Typhoon Betty, known in the Philippines as Typhoon Aring, was the strongest typhoon to strike the Philippines in ten years. An area of disturbed weather developed on October 27, 1980, near Truk Atoll. After turning east from south, the disturbance was classified as a tropical storm on October 29 as it passed near Guam, causing only minor damage. Following a turn to the west-northwest, Betty attained typhoon intensity the next day. On November 4, Betty peaked in intensity. Later that day, Betty moved ashore over Luzon, introducing a rapid weakening trend. Over land, Betty then began to turn north due to a weakening subtropical ridge to its north and a trough offshore Taiwan. By November 8, Betty, after moving offshore, had completed its transition into an extratropical cyclone, and dissipated that same day.
Across the Philippines, 101 casualties were reported. More than 29,000 homes were damaged and over 5,000 houses were leveled, resulting in 229,000 people homeless. A total of 70 villages sustained flooding. In all, Typhoon Betty inflicted $181 million (1980 USD) in damage, with $43.1 million from crops, $116 million from public property, and $21.7 million from private property. Following the storm, 11 provinces were declared a disaster area.
Typhoon Betty, one of five tropical cyclones to develop in the Western Pacific basin during October 1980, 22. Five days later, the disturbance began to show signs of organization while it was located to the south of Truk Atoll. At 00:00 UTC on October 28, the Japan Meteorological Agency (JMA) upgraded the system to a tropical depression. Based on surface observations and data from a Hurricane Hunter aircraft, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA) at 08:00 UTC. After initially moving south, the disturbance turned east as it approached Truk Atoll. Following an increase in the disturbance's organization, the JTWC classified the system as Tropical Depression 25 on October 29 while the JMA upgraded it to a tropical storm. Six hours later, the JTWC upgraded the depression into Tropical Storm Betty.originated from a tropical disturbance that was first noticed on October
After moving erratically during its formative stages, Tropical Storm Betty accelerated towards the west-northwest as it passed south of Guam. 29, the JMA designated Betty a severe tropical storm. Twenty-four hours later, the JTWC upgraded Betty into a typhoon, with the JMA doing the same at 00:00 UTC on October 31. Twelve hours later, the JTWC raised the winds to 160 km/h (100 mph), equal to a low-end Category 2 hurricane on the United States-based Saffir-Simpson Hurricane Wind Scale (SSHWS). On November 1, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also began to track the storm and assigned it with the local name Aring. After turning due west, Betty continued to intensify, although a Hurricane Hunter penetration later on November 1 indicated no eyewall. Early on November 2, synoptic data showed a shortwave trough moving off Asia. As such, the JTWC expected Betty to re-curve near the 125th meridian east. Instead, Typhoon Betty abruptly turned southwestward. On November 3, the trough moved quickly eastward north of the system, closing Betty's window for re-curvature. Following the formation of an eye, the JMA estimated that the typhoon peaked in intensity the next day, with winds of 185 km/h (115 mph) and a barometric pressure of 925 mbar (27.3 inHg). Later that day, the JTWC estimated an intensity of 225 km/h (140 mph).Late on October
By 00:00 UTC on November 4, the JTWC amended its forecast for Typhoon Betty, projecting it to move northwest into southern Luzon and China. At 16:00 UTC that day, Betty made landfall in central Luzon south of Cape San Ildefonso, with the JTWC reporting winds of 225 km/h (140 mph) and the JMA estimating winds of 185 km/h (115 mph). As Betty weakened over land, a subtropical ridge to Betty's north broke down. Betty began to turn north in response to a shortwave through offshore Taiwan. According to both the JTWC and JMA, the cyclone had weakened below typhoon intensity once it moved back over water. Betty never regained its past intensity as it drifted northward, and at 00:00 UTC on November 8, Betty was declared an extratropical system by the JTWC. Twelve hours later, the JMA ceased tracking the system, while the cyclone was located southeast of Honshu.
During its formative stages, Betty passed near Guam, where strong winds caused major crop damage and downed power lines. On October 30, the Antonio B. Won Pat International Airport was closed. Although there was no major damage on Guam, typhoon alerts were issued for Yap and Palau.
