This timeline documents all of the events of the 2005 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean during 2005. Most of these tropical cyclones formed between May and November 2005. 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 (JMA). Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). 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.
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.
The 2012 Pacific typhoon season was a slightly above average but destructive and second consecutive year to be the deadliest season. Though rather active since 2004. It produced 25 named storms, fourteen typhoons, and four intense 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 2012, though most tropical cyclones typically develop between May and October. The season's first named storm, Pakhar, developed on March 28, while the season's last named storm, Wukong, dissipated on December 29. The season's first typhoon, Guchol, reached typhoon status on June 15, and became the first super typhoon of the year on June 17.
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 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.
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 2014 Pacific typhoon season was a slightly below average season, featuring 23 tropical storms, 11 typhoons, 8 super typhoons, and 7 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.
The 2017 Pacific typhoon season was a below-average season in terms of accumulated cyclone energy and the number of typhoons and super typhoons, and the first since the 1977 season to not produce a Category 5-equivalent typhoon on the Saffir–Simpson scale. The season produced a total of 27 named storms, 11 typhoons, and only two super typhoons, making it an average season in terms of storm numbers. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25, while the season's last named storm, Tembin, dissipated on December 26. This season also featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.
The 2020 Pacific typhoon season was the first with below-average tropical cyclone activity since 2017, 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 fifth-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.
Severe Tropical Storm Rumbia, known in the Philippines as Tropical Storm Gorio, was a tropical cyclone that brought widespread flooding in areas of the Philippines and China late June and early July 2013. The sixth internationally named storm of the season, Rumbia formed from a broad area of low pressure situated in the southern Philippine Sea on June 27. Steadily organizing, the initial tropical depression moved towards the northwest as the result of a nearby subtropical ridge. On June 28, the disturbance strengthened to tropical storm strength, and subsequently made its first landfall on Eastern Samar in the Philippines early the following day. Rumbia spent roughly a day moving across the archipelago before emerging into the South China Sea. Over open waters, Rumbia resumed strengthening, and reached its peak intensity with winds of 95 km/h (50 mph) on July 1, ranking it as a severe tropical storm. The tropical cyclone weakened slightly before moving ashore the Leizhou Peninsula late that day. Due to land interaction, Rumbia quickly weakened into a low pressure area on July 2 and eventually dissipated soon afterwards.
This timeline documents all of the events of the 2012 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean during 2012. Most of these tropical cyclones formed between May and November 2012. 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 (JMA). Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). 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 Hagupit, known in the Philippines as Super Typhoon Ruby, was the second most intense tropical cyclone in 2014. Hagupit particularly impacted the Philippines in early December while gradually weakening, killing 18 people and causing $114 million of damage in the country. Prior to making landfall, Hagupit was considered the worst threat to the Philippines in 2014, but it was significantly smaller than 2013's Typhoon Haiyan.
This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones formed 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. This area, called the Western Pacific basin, is the responsibility of the Japanese Meteorological Agency (JMA). They host and operate the Regional Specialized Meteorological Center (RSMC), located in Tokyo. The Japanese Meteorological Agency (JMA) is also responsible for assigning names to all tropical storms that are formed within the basin. However, any storm that enters or forms in the Philippine Area of Responsibility (PAR) will be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) using a local name. Also of note - the Western Pacific basin is monitored by the United States' Joint Typhoon Warning Center (JTWC), which gives all Tropical depressions a number with a "W" suffix.
Typhoon Tembin, known in the Philippines as Typhoon Vinta, was the deadliest tropical cyclone to strike Mindanao since Typhoon Bopha in 2012. Following and impacting the Philippines less than a few days after the deadly Tropical Storm Kai-tak, Tembin, which means Libra in Japanese, the twenty-seventh named storm and the eleventh typhoon of the 2017 Pacific typhoon season. It was first classified as a weak tropical depression on December 16. The system gradually intensified and consolidated into a tropical storm on December 20. Tembin made landfall in Mindanao late the next day. On December 23, Tembin followed a path towards the South China Sea and intensified into a typhoon early the following day. Quick intensification ensued and Tembin reached its peak intensity as a low-end Category 2 typhoon as assessed by the Joint Typhoon Warning Center on December 24. Unfavorable conditions enhanced by the winter monsoon caused Tembin to rapidly weaken shortly afterwards, before it ultimately dissipated on December 26 while just south of Vietnam.
