Part of the 2008 Pacific typhoon season |
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).
Rammasun formed on May 5 as a tropical disturbance. The next day the Joint Typhoon Warning Center issued a tropical cyclone formation alert on the developing disturbance. On May 7 both the JTWC and the Japan Meteorological Agency designated the disturbance as a tropical depression,while PAGASA named the depression Butchoy. Later that day both the JMA and the JTWC upgraded the depression to a tropical storm with the JMA naming the storm Rammasun. On May 9 both the JTWC and the JMA upgraded Rammasun to a typhoon. The next day the JMA and the JTWC reported that Rammasun had reached its peak winds of 195 and 250 km/h (121 and 155 mph) respectively,which made Rammasun a Category 4 super typhoon on the Saffir-Simpson Hurricane Scale. After reaching its peak intensity,Rammasun weakened and was downgraded to severe tropical storm on May 12,before the JTWC declared it extratropical and issued their final advisory. The JMA did not issue their final advisory until several hours later. Within Japan an estimated 10 hectares (25 acres) of farmland were damaged. In all,the typhoon killed four people,injured 40 others and caused $9.6 million (2008 USD) worth of damage in both the Philippines and Japan.
On May 4, 2008, an area of low pressure formed in the Pacific Ocean to the southeast of Yap. The next day, the Joint Typhoon Warning Center (JTWC) upgraded the area of low pressure to a tropical disturbance and assessed the disturbances chances of forming into a significant tropical cyclone within 24 hours as poor. [1] This was because the developing low level circulation center was weak. [1] Early on May 6, the JTWC upgraded the disturbances chances of forming into a tropical cyclone within 24 hours to "fair", as the low level circulation center had consolidated further. [2] A Tropical Cyclone Formation Alert was then issued later that day, by the JTWC who upgraded the disturbance's chances of becoming a tropical cyclone by the next day as good. [3]
Early the next day both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) designated the tropical disturbance as a tropical depression with PAGASA assigning the local name of Butchoy to the depression. [4] [5] At this time the depression was located 790 km (490 mi), to the east of Mindanao in the Philippines. [5] Later that morning the JMA started to issue full advisories on the tropical depression as forecasts showed that the depression could become a tropical storm within 24 hours. [6] The JTWC then designated the depression as Tropical Depression 02W. [7] Later that day both the JTWC and the JMA reported that the depression intensified into a tropical storm, with the JMA assigning the name Rammasun to the storm. [8] [9]
Rammasun continued to intensify and was designated as a severe tropical storm late on May 8. [10] The next day both the JMA and the JTWC reported that Rammasun had intensified into a typhoon. [11] [12] Later that day the JTWC reported that the typhoon had rapidly intensified within the last six hours and had become a Category 3 typhoon on the Saffir–Simpson hurricane wind scale. [13] At the same time the JMA were reporting that Rammasun had winds of 150 km/h (93 mph). [14] The typhoon then continued to intensify quickly with the JMA reporting that Rammasun had winds of 160 km/h (99 mph), the JTWC then reported that Rammasun had become a Category 4 typhoon with winds of 225 km/h (140 mph). [15] [16] Later that day both the JMA and the JTWC reported that the typhoon had reached its peak winds. The JMA reported peak winds of 195 km/h (121 mph) whilst the JTWC reported that Rammasun had peak winds of 250 km/h (160 mph), making it a category 4 super typhoon. [17] [18] Typhoon Rammasun's minimum pressure was officially estimated at 915 hPa which tied with Intense Tropical Cyclone Hondo as second strongest storm of 2008 [18] [19]
The JTWC kept Rammasun as a super typhoon until early on May 11, when they reported that the typhoon had weakened into a category four typhoon, while the JMA were reporting that the typhoon had wind speeds of 175 km/h (109 mph). [20] [21] Later that day both agencies reported that the typhoon had weakened even further, with the JMA reporting that Rammasun had winds of 160 km/h (99 mph), while the JTWC reported that Rammasun had weakened into a Category 3 typhoon. [22] [23] The JTWC then reported within their next advisory that Rammasun had weakened into a Category 2 typhoon whilst the JMA reported that the typhoon had winds of 140 km/h (87 mph). [24] [25] The next day as the Typhoon moved out of PAGASA's area of responsibility Rammasun was downgraded to a Category 1 typhoon by the JTWC. [26] [27] Later that day the JMA downgraded Rammasun to a Severe Tropical Storm whilst the JTWC downgraded it to an extratropical cyclone and released their final advisory on the system. [28] [29] The JMA continued to issue advisories on severe tropical storm Rammasun until early the next day when they downgraded it to an extratropical low. [30]
The name "Rammasun" was one of the 10 original names submitted by Thailand to the ESCAP/WMO Typhoon Committee for use from January 1, 2000. [31] Rammasun is the Thai god for thunder. The name was last used in the 2002 Pacific typhoon season, [32] though it was retired in 2015 after Typhoon Rammasun (the same name used for the 2014 season, Typhoon Glenda in the Philippines) left considerable damages in the Philippines, China and Vietnam. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also assigned the local name of "Butchoy" to Rammasun; [5] the name "Butchoy" was last used by PAGASA to name a tropical depression in the Philippines in 2004 to name Tropical Storm 02W. [33]
