Typhoon Vera,known in the Philippines as Typhoon Bebeng, [1] brought significant flooding to the Philippines in July 1983. The monsoon trough spawned a tropical depression on July 12 east of the Philippines. Although the depression was initially slow to organize,the system headed west-northwestward,strengthening to a tropical storm the following day and a typhoon on the July 14. Vera moved onshore early the next day as a minimal typhoon in the Philippines before weakening slightly over the islands. However,Vera managed to restrengthen over the South China Sea while accelerating,later attaining winds of 85 mph (135 km/h). After crossing Hainan while still at peak intensity and moving into the northern portion of the Gulf of Tonkin,Vera gradually weakened before moving ashore in northern Vietnam on July 18. By July 19,Vera had dissipated inland.
Across the Philippines,Typhoon Vera killed 123 and left 60 missing and 45 hurt. Approximately 200,000 people were homeless. The typhoon destroyed 29,054 dwellings and "badly" damaged 5,558 others. A total of 76,346 homes were "partially" damaged. Moreover,24,280 people sought shelter due to Vera. Around 80% of Manila's residents lost power. Many low-lying areas of Manila were underwater while strong winds damaged homes and trees. The province of Bataan sustained the worst damage from the storm and 10 nearby villages were destroyed. Throughout the province,50 people perished,primarily due to drownings. In all,damage totaled $42 million (1983 USD). In addition to the impact on the Philippines,Typhoon Vera claimed three lives in Vietnam and damaged 2,500 houses. Offshore China,a swimmer drowned due to rough seas caused by Vera.
The origins of Typhoon Vera can be traced back to a poorly organized monsoon trough that extended westward from the Philippines to the 160th meridian east in early July 1983. On July 4, the storm developed a persistent circulation. Four days later, a pair of organized areas of convection began to form, one near the 120th meridian east and another close to Guam. A Tropical Cyclone Formation Alert (TCFA) was issued at 0600 UTC on July 10 after the storm developed a well-defined upper-level circulation. However, further development was slow to occur and the TCFA was re-issued 24 hours later despite Hurricane Hunters suggesting that the storm did not have a low-level circulation. Early on July 12, the Joint Typhoon Warning Center (JTWC) upgraded the system into a tropical depression after Hurricane Hunters indicated that the system had developed a closed wind circulation. [2] Twelve hours later, the Japan Meteorological Agency (JMA) classified the system as a tropical storm, bypassing the tropical depression stage. [3] [nb 1]
After tropical cyclogenesis, the depression began to strengthen quite steadily. Meanwhile, the storm slowed down, and by July 13, Vera turned west-northwest and towards the Central Philippines. [2] At 1200 UTC, the JMA estimated that Vera had deepened into a severe tropical storm. [3] Several hours later, the JTWC upgraded the storm into a typhoon. [2] At 0000 UTC on July 14, the JMA upgraded Vera into a typhoon [3] while skirting Samar. [2] Around this time, the Philippine Atmospheric, Geophysical and Astronomical Services Administration also monitored the storm and assigned it with the local name Bebeng. [1] Even though meteorologists from the JTWC anticipated weakening as the storm moved through the island group, this did not occur. Convention gradually increased, until very early on July 15, when the storm started to interact with rugged terrain near Manila. [2] Around this time, the JMA downgraded Vera into a severe tropical storm as it passed very close to Manila Bay. Within the next several hours, the JMA decreased the winds to 105 km/h (65 mph). Late on July 15, the storm began to reintensify [3] and the JTWC upgraded Vera back to typhoon status. [2] Early the following morning, the JMA followed suit. [2] Accelerating, the storm continued to slowly deepen and early on July 27, the JMA reported that Vera reached its peak intensity, with winds of 135 km/h (85 mph). [3] Around this time, the JTWC estimated peak winds of 170 km/h (105 mph), equivalent to a Category 2 hurricane on the Saffir-Simpson hurricane wind scale. After crossing Hai-Nan at peak intensity and moving into the northern portion of the Gulf of Tonkin, Vera slowly weakened before moving ashore near Haiphong at around 0000 UTC on July 18. [2] At the time of landfall, the JMA estimated winds of 105 km/h (65 mph). [3] Severe Tropical Storm Vera rapidly weakened over land [2] and by July 19, the JMA stopped monitoring Vera. [3]
Prior to the arrival of Vera, schools and government offices were shut down. Railway services were suspended; Philippine Airlines called off domestic services. [5] Upon making landfall, Vera became the first storm to hit the nation in eight months [6] while helping to relieve drought conditions. [7] Typhoon Vera killed 123 [8] and left 60 others missing across the Philippines, [9] including 100 in Luzon alone. [10] A total of 145 people were also injured. [1] Around 200,000 people were homeless. [10] The typhoon destroyed 29,054 houses [1] and "badly" damaged 5,558 others. [10] A total of 76,346 homes were "partially" damaged, which directly affected 628,985 people. [1] According to authorities, 24,280 persons sought shelter. [11] Moreover, more than 40 domestic flights were canceled due to the storm. [12]