Prior to landfall, most government offices were closed throughout Luzon, where storm warnings were also posted. people lost their homes due to flooding. Seven children were rescued in Tayug. In the Tarlac province, damage to rice totaled $2.7 million. A total of 455 homes were destroyed and 2,000 others were damaged across the Aurora province. The capital city of Manila suffered minor street flooding, especially in low-lying suburbs. Although 750 people were evacuated to shelter, the capital avoided the brunt of the typhoon. The Cagayan River in the Isabela province overflowed its banks, which resulted in 30,000 citizens homeless. In the same province, half the town of Cabagan was left underwater. In Cagyan Valley, 8,000 pupils were stranded. All roads leading to the town of Baler in the Quezon province were impassable. Five people, three of whom were children, drowned in the province of Nueva Ecija. A landslide occurred in Maliling, a village in Nueva Vizcaya province, resulting in 50 fatalities. Twenty-two bodies were recovered while the others were feared dead.Philippine Airlines cancelled all domestic and some international flights. Upon making landfall in the Philippines, press reports indicated that Betty became the strongest typhoon to strike the country in a decade. In the Albay province, 440
Overall, 101 people died in the Philippines. A total of 245,064 families were listed as affected, meaning that they were evacuated or homeless. Over 29,000 homes were damaged and more than 5,000 houses were destroyed, leaving 290,000 people homeless. Seventy villages were flooded. Damage was estimated at $181 million (₱1.36 billion), with $43.1 million from crops (₱324 million), $116 million from public infrastructure (₱871 million), and $21.7 million (₱163 million) from private infrastructure. At the time, Betty was the third costliest tropical cyclone to affect the Philippines, behind Typhoon Joan and Typhoon Kate in 1970 and Typhoon Rita in 1978. The typhoon hit the same areas were affected by Typhoon Joe and Typhoon Kim earlier that summer. Following the storm, army trucks and a C-47 plane were mobilized to carry relief goods. Eleven provinces and one hundred-thirteen towns were declared a disaster area by President Ferdinand Marcos.
Typhoon Mike, known in the Philippines as Typhoon Ruping, of 1990 was the strongest typhoon to hit the Philippines since Typhoon Irma in 1981. 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 115 mph (185 km/h), as estimated by the Japanese Meteorological Agency. After weakening slightly, Mike made landfall in the central Philippines, after weakening slightly. 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.
Typhoon Nina, known in the Philippines as Typhoon Sisang, was the most intense typhoon to strike the Philippines since Typhoon Irma in 1981. Typhoon Nina originated from an area of convection near the Marshall Islands in mid-November 1987. It gradually became better organized, and on November 19, was first classified as a tropical cyclone. Moving west-northwest, Nina attained tropical storm intensity that evening. Late on November 20, Nina passed through the Chuuk Lagoon. After a brief pause in intensification, Nina intensified into a typhoon on November 22. Two days later, the typhoon intensified suddenly, before attaining its peak 10 minute intensity of 165 km/h (105 mph). During the afternoon of November 25, Nina moved ashore in southern Luzon at the same intensity. It gradually weakened over land, before entering the South China Sea and turning to the north. By November 30, Nina dissipated.
Typhoon Dot, known in the Philippines as Typhoon Saling, was the strongest storm of the 1985 season. Dot originated from a small area of thunderstorm activity in early to mid October. The system was first classified on October 11, and steadily intensified over the next few days. Dot attained typhoon strength on October 15, and subsequently entered a period of explosive deepening, which was not anticipated by forecasters. The next day the intensification rate slowed, but that evening, Dot attained its maximum intensify. A steady weakening trend began on October 17, though the system maintained typhoon intensity through the passage of the Philippines. After entering the South China Sea late on October 18, Dot briefly re-intensified, only to weaken as it approached Vietnam. On October 21, Dot struck Vietnam while still a typhoon, but dissipated the next day over the high terrain of the nation.
Typhoon Alex, known in the Philippines as Typhoon Etang, affected the Taiwan, China, and South Korea during July 1987. Typhoon Alex developed from the monsoon trough that spawned a tropical disturbance late on July 21 southwest of Guam which organized into a tropical depression shortly thereafter. The system steadily became better organized, and the next day, a tropical depression had developed. Satellite intensity estimates gradually increased, and on July 23, the depression intensified into Tropical Storm Alex. After initially tracking west-northwest, Tropical Storm Alex started tracking northwest. An eye developed on July 24, and on the next day, Alex was classified as a typhoon, when Alex attained its peak intensity of 120 km/h (75 mph) and a minimum barometric pressure of 970 mbar (29 inHg). Alex weakened while tracking more northward, though interaction with Taiwan resulted in a more westward track starting on July 27. The storm struck near Shanghai as a tropical storm, and weakened over land, although it remained identifiable through August 2.