Within the Philippines, PAGASA issued no public storm warning signals, as the storm was too far away from the country to prompt the issuance of such advisories. However, they did warn that the cyclone was expected to enhance the southwest monsoon and bring rain over Central and Southern Luzon, Visayas and Mindanao. [5] [26]
On May 12, a father of two drowned in rough seas produced by Rammasun after saving his children. [34] Later that day, a boat carrying 17 people capsized due to rough seas produced by the typhoon. All of the passengers were rescued the following day by the Philippine Coast Guard. [35] Heavy rains from the outer bands of Rammasun triggered flooding and mudslides in the Philippines. [36] Strong winds also downed numerous trees, one of which, measured at 60 centimetres (2.0 ft) in diameter, fell on three forest guards, killing two and critically injuring the other. [37] In Jaro, Iloilo City, a swollen river overflowed its banks, inundating the district. Local reports stated that water in the area was waist-deep in places. In Cauayan, a 15-year-old girl drowned after being washed away while crossing a bridge. Flooding in Hinoba-an, Negros Occidental destroyed six homes and damaged 24 others. An estimated 3,153 families were affected by the storm in the Philippines. [38] A strong extratropical storm from the "tail" of the former typhoon struck the Philippines after Rammasun had become extratropical. The associated winds caused severe damage to buildings, and numerous trees were uprooted. The damage may have been due to a possible tornado, although this possibility is not confirmed. At least 40 people were injured and damage totaled to PHP 61 million ($1.2 million USD). [34] [39] [40]
On May 12, the Japan Meteorological Agency issued warnings for the Tokyo area as Rammasun was forecast to make landfall near the city. [41] As Rammasun became extratropical, the storm brushed the Japanese coastline on May 13, producing winds gusting up to 85 km/h (53 mph) and high waves for several hours. [42] An estimated 10 hectares (24.7 acres) of farmland were damaged. Damage from the storm amounted to ¥770 million ($8.4 million 2008 USD) in agricultural losses. [43]
The 2008 Pacific typhoon season was a below average season which featured 22 named storms, eleven typhoons, and two super typhoons. The season had no official bounds; it ran year-round in 2008, 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.
This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation during the 2008 Pacific typhoon season. The 2008 Pacific typhoon season officially started on January 1, 2008 and ended on January 1, 2009.
Typhoon Fung-wong, known in the Philippines as Typhoon Igme, was a deadly typhoon in the 2008 Pacific typhoon season which made landfall on Taiwan and China. Typhoon Fung-wong reached peak intensity of a Category 2 typhoon on the Saffir-Simpson Hurricane Scale by the Joint Typhoon Warning Center with peak winds of 95 knots (176 km/h). Damage was extensive in Taiwan, hitting little more than a week later than Typhoon Kalmaegi, but a specific cost is unknown, though later estimated at 541 million.
Typhoon Sinlaku, known in the Philippines as Typhoon Marce, was a typhoon which affected the Philippines, Taiwan, China and Japan. It was recognised as the 13th named storm and the ninth typhoon of the 2008 Pacific typhoon season by the Japan Meteorological Agency.
Typhoon Hagupit, known in the Philippines as Typhoon Nina, was a powerful cyclone that caused widespread destruction along its path in September 2008. The 21st depression, 14 tropical storm and 10th typhoon of the 2008 Pacific typhoon season, Hagupit developed from a tropical wave located a couple hundred miles east of the Marshall Islands on September 14. Moving generally north-west westwards towards the Philippines, the depression gradually intensified into a tropical storm the following day, and then into became a typhoon on September 22 off the northern coast of Luzon. Located within an environment conducive for strengthening, Hagupit rapidly strengthened to attain 10-min sustained winds of 165 kilometres per hour and 1-min sustained winds of 230 kilometres per hour. After making landfall in Guangdong province in China at peak intensity on September 23, Hagupit rapidly weakened over rugged terrain and dissipated on the 25th.
Severe Tropical Storm Maysak, known in the Philippines as Tropical Storm Quinta-Siony, was recognised as the 19th tropical storm by the Japan Meteorological Agency. It was also recognised as the 24th tropical depression and the 22nd tropical storm by the Joint Typhoon Warning Center of the 2008 Pacific typhoon season.
The 2009 Pacific typhoon season was a below average season that spawned only 22 named storms, 13 typhoons, and five super typhoons. It was also recognized as the deadliest season in the Philippines for decades. The first half of the season was very quiet whereas the second half of the season was extremely active. The season's first named storm, Kujira, developed on May 3 while the season's last named storm, Nida, dissipated on December 3.
