The 2019 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2019, though most tropical cyclones typically develop between May and October. The season's first named storm, Pabuk, developed on January 1, becoming the earliest-forming tropical storm of the western Pacific Ocean on record, breaking the previous record held by Typhoon Alice in 1979. The season's first typhoon, Wutip, reached typhoon status on February 20. Wutip further intensified into a super typhoon on February 23, becoming the strongest February typhoon on record, [1] and the strongest tropical cyclone recorded in February in the Northern Hemisphere.

Tropical cyclone Is a rotating storm system

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean; in the south Pacific or Indian Ocean, comparable storms are referred to simply as "tropical cyclones" or "severe cyclonic storms".

Tropical cyclogenesis

Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment.

Typhoon Alice (1979)

Typhoon Alice was an unusual late/early-season Pacific typhoon that formed in late 1978 and persisted into January 1979. Typhoon Alice also caused extensive damage in the Marshall Islands, but no fatalities occurred. The storm formed on the final day of 1978 and became a tropical storm on January 1. On January 5, Alice gained typhoon status, and its first peak intensity was reached on January 8. After weakening, the storm attained a secondary peak intensity on January 11. Typhoon Alice lasted for about 15 days in the Northwestern Pacific before dissipating on January 14, 1979.

Contents

The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones which can often result in a cyclone having two names. The Japan Meteorological Agency  (JMA) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, while the Philippine Atmospheric, Geophysical and Astronomical Services Administration  (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center  (JTWC) are given a number with a "W" suffix.

100th meridian east

The meridian 100° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole.

180th meridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle

The 180th meridian or antimeridian is the meridian 180° both east and west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres. It is common to both east longitude and west longitude. It mostly passes through the open waters of the Pacific Ocean, but passes across land in Russia, Fiji and Antarctica. This meridian is used as the basis for the International Date Line, but the latter deviates from it to maintain date consistency within the territories of Russia, the United States, Kiribati, Fiji and New Zealand.

Japan Meteorological Agency meteorological service of Japan

The Japan Meteorological Agency, JMA, is an agency of the Ministry of Land, Infrastructure, Transport and Tourism. It is charged with gathering and providing results for the public in Japan, that are obtained from data based on daily scientific observation and research into natural phenomena in the fields of meteorology, hydrology, seismology and volcanology, among other related scientific fields. Its headquarters is located in Chiyoda, Tokyo.

During the year several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA and Taiwan's Central Weather Bureau. The first forecast of the year was released by PAGASA on February 7, within its seasonal climate outlook for the period January–June. [3] The outlook noted that one to two tropical cyclones were expected between January and March, while two to four were expected to develop or enter the Philippine Area of Responsibility between April and June. Moreover, PAGASA predicts an 80% chance of a weak El Niño presence during February-March-April period. [3] On May 7, the Tropical Storm Risk (TSR) issued their first forecast for the season, predicting that the 2019 season would be a slightly above average season producing 27 named storms, 17 typhoons, and ten intense typhoons. [2] One of the factors behind this is due to the possible development of a moderate El Niño anticipated within the third quarter of the year. [2]

University College London, which has operated under the official name of UCL since 2005, is a public research university located in London, United Kingdom. It is a constituent college of the federal University of London, and is the third largest university in the United Kingdom by total enrolment, and the largest by postgraduate enrolment.

PAGASA National Meteorological and Hydrological Services agency of the Republic of the Philippines

Created on December 8, 1972 by reorganizing the Weather Bureau, PAGASA now serves as one of the Scientific and Technological Services Institutes of the Department of Science and Technology.

Central Weather Bureau Chinese Weather Bureau

The Central Weather Bureau is the government meteorological research and forecasting institution of the Republic of China (Taiwan). In addition to meteorology, the Central Weather Bureau also makes astronomical observations, reports on sea conditions, and conducts research into seismology and provides earthquake reports. The Central Weather Bureau is headquartered in Taipei City and is administered under the Ministry of Transportation and Communications.

Season summary

Tropical Storm Pabuk (2019)2019 Pacific typhoon season

The season started with Tropical Storm Pabuk active to the east of Thailand, which had formed on the last day of 2018, becoming the earliest-forming tropical storm of the Western Pacific Ocean on record, breaking the previous record held by Typhoon Alice in 1979. The storm tracked westward for three days before crossing over to the North Indian Ocean. A weak tropical depression formed near the Philippines and was named Amang by PAGASA, but quickly degenerated into a remnant low. Typhoon Wutip (Betty) developed on February 18 and became the season's first super typhoon, becoming the strongest February typhoon on record. A month later, a Tropical Depression 03W formed, and was named "Chedeng" by PAGASA, which later made landfall in Mindanao and dissipated in the Sulu Sea.