Typhoon Clara, known in the Philippines as Typhoon Rubing, left flooding in the northern Philippines and southern China during September 1981. An area of disturbed weather was first detected on September 11 near Ponape. After moving westward, the system gradually became better organized and thunderstorm activity increased. On September 16, the system attained tropical storm status. Two days later, Clara attained typhoon intensity and subsequently began to deepen at a faster rate. On September 19, Clara reached maximum intensity, before making landfall along the northern tip of Luzon. Clara steadily weakened after interacting with land, but by late on September 20, Clara leveled off in intensity over the South China Sea. The next day, Clara moved ashore to the east-northeast of Hong Kong while still at typhoon intensity before rapidly dissipating over land.
Typhoon Irma, known in the Philippines as Typhoon Daling, affected the Philippines in late June 1985. Typhoon Irma originated from a monsoon trough situated near Guam in the Western Pacific Ocean. It slowly developed, with insufficient organization delaying classification as a tropical cyclone. By June 24, organization improved as the system encountered favorable conditions aloft and the disturbance attained tropical storm intensity the next day. Moving west, Irma gradually deepened, and on June 28, it was believed to have attained typhoon intensity. On the morning of June 27, Irma was upgraded into a typhoon. After passing northeast of the Philippines, Typhoon Irma attained its peak intensity on June 29. Accelerating to the north and then the northeast, Irma steadily weakened as it encountered significantly less favorable conditions. The typhoon made landfall in central Japan on June 30. Irma weakened below typhoon intensity the next day, and later on July 1, Irma transition into an extratropical cyclone. The remnants of the cyclone were tracked until July 7, when it merged with an extratropical low south of the Kamchatka Peninsula.
Typhoon Nepartak, known in the Philippines as Typhoon Weng, was a modest tropical cyclone that struck the central Philippines and the southern China island of Hainan in November 2003. Forming as a tropical depression on November 11 between Yap and Guam, the system moved westward and slowly intensified. It received the name Nepartak midday on November 12 from the Japan Meteorological Agency, becoming the 20th named storm of the 2003 Pacific typhoon season. On November 13, Napartak struck Samar in the Philippines and bisected the island chain. Up to four million people lost power, and transportation ground to a halt; over 5,000 individuals became stranded on ships forced to stay in port during the tropical storm. It was reported that 13 individuals lost their lives to the storm in the Philippines.
Tropical Storm Tess known in the Philippines as Tropical Storm Welpring was the second of three tropical cyclones to directly impact the Philippines in a two-week time frame in 1988. An area of disturbed weather near the Philippines was first observed on November 1. Following an increase in organization, the disturbance was designated as a tropical cyclone on November 4. Moving west, Tess steadily strengthened due to favorable conditions aloft. During the evening of November 5, Tess was estimated to have achieved its highest intensity, with winds of 115 km/h (70 mph). Rapid weakening then ensured as Tess neared Vietnam, and after making landfall in the country on November 6, Tess dissipated the next day.
Typhoon Kim, known in the Philippines as Typhoon Osang, was the second typhoon in a week to directly affect the Philippines during July 1980. Like Typhoon Joe, Kim formed from the near equatorial monsoon trough in the northwestern Pacific Ocean on July 19. The disturbance tracked quickly westward-northwest underneath a subtropical ridge, reaching tropical storm strength on the July 21 and typhoon strength on July 23. After developing an eye, Kim began to rapidly intensify, and during the afternoon of July 24, peaked in intensity as a super typhoon. Several hours later, Kim made landfall over the Philippines, but the storm had weakened considerably by this time. Throughout the Philippines, 40 people were killed, 2 via drownings, and 19,000 others were directly affected. A total of 12,000 homes were destroyed and 5,000 villages were flooded. Less than a week earlier, the same areas were affected by Joe; however, Kim was considered the more damaging of the two typhoons. Land interaction took its toll on Kim, and upon entering the South China Sea, the storm was down below typhoon intensity. Kim continued northwestward but its disrupted circulation prevented re-intensification, and it remained a tropical storm until hitting southern China July 27 to the northeast of Hong Kong, where only slight damage was reported. Later that day, Kim dissipated.