Typhoon Dolphin, known in the Philippines as Typhoon Ulysses, was the final named storm and typhoon of the 2008 Pacific typhoon season. The only impact that was reported from Dolphin was to the M/Bca Mae Jan, which was a cargo passenger ship which sank on December 14, due to rough seas caused by Dolphin. There were 46 people reported dead while seven were reported as missing.
Tropical Depression Auring was a weak tropical cyclone that caused floods in the Philippines in early January 2009. It formed as a tropical disturbance late on December 30, 2008, to the southeast of Manila in the Philippines, and gradually developed over the next few days. Early on January 3, 2009, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the Japan Meteorological Agency (JMA) reported that the disturbance had intensified into the first tropical depression of the season, with PAGASA assigning the name Auring to the depression. As the Depression was moving into a high level of vertical wind shear, it did not develop any further and late on January 5 as the baroclinic zone approached Auring, it was downgraded to an area of low pressure by the PAGASA before the JMA followed suit the next day as it was declared as dissipated by the JTWC.
This timeline documents all of the events of the 2009 Pacific typhoon season which was the period that tropical cyclones formed in the Western Pacific Ocean during 2009, with most of the tropical cyclones forming between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.
Typhoon Kujira, known in the Philippines as Typhoon Dante, was first reported by the Joint Typhoon Warning Center (JTWC) on April 28. It was the fourth depression and the first typhoon of the season. The disturbance dissipated later that day however it regenerated early on April 30 within the southern islands of Luzon. It was then designated as a Tropical Depression during the next morning by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the Japan Meteorological Agency (JMA), with PAGASA assigning the name Dante to the depression. However the JTWC did not designate the system as a depression until early on May 2 which was after the depression had made landfall on the Philippines. Later that day Dante was upgraded to a Tropical Storm and was named as Kujira by the JMA. The cyclone started to rapidly intensify becoming a typhoon early on May 4, and then reaching its peak winds of 155 km/h (100 mph) (10-min), 215 km/h (135 mph) (1-min) later that day after a small clear eye had developed.
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.
The 2011 Pacific typhoon season was a below average season that produced a total of 21 named storms, 8 typhoons, and four super typhoons. This season was much more active than the previous season, although both seasons were below the Pacific typhoon average of 26. The season ran throughout 2011, though most tropical cyclone tend to develop between May and October. The season's first named storm, Aere, developed on May 7 while the season's last named storm, Washi dissipated on December 19.
The 2013 Pacific typhoon season was the most active Pacific typhoon season since 2004, and the deadliest since 1975. It featured Typhoon Haiyan, one of the most powerful storms and one of the strongest landfalling tropical cyclones in history. It was an above-average season with 31 named storms, 13 typhoons, and five super typhoons. The season's first named storm, Sonamu, developed on January 4 while the season's last named storm, Podul, dissipated on November 15. Despite the activity, most of the first seventeen named storms before mid-September were relatively weak, as only two of them reached typhoon intensity. Total damage amounted to at least $26.41 billion (USD), making it at the time the costliest Pacific typhoon season on record; it is currently the fourth costliest, behind the 2018, 2019 and 2023 seasons.
The 2014 Pacific typhoon season was a slightly below average season in terms of named storms, but featured the highest amount of Category 5 typhoons since 1997. This was mainly due to a developing El Niño that favors multiple powerful storms to form in the basin. The season formed twenty-three tropical storms, eleven typhoons, eight super typhoons, and seven Category 5 typhoons. The season's peak months August and September saw minimal activity caused by an unusually strong and a persistent suppressing phase of the Madden–Julian oscillation (MJO). The season ran throughout 2014, though most tropical cyclones typically develop between May and October. The season began with the development of Tropical Storm Lingling on January 18, and ended after Tropical Storm Jangmi which dissipated on January 1 of the next year.
Typhoon Guchol, known in the Philippines as Super Typhoon Butchoy, was a powerful tropical cyclone which became the first typhoon to make landfall in Japan on June since 2004. The storm formed as tropical disturbance south-southeast of Pohnpei on June 7, and was upgraded to a tropical depression on June 10. The system later intensified in favorable conditions, and reached typhoon intensity on June 15. It reached peak intensity late on June 17, before making landfall over Japan as a typhoon on June 19. The system became extratropical shortly after traversing Japan and was last noted by the Japan Meteorological Agency on June 22.
The 2020 Pacific typhoon season was the first of an ongoing series of below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.
Most of the tropical cyclones of the 2013 Pacific typhoon season formed between May and November of that year. The scope of this article is the Pacific Ocean north of the equator, between 100°E and the International Date Line. Tropical storms which form in the Western Pacific basin are assigned a name by the Japan Meteorological Agency (JMA). Tropical depressions forming in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility, but these names are not in common use outside the Philippines.