The 2021 Pacific typhoon season was the second consecutive to have below-average tropical cyclone activity, with twenty-two named storms, and was the least active since 2011. Nine became typhoons, and five of those intensified into super typhoons. This low activity was caused by a strong La Niña that had persisted from the previous year. The season's first named storm, Dujuan, developed on February 16, while the last named storm, Rai, dissipated on December 21. The season's first typhoon, Surigae, reached typhoon status on April 16. It became the first super typhoon of the year on the next day, also becoming the strongest tropical cyclone in 2021. Surigae was also the most powerful tropical cyclone on record in the Northern Hemisphere for the month of April. Typhoons In-fa and Rai are responsible for more than half of the total damage this season, adding up to a combined total of $2.02 billion.
The 2022 Pacific typhoon season was the third consecutive season to have below-average tropical cyclone activity, with twenty-five named storms, of which ten became typhoons, and three intensified into super typhoons. The season saw a slightly below average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.
Tropical Depression Usman was a weak but deadly tropical cyclone that impacted the southern Philippines in December 2018. Tropical Depression Usman originated first as a low-pressure area to the east of Palau on December 23. Slowly intensifying, the system became a tropical depression two days later. The system maintained its intensity while moving in a general west-northwestward direction approaching the eastern portion of the Philippine islands. However, due to unfavorable conditions, the depression weakened into a remnant low on December 29, while making landfall over Eastern Samar thereafter.
Tropical Storm Krovanh, known in the Philippines as Tropical Depression Vicky, was a tropical cyclone which caused deadly flooding in the Philippines during December 2020. The 31st depression and 23rd and final named storm of the 2020 Pacific typhoon season, Krovanh originated from a tropical depression which was first monitored by PAGASA, late on December 17. The system strengthened with PAGASA naming it Vicky, meanwhile the JMA monitored it as a low pressure area. The depression then made several landfalls over the Philippines on December 18–19 before moving out of the PAR on December 20, as it strengthened into a tropical storm according to the JMA and was named Krovanh. However, Krovanh was downgraded back to a tropical depression the next day, with the JTWC issuing their final advisory on December 22.
Severe Tropical Storm Nalgae, known in the Philippines as Severe Tropical Storm Paeng, was a very large and deadly tropical cyclone that wreaked havoc across the Philippines and later impacted Hong Kong and Macau. Nalgae, meaning wing in Korean, the twenty-second named storm of the 2022 Pacific typhoon season, Nalgae originated from an invest located east of the Philippines on October 26. The disturbance, initially designated as 93W, was eventually upgraded the following day to a tropical depression by the Joint Typhoon Warning Center (JTWC) and re-designated as 26W. The Japan Meteorological Agency (JMA) however, had already considered the disturbance as a tropical depression a day prior to JTWC's; the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also followed the JMA's lead and gave it the name Paeng. That same day, it was upgraded again by the JMA to tropical storm status, thus gaining the name Nalgae. The next day, the PAGASA and the JTWC upgraded Nalgae to a severe tropical storm status on October 28. Nalgae would eventually made its first landfall in Virac, Catanduanes, which was quickly followed by another landfall thirty minutes later. It then traversed the Bicol Region and emerged into Ragay Gulf, eventually making another landfall. Defying initial forecasts, Nalgae then moved southwestward and struck Mogpog. Afterwards, the storm moved northwestward into the Sibuyan Sea and struck Sariaya. Then it would move through many regions throughout the evening of October 29. Nalgae emerged over the West Philippine Sea the next day and weakened below tropical storm status. The storm would later re-intensify into a severe tropical storm a few hours later, and eventually exited the Philippine Area of Responsibility a day later. Upon its exit from Philippine jurisdiction, Nalgae then intensified into a Category 1-equivalent typhoon on JTWC; however, the JMA maintained its severe tropical storm classification for the system. It then approached the Pearl River Delta. At around 04:50 CST on November 3, 2022, Nalgae made its final landfall at Xiangzhou District as a tropical depression.