About 80% of Manila's 7 million residents lost power due to the storm. [13] Low-lying areas of Manila were underwater as strong winds blew away roofs of shacks and uprooted trees. [5] Throughout the city, four deaths happened. [14] One man was electrocuted while another man was crushed by debris. [13] Fifty people were confirmed to have died and 2,089 dwellings were damaged in nearby Bataan after storm surge crashed into the area. [15] [16] Most of the casualties in Bataan were due to drownings; [16] the province was also the hardest hit by the storm. [17] Throughout the area near Bataan, 10 villages were destroyed. [18] In Pantalan Luma, all but four of the town's 400 huts were destroyed. [18]
About 30 houses in San Pablo, Laguna were either demolished by strong winds or by falling coconut trees. [19] Elsewhere, in Zambales, a woman was killed after she was struck by lightning. In Lucena City, a farmer was swept away via floods and two boys died due to fallen trees. [13] The resort city of Legaspi suffered severe damage because hundreds of dwellings were destroyed, forcing many residents to seek shelter in schools or churches. [5] Along the east coast of Luzon, seven people perished when hit by falling coconut trees in Quezon. Meanwhile, three casualties occurred in a fire in the province of Sorsogon. [14] A total of 15 people drowned in the town of Sexmoan. The nearby towns of Macabebe and Masantol saw two drownings each. [18] In the city of Manila or the provinces of Batangas, Quezon, Laguna, and Cavite, 34,000 people were displaced. [13] Overall, damage totaled $42 million (1983 USD). Infrastructure damage totaled $31 million. However, damage to crops totaled to only $9.4 million [1] [nb 2] since residents were just beginning to replant fields. [20]
According to the Philippine Red Cross, 26,845 families necessitated emergency assistance. [21] Government agencies were ordered to arrest profiteers, [22] hoarders and looters. [23] President Ferdinand Marcos ordered all relief agencies to submit damage reports so emergency funds can be issued. [24]
After striking Vietnam, Typhoon Vera claimed three lives [25] and damaged 2,500 houses. [26] Heavy rains helped alleviate a prolonged drought in northern Vietnam that previously prevented the planting of rice. [27] Because Typhoon Vera posed a threat to Southern China, 36 bulletins were issued by the Hong Kong Royal Observatory. A Typhoon signal No. 3 was also issued. After passing south of the area, a peak windspeed of 115 km/h (70 mph) was measured at Tate's Cairn. [28] In addition, the storm generated showers and squally weather in the region. One swimmer drowned due to rough seas. [29]
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 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 1964 Pacific typhoon season was the most active tropical cyclone season recorded globally, with a total of 39 tropical storms forming. It had no official bounds; it ran year-round in 1964, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
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 Rammasun, known in the Philippines as Super Typhoon Butchoy, was recognized as the second typhoon of the 2008 Pacific typhoon season by the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). Rammasun was also recognised as the third tropical storm, the second typhoon and the first super typhoon of the 2008 Pacific typhoon season by the Joint Typhoon Warning Center (JTWC).
Severe Tropical Storm Chanthu, known in the Philippines as Tropical Storm Gener, was a strong tropical storm that produced deadly flooding in Vietnam and Thailand. Originating from an area of low pressure on June 5, 2004, Chanthu was first declared a tropical depression near southern Leyte Island in the Philippines. Tracking west-northwestward, the depression intensified into a tropical storm over the central Philippines before entering the South China Sea. Once over the warm waters of the sea, the system quickly intensified, attaining its peak 10-minute winds of 110 km/h (70 mph) and 1-minute winds of 140 km/h (85 mph). On June 12, the storm made landfall in Vietnam before quickly weakening over land. By June 13, the system had weakened to a tropical depression and dissipated two days later.
Typhoon Dan, known in the Philippines as Typhoon Saling, was the third of a series of tropical cyclones that impacted the Philippines and Vietnam in October 1989. The storm developed on October 6, and tracked generally westward throughout its course. After crossing Luzon, the typhoon emerged into the South China Sea and reached its peak intensity, with sustained 10-minute winds of 140 km/h (85 mph), 1-minute winds of 130 km/h (80 mph), and a minimum barometric pressure of 960 millibars. The storm moved ashore in central Vietnam and dissipated after moving inland. The storm caused extensive damage throughout its course. In the Philippines, Dan left hundreds of thousands homeless and killed 58 people. Power outages were extensive in the Manila region. In Vietnam, the storm's high winds and heavy rains caused extensive damage and loss of life. More than 500,000 structures were damaged or destroyed and at least 43 people were killed across the country.
