A severe tropical storm is the third highest category used by the Japan Meteorological Agency (JMA) to classify tropical cyclones in the Northwest Pacific basin. The basin is limited to the north of the equator between the 100th meridian east and the 180th meridian. The category of the severe tropical storm is defined as a tropical cyclone that has 10-minute sustained wind speeds of between 48 and 63 knots (89–117 km/h; 55–73 mph).
| Category | Sustained winds |
|---|---|
| Violent typhoon | ≥105 knots ≥194 km/h |
| Very strong typhoon | 85–104 knots 157–193 km/h |
| Strong typhoon | 64–84 knots 118–156 km/h |
| Severe tropical storm | 48–63 knots 89–117 km/h |
| Tropical storm | 34–47 knots 62–88 km/h |
| Tropical depression | ≤33 knots ≤61 km/h |
The Northwest Pacific basin covers a vast area in the Pacific Ocean, located north of the equator, between 100°E and 180°E. [1] Several weather agencies monitor this basin, however it is officially monitored by the Japan Meteorological Agency (JMA, RSMC Tokyo), who is responsible for forecasting, naming and issuing warnings for tropical cyclones. [1] Unofficially, the Joint Typhoon Warning Center also monitors the basin, however these warnings measures 1-minute sustained wind speeds, comparing their scale to the Saffir–Simpson scale. [2] The JMA uses a simpler scale on classifying tropical cyclones adapted by the ESCAP/WMO Typhoon Committee measuring 10-minute sustained wind speeds, ranging from a tropical depression, tropical storm, severe tropical storm and typhoon. [3]
This article covers a list of systems developing in the Northwest Pacific basin that were classified by the JMA's category of a severe tropical storm. The category of a severe tropical storm ranges with 10-minute sustained winds of 48–63 kn (25–32 m/s; 55–72 mph; 89–117 km/h). [3]

The JMA tracked a total of 42 severe tropical storms from 2000 through to 2009. Fortunately, many of these storms did not affect any landmass, however there were a few notable storms like Kammuri in 2002 and Bilis in 2006 which both impacted mainland China, killing hundreds of people and causing total combined damages of nearly US$5 billion. Bilis ended up killing a total of 859 people, making it one of the deadliest storms in China, and also, being known as the tenth wettest tropical cyclone in the country. [4]

From 2010 to 2019, the JMA tracked a total of 52 severe tropical storms. In December 2011, Severe Tropical Storm Washi impacted the southern part of the Philippines, killing a total of 2,546 people, making it one of the deadliest tropical cyclones to hit the country. [12] Mekkhala in January 2015 also affected the Philippines, but was notable for interrupting Pope Francis’ visit to the country. [13] Nine months later saw the most damaging severe tropical storm of the decade, where Etau mainly affected Japan, causing damages of up to ¥294 billion (US$2.44 billion) due to extreme flooding and various landslides. [14] Moreover, Tropical Storm Pewa moved into the Northwest Pacific basin from the Central Pacific and was classified as a severe tropical storm by the JMA. [15]

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.
Tropical Storm Mekkhala was recognised as the 16th Tropical Storm of the 2008 Pacific typhoon season by the Japan Meteorological Agency who are the Regional Specialized Meteorological Centre for the North Western Pacific Ocean. The Joint Typhoon Warning Center (JTWC) have also recognised Mekkhala as the 20th tropical depression, and the 18th tropical storm of the 2008 Pacific typhoon season.
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. The first tropical cyclone of the season formed on January 13. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the various warning agencies, such as information on a storm that was not operationally warned on, has been included.
Severe Tropical Storm Kammuri, known in the Philippines as Tropical Storm Julian, was a storm which made landfall on south China in August 2008, having a maximum wind speed of 50 kn (93 km/h). The name Kammuri was submitted to the World Meteorological Organisation's Typhoon Committee by Japan and is Japanese for the Corona Borealis constellation of stars.
The 2012 Pacific typhoon season was a slightly above average season that produced 25 named storms, fourteen typhoons, and four intense typhoons. It was a destructive and the second consecutive year to be the deadliest season. 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.
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 third costliest, behind the 2018 and 2019 seasons.
The 2014 Pacific typhoon season was a slightly below average season, featuring 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.
The 2015 Pacific typhoon season was a slightly above average season that produced twenty-seven tropical storms, eighteen typhoons, and nine super typhoons. The season ran throughout 2015, though most tropical cyclones typically develop between May and November. The season's first named storm, Mekkhala, developed on January 15, while the season's last named storm, Melor, dissipated on December 17. The season saw at least one named tropical system forming in each of every month, the first time since 1965. Similar to the previous season, this season saw a high number of super typhoons. Accumulated cyclone energy (ACE) during 2015 was extremely high, the third highest since 1970, and the 2015 ACE has been attributed in part to anthropogenic warming.
The 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was well above-average, producing twenty-nine storms, thirteen typhoons, seven super typhoons and six Category 5 tropical cyclones. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.
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.
Tropical Storm Toraji was a short-lived and minimal tropical cyclone that brought inundating rainfall to areas of Southeast Asia in July 2007. The name Toraji was contributed to the western Pacific typhoon naming list by North Korea and stands for a broad bell flower. The third named storm of the annual typhoon season, Toraji developed from an area of disturbed weather within the South China Sea on July 4. As a result of its northwesterly track, the tropical depression moved over Hainan shortly after tropical cyclogenesis. Upon its emergence into the Gulf of Tonkin on July 5, Toraji quickly intensified into a tropical storm with winds of 65 km/h (40 mph); this would be the tropical cyclone's peak intensity for its entire duration. However, the JMA indicated that tropical storm intensity had been reached a day earlier. On the evening of July 5, Toraji made its final landfall on Dongxing, Guangxi before rapidly deteriorating inland and degenerating into a remnant low-pressure area by the following day.
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.
This timeline documents all of the events of the 2014 Pacific typhoon season. 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.
Tropical Storm Lingling, known in the Philippines as Tropical Depression Agaton, was a weak but deadly tropical cyclone that affected the Philippines in January 2014. The first named storm of the annual typhoon season, this early-season cyclone remained very disorganized throughout its lifespan. Lingling was the first major natural disaster in the Philippines after Typhoon Haiyan just two months earlier, as it caused widespread landslide incidents and floods in Mindanao, resulting in 70 deaths and damage amounting to over 566 million pesos on the island.
This timeline documents all of the events of the 2012 Pacific typhoon season. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. During the season, 34 systems were designated as tropical depressions by either the Japan Meteorological Agency (JMA), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Joint Typhoon Warning Center (JTWC), or other National Meteorological and Hydrological Services such as the China Meteorological Administration and the Hong Kong Observatory. Since the JMA runs the Regional Specialized Meteorological Centre (RSMC) for the Western Pacific, they assigned names to tropical depressions which developed into tropical storms in the basin. PAGASA also assigned local names to systems which are active in their area of responsibility; however, these names are not in common use outside of the Philippines.
Severe Tropical Storm Maliksi, known in the Philippines as Severe Tropical Storm Domeng, was a tropical cyclone in June 2018 that brought rainfall to the Philippines and Japan. It caused 2 deaths and prompted the PAGASA to declare the beginning of the rainy season in the Philippines. The fifth named storm and 4th tropical cyclone in the Philippine Area of Responsibility (PAR), it was first noted as an area of convection in the South of Palau on May 31.