Thailand Constitutional monarchy in Southeast Asia

Thailand, officially the Kingdom of Thailand and formerly known as Siam, is a country at the centre of the Southeast Asian Indochinese peninsula composed of 76 provinces. At 513,120 km2 (198,120 sq mi) and over 68 million people, Thailand is the world's 50th largest country by total area and the 21st-most-populous country. The capital and largest city is Bangkok, a special administrative area. Thailand is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the southern extremity of Myanmar. Its maritime boundaries include Vietnam in the Gulf of Thailand to the southeast, and Indonesia and India on the Andaman Sea to the southwest. Although nominally a constitutional monarchy and parliamentary democracy, the most recent coup in 2014 established a de facto military dictatorship.

Pacific Ocean Ocean between Asia and Australia in the west, the Americas in the east and Antarctica or the Southern Ocean in the south.

The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west and the Americas in the east.

1979 Pacific typhoon season typhoon season in the Pacific Ocean

The 1979 Pacific typhoon season featured the most intense tropical cyclone recorded globally, Typhoon Tip. The season also experienced above-average tropical cyclone activity. The season had no official bounds; it ran year-round in 1979, 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.

Peak intensity85 km/h (50 mph) (10-min)  996  hPa  (mbar)

A tropical disturbance formed over the southern portion of the South China Sea on December 28, 2018, [4] and it absorbed the remnants of Tropical Depression 35W (Usman) on December 30. [5] Under high vertical wind shear, the low-pressure area remained disorganized until December 31 when it was upgraded to a tropical depression by both the JMA and the JTWC. [6] As it was designated 36W by the JTWC, it was unofficially the last system of the 2018 typhoon season. [7] At around 06:00 UTC on January 1, 2019, the system was upgraded to the first tropical storm of the 2019 typhoon season and named Pabuk by the JMA, surpassing Typhoon Alice in 1979 to become the earliest-forming tropical storm of the northwest Pacific Ocean on record. [8] At that time, Pabuk was about 650 km (405 miles) southeast of Ho Chi Minh City, Vietnam and drifted westward slowly with a partially exposed low-level circulation center. [9]

South China Sea A marginal sea of the Pacific Ocean from the Karimata and Malacca Straits to the Strait of Taiwan

The South China Sea is a marginal sea that is part of the Pacific Ocean, encompassing an area from the Karimata and Malacca Straits to the Strait of Taiwan of around 3,500,000 square kilometres (1,400,000 sq mi). The sea carries tremendous strategic importance; one-third of the world's shipping passes through it, carrying over $3 trillion in trade each year, it contains lucrative fisheries, which are crucial for the food security of millions in Southeast Asia. Huge oil and gas reserves are believed to lie beneath its seabed.

Wind shear

Wind shear, sometimes referred to as wind gradient, is a difference in wind speed or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with change in altitude. Horizontal wind shear is a change in wind speed with change in lateral position for a given altitude.

2018 Pacific typhoon season Typhoon season in the Pacific Ocean

The 2018 Pacific typhoon season was an above-average season producing 29 storms, 13 typhoons, and 7 super 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 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.

Under marginal conditions including warm sea surface temperatures, excellent poleward outflow but strong vertical wind shear, Pabuk struggled to intensify further for over two days until it accelerated west-northwestward and entered the Gulf of Thailand on January 3, where vertical wind shear was slightly weaker. It became the first tropical storm over the gulf since Muifa in 2004. Moreover, it tried to form an eye revealed by microwave imagery. [10] On January 4, the Thai Meteorological Department reported that Pabuk had made landfall over Pak Phanang, Nakhon Si Thammarat at 12:45 ICT (05:45 UTC), although other agencies indicated a landfall at peak intensity between 06:00 and 12:00 UTC. [11] Pabuk became the first tropical storm to make landfall over southern Thailand since Linda in 1997. Shortly after 12:00 UTC, the JMA issued the last full advisory for Pabuk as it exited the basin into the North Indian Ocean. [12] [13]

Sea surface temperature Water temperature close to the oceans surface

Sea surface temperature (SST) is the water temperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper 30 metres (100 ft) of the ocean. SST changes diurnally, like the air above it, but to a lesser degree. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation (AMO), can effect SST's on multi-decadal time scales, a major impact results from the global thermohaline circulation, which affects average SST significantly throughout most of the world's oceans.

Outflow (meteorology) air that flows outwards from a storm system

Outflow, in meteorology, is air that flows outwards from a storm system. It is associated with ridging, or anticyclonic flow. In the low levels of the troposphere, outflow radiates from thunderstorms in the form of a wedge of rain-cooled air, which is visible as a thin rope-like cloud on weather satellite imagery or a fine line on weather radar imagery. Low-level outflow boundaries can disrupt the center of small tropical cyclones. However, outflow aloft is essential for the strengthening of a tropical cyclone. If this outflow is undercut, the tropical cyclone weakens. If two tropical cyclones are in proximity, the upper level outflow from the system to the west can limit the development of the system to the east.