Typhoon Nelson, known in the Philippines as Typhoon Bising, was the second tropical cyclone to strike the Philippines within a week in March 1982. Nelson originated from a tropical disturbance southeast of Guam towards the middle of March. Although the system was initially poorly organized, it developed rather quickly, and was upgraded into Tropical Storm Nelson on March 19. It tracked westward, and fluctuated in intensity for several days. On March 24, Typhoon Nelson intensified into a typhoon, and entered an episode of rapid intensification. On March 25, Nelson reached its peak intensity of 115 km/h (70 mph), but thereafter moved ashore on the Philippines, where the storm weakened significantly. On March 27, the typhoon entered the South China Sea, and the next day, briefly re-intensified before resuming a weakening trend. Nelson dissipated on March 31.
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 Betty, known in the Philippines as Typhoon Herming, was a powerful and destructive tropical cyclone that struck the Philippines in August 1987. The seventh typhoon and second super typhoon of the active typhoon season, it formed from the monsoon trough that spawned a tropical cyclone on August 8 while around positioned well to the east of the Philippines. It drifted northwestward, becoming a tropical storm on August 9 and a typhoon on August 10. Betty turned westward, where it rapidly intensified before attaining peak intensity on August 11. The next day, Typhoon Betty made landfall in the central Philippines. Betty weakened rapidly over the country, but restrengthened somewhat over the South China Sea. Land interaction weakened Betty slightly before it hit central Vietnam on August 16. The next day, Betty dissipated.
Typhoon Abby, known in the Philippines as Typhoon Diding, was an extremely powerful tropical cyclone which was the second typhoon to strike Japan within a span of a few days in August 1983. First noted southeast of Guam on July 31, development of this system was initially slow to occur; it was first classified on August 5, and was upgraded into a tropical storm the next day. Intensification was rapid as Abby slowly recurved northward on August 7 and 8. After reaching peak intensity with winds of 140 mph (225 km/h) early on August 9, Abby slowly weakened, though the storm briefly re-intensified on August 11. By August 14, winds had diminished to 100 mph (160 km/h). Abby finally weakened back into a tropical storm on August 17 not long after making landfall in Japan. The following day, Abby completed the transition to an extratropical cyclone after moving through central Japan. However, meteorologists continued monitoring the storm for six more days.
Typhoon Wayne, known in the Philippines as Typhoon Katring, was an intense tropical cyclone that brought significant flooding to the Philippines in July 1983. The typhoon originated from an area of disturbed weather that formed far from land towards the end of July. Late on July 22, Wayne developed gale-force winds while moving west. The next day, it was estimated to have become a typhoon, and Wayne subsequently entered a period of rapid deepening. During the morning hours of July 24, the typhoon was estimated to have reached its peak intensity of 205 km/h (125 mph), but soon began to weaken due to interaction with land. By the time it moved ashore in southern China on July 25, Wayne had weakened considerably. After moving inland, Wayne weakened rapidly. The following day, Wayne was no longer a tropical cyclone.
Typhoon Nancy, known in the Philippines as Typhoon Weling, was a destructive typhoon that moved through Vietnam and the Philippines during October 1982. The typhoon originated from an area of convection and was first classified as a tropical cyclone on October 10. The system attained gale-force winds the next day, and slowly deepened thereafter. Although Nancy initially moved west, the system maintained a general westward course for much of its duration, striking Luzon on October 14 at peak intensity of 215 km/h (130 mph). It weakened to tropical storm strength overland, but re-intensified to typhoon intensity over the South China Sea. Nancy hit northern Vietnam on the October 18, and weakened almost immediately thereafter, before dissipating on October 20 inland over Vietnam.
Severe Tropical Storm Koni, known in the Philippines as Tropical Storm Gilas, caused moderate damage to areas of China and Vietnam in July 2003. The eighth tropical storm in the western Pacific that year, Koni originated from a disturbance situated within the monsoon trough well east of the Philippines on July 15. Tracking westward, intensification was slow and the system remained a tropical depression as it moved across the central Philippines on July 17. Upon moving into the South China Sea, however, conditions allowed for quicker strengthening, and as such the cyclone reached tropical storm status on July 18 before reaching its peak intensity with maximum sustained winds of 110 km/h (68 mph) and a minimum barometric pressure of 975 mbar, making it a severe tropical storm. However, atmospheric conditions began to deteriorate as Koni made landfall on Hainan on July 21, weakening the system. The tropical storm continued to weaken as it moved over the Gulf of Tonkin prior to a final landfall near Hanoi, Vietnam the following day. Tracking inland, the combination of land interaction and wind shear caused Koni to dissipate over Laos on July 23.
Severe 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 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 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 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 Zeke, known in the Philippines as Typhoon Etang, was the first of two typhoons to make landfall in China within a week during mid-July 1991. An area of disturbed weather developed east of the Philippines towards the end of the first week of July. Tracking west-northwestward, the disturbance organized into a tropical depression on July 9. After tracking across the Philippines, where it left two people missing and injured three others, the depression intensified into a tropical storm on July 10. The storm steadily deepened as it moved across the South China Sea, and on July 12 it strengthened into a typhoon. While at its peak intensity of 120 km/h (75 mph), Zeke moved onshore at Hainan, where it began to weaken. The system tracked across Vietnam on July 13, and dissipated within two days after moving inland.
