cyclone. The remnants were last reported by the Japan Meteorological Agency, the Regional Specialized Meteorological Center for the western Pacific basin, near the International Date Line on July 13.
Typhoon Choi-wan was a powerful typhoon that became the first Category 5-equivalent super typhoon to form during the 2009 Pacific typhoon season. Forming on September 11, 2009, about 1,100 km (700 mi) to the east of Guam, the initial disturbance rapidly organized into a tropical depression. By September 12, the depression intensified into a tropical storm, at which time it was given the name Choi-wan. The following day, rapid intensification took place through September 14. Choi-wan attained its peak intensity on September 15, as it moved through the Northern Mariana Islands with the Japan Meteorological Agency reporting peak 10-minute sustained winds of 195 km/h (121 mph). Additionally, the Joint Typhoon Warning Center reported the storm to have attained 1-minute sustained winds of 260 km/h (160 mph). The typhoon remained very powerful until September 17 when the storm's outflow weakened. The typhoon underwent an eyewall replacement cycle, leading to intensity fluctuations. By September 19, Choi-wan rapidly weakened as strong wind shear caused convection to diminish. The following day, the system transitioned into an extratropical cyclone and dissipated several hours later over open waters.
Typhoon Melor, known in the Philippines as Super Typhoon Quedan, was a powerful typhoon that hit Japan in early October 2009, causing significant damage. As part of the 2009 Pacific typhoon season, Melor formed as a tropical depression on September 29 and rapidly intensified into a Category 4-equivalent typhoon just three days later. Subsequently, on October 4, Melor became the second Category 5-equivalent super typhoon to form in the season. During the next days, the typhoon would interact with Typhoon Parma southeast of Taiwan, causing Parma to be almost stationary over northern Luzon and drop near-records of rainfall there. Afterwards, Melor gradually weakened in its approach to Japan, making landfall on October 7. As the storm exited Japan during the next day, it transitioned into an extratropical cyclone. The remnants of Melor were absorbed by a newly-formed extratropical cyclone near Alaska, which strengthened significantly and impacted the West Coast of the United States on October 13.
Typhoon Mirinae, known in the Philippines as Typhoon Santi, was the 34th depression and the 14th typhoon in the 2009 Pacific typhoon season. It came several weeks after Typhoons Ketsana and Parma devastated the Philippines, thus adding additional damage wrought by the two preceding typhoons.
Typhoon Keith was an extremely powerful tropical cyclone and the tenth of a record eleven super typhoons to develop during the unusually intense 1997 Pacific typhoon season. Originating from a near-equatorial trough on October 26, the precursor depression to Keith slowly organized into a tropical storm. After two days of gradual strengthening, the storm underwent a period of rapid intensification on October 30 as winds increased to 195 km/h (121 mph). On November 1, the storm further intensified into a super typhoon and later attained peak winds of 285 km/h (177 mph). The following day, the powerful storm passed between Rota and Tinian in the Northern Mariana Islands. After fluctuating in strength over the following few days, a steady weakening trend established itself by November 5 as the typhoon accelerated towards the northeast. On October 8, Keith transitioned into an extratropical cyclone and was last noted early the following day near the International Dateline.
Typhoon Gay, known in the Philippines as Typhoon Seniang, was the strongest and longest-lasting storm of the 1992 Pacific typhoon season and most intense globally in 1992. It formed on November 14 near the International Date Line from a monsoon trough, which also spawned two other systems. Typhoon Gay later moved through the Marshall Islands as an intensifying typhoon, and after passing through the country it reached its peak intensity over open waters. The Joint Typhoon Warning Center (JTWC) estimated peak winds of 295 km/h (183 mph) and a minimum barometric pressure of 872 mb (25.8 inHg). However, the Japan Meteorological Agency (JMA), which is the official warning center in the western Pacific, estimated winds of 205 km/h (127 mph), with a pressure of 900 mbar (27 inHg). Gay weakened rapidly after peaking because of interaction with another typhoon, and it struck Guam with winds of 160 km/h (99 mph) on November 23. The typhoon briefly re-intensified before weakening and becoming extratropical south of Japan on November 30.
Typhoon Lynn, more commonly known in the Philippines as Typhoon Pepang, was responsible for the worst flooding in Taiwan in 40 years. Typhoon Lynn originated from an area of disturbed weather in the central north Pacific in mid-October 1987. On October 15, the system was upgraded into a tropical storm. Moving west-northwest, it slowly deepened over the next few days, though the intensification process briefly stopped on October 15. Two days later, Lynn was upgraded into a typhoon, while passing northwest of Guam. Lynn maintained low-end typhoon strength until October 19, when the storm began to rapidly intensify. On October 21, Lynn attained its peak intensity while tracking towards the west. Weakening then commenced soon after Lynn interacted with Luzon. However, the core of the typhoon remained well offshore both the Philippines and Taiwan. On October 25, Lynn weakened to a severe tropical storm. Three days later, it dissipated, though its remains later brought rain to China.
Typhoon Dolphin was a powerful tropical cyclone that produced the first typhoon-force winds on Guam since Typhoon Pongsona in 2002. The seventh named storm of the 2015 Pacific typhoon season, Dolphin formed on May 6 in the vicinity of the Federated States of Micronesia (FSM). Moving eastward at first, the storm slowly organized before beginning a north and west-northwest trajectory. Dolphin intensified into a typhoon before passing between Guam and Rota on May 15, producing typhoon-force winds on both islands. It later rapidly intensified as it curved to the north. The American-based Joint Typhoon Warning Center (JTWC) designated Dolphin as a super typhoon, while the Japan Meteorological Agency (JMA) estimated 10 minute sustained winds of 185 km/h (115 mph). Dolphin turned to the northeast and weakened, becoming extratropical on May 20 and exiting the western Pacific basin on May 24.
Tropical Storm Bavi, known in the Philippines as Tropical Storm Betty, was an early-season tropical storm in the 2015 Pacific typhoon season. The system influenced the trade winds over the Pacific Ocean and was partially responsible for one of the strongest trade wind reversals ever observed. The system was first noted as a tropical disturbance during March 8, 2015, while it was located to the southeast of Kwajalein Atoll in the Marshall Islands. Over the next couple of days the system moved north-westwards through the Marshall Islands, before it was classified as a tropical depression during March 10. The system subsequently moved north-westwards and continued to develop further, before it was classified as the third tropical storm of the 2015 Pacific typhoon season and named Bavi by the Japan Meteorological Agency (JMA) during March 11. After continuing its north-westwards movement, the system peaked as a tropical storm during March 14, before it started to weaken as it approached the Mariana Islands. The system subsequently passed over Guam during the next day, before continuing its west-northwestwards movement as it gradually weakened over the next few days. The system entered the Philippine area of responsibility, where it was named Betty by PAGASA during March 17 as the system weakened into a tropical depression. The system was subsequently last noted during March 21, as it dissipated over the Philippines.