Typhoon Gerald, known in the Philippines as Typhoon Neneng, affected the Philippines, Taiwan, and China during September 1987. A tropical depression developed on September 4, and within 24 hours, intensified into a tropical storm. After initially moving erratically within the Philippine Sea, Gerald moved west-northwest and then northwest while steadily deepening. Gerald obtained typhoon intensity on September 8, and the following day, attained maximum intensity. Shortly thereafter, the typhoon skirted southwestern Taiwan, which resulted in a steady weakening trend. On September 10, Gerald moved ashore north of Hong Kong near Amoy. Gerald dissipated the next day.
Typhoon Cary, known as Typhoon Ising in the Philippines, was the second of two tropical cyclones to affect Vietnam in a week. An area of disturbed weather developed southwest of Pohnpei on August 6, 1987. The system initially remained disorganized, but by August 14, Cary had attained tropical storm intensity. After initially moving north-northwest, Cary turned west-northwest, although intensification was slow to occur. On August 15, Cary was upgraded into a typhoon, and on August 17, the typhoon peaked in intensity. Typhoon Cary then made landfall in northern Luzon while at peak intensity. Across the Philippines, 954 houses were damaged and an additional 89 were destroyed, which left 55,567 people, or 13,247 families that were either homeless or otherwise sought shelter. Five people died in the country while damage totaled $5.58 million (1987 USD), including $1.45 million from agriculture and $4.13 million from infrastructure. The storm weakened over land, but re-intensified into a typhoon over the South China Sea. On August 21, Typhoon Cary passed just south of Hainan, where hundreds of homes were damaged but no fatalities occurred, and subsequently entered the Gulf of Tonkin. The storm weakened as it approached Vietnam, and on August 23, the storm dissipated inland over Laos. Across Vietnam, almost 40,000 ha of land were flooded or destroyed. Twenty people were killed and many others were injured.
Typhoon June, also known in the Philippines as Typhoon Maring, was the first of two tropical cyclones to affect the Philippines in a one-week time span in August 1984. June originated from an area of convection that was first witnessed on August 15 in the Philippine Sea. Despite initial wind shear, the area intensified into a tropical storm three days later as it tracked westward. After tracking over Luzon, June entered the South China Sea on August 30. Despite remaining poorly organized, June re-intensified over land, and it was estimated to have briefly attained typhoon intensity before striking China, just to the east of Hong Kong, at maximum intensity, although its remnants were last noticed on September 3.
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 Joe, known in the Philippines as Typhoon Nitang, affected the Philippines, China, and Vietnam during July 1980. An area of disturbed weather formed near the Caroline Islands on July 14. Shower activity gradually became better organized, and two days later, the system was upgraded into a tropical depression. On July 18, the depression was classified as Tropical Storm Joe. Initially, Joe moved northwest, but began to turn to the west-northwest, anchored by a subtropical ridge to its north. Joe started to deepen at a faster clip, and attained typhoon intensity on July 19. The eye began to clear out, and the next day, Joe reached its highest intensity. Shortly thereafter, Joe moved ashore the Philippines. There, 31 people were killed and 300,000 others were directly affected. Around 5,000 homes were destroyed, resulting in an additional 29,000 homeless. Damage in the nation was estimated at $14.5 million (1980 USD).
Typhoon Faith, known in the Philippines as Typhoon Norming, struck both the Philippines and Vietnam during December 1998. A tropical disturbance developed within the vicinity of the western Caroline Islands during early December. At midday on December 8, the system developed into a tropical depression. Tracking northwest at a brisk pace, the depression gradually intensified, and was upgraded into a tropical storm at noon on December 9. Quickly intensifying, Faith turned to the west-northwest, and after tracking near Samar Island on the evening of December 10, Faith attained typhoon intensity. After clipping the northern tip of Palawan Island, the typhoon entered the South China Sea at peak intensity. Across the Philippines, 33 people were killed, with 30 others wounded and 36 others listed missing. A total of 6,423 homes were damaged and 3,234 houses were destroyed, leaving more than 20,000 homeless. Damage was estimated at $25.9 million, with $6.82 million from crops, $15.9 million from public infrastructure, and $3.37 million from private infrastructure.