Gulf of Thailand A shallow inlet in the western part of the South China Sea

The Gulf of Thailand, also known as the Gulf of Siam, is a shallow inlet in the western part of the South China Sea, a marginal body of water in the western Pacific Ocean. The gulf is around 800 km (497 mi) long and up to 560 km (348 mi) wide, has a surface area of 320,000 km2 (123,553 sq mi) and is surrounded on the north, west and southwest by Thailand, on the northeast by Cambodia and Vietnam. The South China Sea is to the southeast.

One of the islands in the south of Thailand, Koh Samui, appeared to have been spared much of the brunt of the storm with no confirmed deaths. Beaches were closed, but even with the bad weather approaching, tourists on the popular island in the Gulf of Thailand continued to visit bars and restaurants catering to them. [14]

In Vietnam, Pabuk caused one death, [15] and the losses were estimated at 27.87 billion (US$1.2 million). [16] Eight people in Thailand were killed, [17] [18] and the losses in the country were estimated to be 5 billion bahts (US$156 million. [19] Pabuk also killed one person in Malaysia. [20]

The JTWC upgraded a disturbance north of Bairiki to a tropical depression with the designation 01W late on January 4 and expected some intensification, [21] but it failed to develop and the JTWC downgraded it back to a disturbance on January 6. [22] The system continued drifting westwards for two weeks without development. On January 19, the JMA upgraded the low-pressure area to a tropical depression when it was already located about 200 km (120 mi) west of Palau. [23] Tropical Depression 01W (Amang) continued its westward motion for another day, turning northward on January 20, just off the coast of the southern Philippines. On January 21, Tropical Depression 01W abruptly turned southward, making landfall on Samar on January 22, before dissipating shortly afterward.

The tropical depression indirectly triggered landslides and flash floods in Davao Oriental and Agusan del Norte, killing 9 and leaving 1 missing. [24] [25] Agricultural losses were at PH₱216.49 million (US$4.11 million). [26]

A low pressure area formed just south of the Marshall Islands on February 16. It then began to gradually organize while moving westward, just south of Federated States of Micronesia. The system was upgraded to a tropical depression by the JMA on February 18, with the JTWC following suit on the following day. On February 20, the tropical depression intensified into a tropical storm and received the name Wutip from the JMA. On February 21, Wutip strengthened into a severe tropical storm, before intensifying further into a typhoon later that day.[ citation needed ] On February 23, Wutip intensified further, reaching its initial peak intensity as a Category 4-equivalent super typhoon with maximum 10-minute sustained winds of 185 km/h (115 mph), 1-minute sustained winds of 250 km/h (155 mph), and a minimum pressure of 925 hPa (mbar), while passing to the southwest of Guam, surpassing Typhoon Higos from 2015 as the strongest February typhoon on record. [1] Wutip underwent an eyewall replacement cycle shortly thereafter, weakening in intensity as it did so, while turning to the northwest. The typhoon finished its eyewall replacement cycle on February 24 and resumed strengthening; early on February 25, Wutip reached its peak intensity as a Category 5-equivalent super typhoon, with maximum 10-minute sustained winds of 195 km/h (120 mph), 1-minute sustained winds of 260 km/h (160 mph), and a minimum central pressure of 920 hPa (mbar). On February 26, Wutip entered a hostile environment with moderate wind shear and began to weaken, concurrently making another turn westward. On the next day, Wutip weakened into a tropical depression and lost most of its convection. On February 28, Wutip was given the name "Betty" by the PAGASA, as the storm entered the Philippine Sea. Soon afterward, Wutip entered a more hostile environment, with very high vertical wind shear (40-50 knots (45-60 mph; 75-95 km/h)) and lower sea surface temperatures, and the storm rapidly weakened until it dissipated on March 2.

Preliminary estimates of damage in Guam and Micronesia were at $3.3 million. [27] [28]

Tropical Depression 03W (Chedeng)

On March 14, Tropical Depression 03W formed over the Federated States of Micronesia. Over the next couple of days, the system drifted westward, while gradually organizing. Early on March 17, the tropical depression entered the PAGASA's area of responsibility in the Philippine Sea, and consequently, the agency assigned the name Chedeng to the storm, shortly before it made landfall on Palau. At 5:30 PST on March 19, Chedeng made landfall on Malita, Davao Occidental. [29] Chedeng rapidly weakened after making landfall in the Philippines, degenerating into a remnant low on March 19. Chedeng's remnants continued weakening while moving westward, dissipating over the southern Sulu Sea on March 20.