Typhoon Irving, known in the Philippines as Typhoon Ruping, was a mid-season tropical cyclone that affected the Philippines and China during September 1982. An area of disturbed weather developed within the monsoon trough during early September 1982 near Guam. Following an increase in organization, a tropical depression developed on the morning of September 5. Later that day, the depression intensified into Tropical Storm Irving. Irving tracked westward, nearly becoming a typhoon before hitting the central Philippines. There, Irving uprooted trees, downed power and telephone lines, triggered landslides, and forced the cancellation of several domestic airline flights. Irving damaged 7,890 houses in Albay and Sorsogon provinces alone, resulting in 138,500 people homeless. Nation-wide, 65 people were killed, 26 others were hurt, and 29 were rendered missing. A total of 44,383 families or 248,040 residents sought shelter. Moreover, 18,488 homes were damaged and 5,599 others were demolished. Damage in the country was assessed at US$23.3 million, including US$14.2 million in crops. While crossing the island chain, Irving turned northwestward. After entering the South China Sea, Irving continued generally northwest, and became a typhoon on September 11. After developing a well-defined eye, Irving attained its peak intensity of 160 km/h (100 mph) the following day. Land interaction with Hainan Island resulted in a weakening trend, and Irving was downgraded to a tropical storm before striking the southern coast of China on September 15. Across the Leizhou Peninsula, 90% of homes were damaged. Onshore, Irving rapidly weakened and the storm dissipated on September 16.
Typhoon Warren, known in the Philippines as Typhoon Huaning, struck the Philippines and China during July 1988. An area of disturbed weather developed within the vicinity of the Caroline Islands during the second week of July. A tropical depression developed southeast of Guam on July 12, and on the next day, intensified into a tropical storm. Tracking generally west-northwest, Warren deepened into a typhoon on July 14. The storm subsequently entered a period of rapid intensification, commencing with Warren reaching its highest intensity on July 16. The following evening, the typhoon brushed Luzon, resulting in a weakening trend, although Warren was still a typhoon when it made landfall near Shantou. Warren rapidly dissipated inland.
Typhoon Ofelia, known as Typhoon Bising in the Philippines, was the first of two typhoons in 1990 to directly affect the Philippines within a week. Typhoon Ofelia originated from an area of disturbed weather embedded in the monsoon trough situated near the Caroline Islands. Slowly organizing, the disturbance tracked westward, and was designated a tropical depression on June 15. After an increase in convection, the depression was upgraded into a tropical storm on June 17. On June 19, Ofelia turned northwest and after development of a central dense overcast, Ofelia was upgraded into a typhoon late on June 20. After turning north, Ofelia obtained its maximum intensity following the development of an eye. The typhoon skirted past the northeastern tip of Luzon and near the east coast of Taiwan, commencing a rapid weakening trend. On the evening on June 23, Ofelia struck the southern portion of Zhejiang. The storm then began to track north, recurving towards the Korean Peninsula. The storm tracked through the province of Jiangsu, and at 00:00 UTC on June 24, transitioned into an extratropical cyclone, only to merge with a frontal zone on June 25.
Typhoon Percy, known in the Philippines as Typhoon Klaring, was the third tropical cyclone to affect the country in 1990. The fourth and the last tropical cyclone to be formed in June of the 1990 Pacific typhoon season, Typhoon Percy originated from an area of disturbed weather spawned by the Western Pacific monsoon trough on June 20. That same day, the disturbance was classified as a tropical depression as it slowly organized and on June 21, the depression obtained tropical storm intensity. After initially tracking westward, Percy turned towards the southwest while slowly deepening. During this time, Percy affected several of the Carolina Islands. Thirty homes were damaged and airline services were halted in and out of Yap. Farther south-southwest, seven homes were destroyed on the Ngulu Atoll. Furthermore, one boy was killed on Koror, where numerous homes lost their roofs and communication lines were downed. Percy then turned back to the west-northwest and became a typhoon on June 23. It then began to deepen at a faster rate, with Percy attaining its maximum intensity of 145 km/h (90 mph) on June 25. Two days later, on June 27, increased wind shear began to induce a weakening trend and the typhoon brushed Luzon, where eight people were killed and over 30,000 lost their homes. Despite that however, damages in the country was minor.
Typhoon Eli, known in the Philippines as Typhoon Konsing, struck the Philippines and Hainan during mid-July 1992. A weak low pressure system developed in the Philippines Sea on July 7, which became a tropical depression on the next day. The depression tracked west-northwest and strengthened into a tropical storm on July 10. After turning more westward, Eli steadily intensified, and obtained typhoon intensity that evening. The storm attained its highest intensity of 130 km/h (80 mph) early on July 11 before striking northern Luzon. After entering the South China Sea, the storm maintained most of its intensity as it approached Hainan, although agencies disagree on how precisely strong it was. After passing through Hainan late on July 13, Eli passed through the Gulf of Tonkin on the next day before striking Vietnam, where Eli quickly dissipated.