Infrastructural damage in Davao Region were at Php1.2 million (US$23,000). [30]

Other systems

On May 2, a low-pressure area formed over the Yap Islands. On May 7, the JMA upgraded the low-pressure area to a tropical depression. On May 8, the tropical depression dissipated, and the JMA issued their final advisory on the system. On May 10, another tropical depression formed to the east of Mindanao, and the JMA initiated advisories on the storm. Early on the next day, the tropical depression began to weaken, after encountering hostile conditions while continuing its westward track. On May 11, the tropical depression dissipated to the east of Mindanao.[ citation needed ]

On May 7, a tropical depression formed near the southwest portion of Micronesia. Over the next several days, the system slowly drifted westward, while fluctuating in intensity. On May 9, the tropical depression experienced some weakening. The weakening trend resumed on May 12, as the system drifted to the northwest. Later on the same day, the tropical depression degenerated into a remnant low. However, six hours later, on May 13, the system regenerated into a tropical depression, and the JMA re-initiated advisories on the storm. On May 15, the tropical depression degenerated into a remnant low once again. At 12:00 UTC on May 16, the storm's remnants dissipated.[ citation needed ]

Storm names

Within the Northwest Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names. [31] The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65 km/h (40 mph). [32] PAGASA names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has had an international name assigned to it. [31] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee. [32] Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in gray.

International names

A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of 65 km/h (40 mph). [33] The JMA selected the names from a list of 140 names, that had been developed by the 14 members nations and territories of the ESCAP/WMO Typhoon Committee. [34] Retired names, if any, will be announced by the WMO in 2020, though replacement names will be announced in 2021. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.

Typhoon Pabuk (2007) Pacific typhoon in 2007

Typhoon Pabuk, known in the Philippines as Tropical Storm Chedeng, was a minimal typhoon that formed during the day of August 5, 2007. The system made landfall on Taiwan on August 7, and on August 9 Pabuk passed to the south of Hong Kong.

2009 Pacific typhoon season typhoon season in the Pacific Ocean

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.

2010 Pacific typhoon season typhoon season in the Pacific Ocean

The 2010 Pacific typhoon season was the least active Pacific typhoon season on record, featuring only 14 named storms; seven of them strengthened into typhoons while one reached super typhoon intensity. The Pacific typhoon season during 2010 was in fact less active than the 2010 Atlantic hurricane season, the only such occurrence other than 2005. In the same year, the Pacific hurricane season broke the same record being the least active season on record. During the season no storms have made landfall in mainland Japan, the only second such occurrence since 1988. Also, all of the 14 named storms developed west of 150°E. Moreover, the season had an index total Accumulated Cyclone Energy (ACE) of 115, which is the second lowest in the basin after 1999. It was also the fourth consecutive year with a below average ACE index.

Timeline of the 2009 Pacific typhoon season

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.

2011 Pacific typhoon season typhoon season in the Pacific Ocean

The 2011 Pacific typhoon season was a slightly 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.

2013 Pacific typhoon season typhoon season in the Pacific Ocean

The 2013 Pacific typhoon season was the most active Pacific typhoon season since 2004, as well as the deadliest since 1975. 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. Most of the first seventeen named storms before mid-September were relatively weak, as only two of them reached the typhoon strength.

2014 Pacific typhoon season typhoon season in the Pacific Ocean

The 2014 Pacific typhoon season was a slightly below average season, featuring 23 tropical storms, 11 typhoons, and 8 super 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.

2015 Pacific typhoon season typhoon season in the Pacific Ocean

The 2015 Pacific typhoon season was a slightly above average season that produced 27 tropical storms, 18 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 second highest since the 1970, and the 2015 ACE has been attributed in part to anthropogenic warming.

2017 Pacific typhoon season typhoon season in the Pacific Ocean

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 and latest 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.

Tropical Storm Pabuk (2019) Weak storm that struck the southern tip of Thailand in January 2019

Tropical Storm Pabuk, also referred to as Cyclonic Storm Pabuk, was a weak storm that struck the Malay Peninsula in January 2019. It was also the earliest-forming storm in both the Northwestern Pacific Ocean and North Indian Ocean basins on record. Forming on the last day of 2018, Pabuk persisted into 2019, spanning two calendar years, and crossed into the North Indian Ocean basin several days later. The first tropical cyclone and named storm of the 2019 Pacific typhoon and North Indian Ocean cyclone seasons, Pabuk originated as a tropical disturbance in the South China Sea on December 28, 2018, which organized into a tropical depression on December 31. A day later, on January 1, 2019, the system intensified into a tropical storm and was named Pabuk. Pabuk made landfall in Thailand on January 4, emerging into the Bay of Bengal in the North Indian Ocean basin shortly afterward. Pabuk weakened after it entered the North Indian Ocean, eventually degenerating into a remnant low on January 7, before dissipating on the next day.
