In late July 2020, an area of atmospheric convection began to persist approximately 410 km (255 mi) east of Virac, Catanduanes. [1] Afterwards, the Joint Typhoon Warning Center (JTWC) designated the system a low-chance of developing into a tropical cyclone. [2] Although situated within an environment generally conducive for the formation of a tropical cyclone, [2] the low-pressure area moved towards Luzon, emerging in the South China Sea with little to no organization. [3] [4] The low-pressure system then later left the Philippine Area of Responsibility and moved towards the South China Sea. [5] By the following hours, the JTWC upgraded the disturbance's chance to develop at medium, assessing that the disturbance is a monsoon depression. [2]

On the following day, July 31, the Japan Meteorological Agency (JMA) designated the invest as a tropical depression. [6] In a favorable environment of low vertical shear, excellent equatorial outflow and 31 °C sea surface temperatures, [2] the depression continued to organize, and by the next day, the JMA upgraded depression to a tropical storm, naming it Sinlaku. [7] The JTWC would later follow suit, upgrading the monsoon depression to tropical storm status. [8] Sinlaku would later not intensify further, although the JMA said the storm's pressure lowered to 992 hPa (29.29 inHg). [9] The storm would later make landfall on northern Vietnam, [10] and both agencies issued final advisories on Sinlaku. [11] [12]

Preparations and impact

Philippines

As a low-pressure area, Sinlaku dumped heavy rain associated with the southwest monsoon over regions of Luzon and Visayas. [4] After crossing Luzon, the storm exited the Philippine Area of Responsibility but it intensified the monsoon. [5]

Vietnam

In preparation for the storm, Nghệ An Province authorities recalled over 3,000 vessels carrying over 15,000 sailors to shore. Vietnam prime minister Nguyễn Xuân Phúc urged relevant ministries and agencies "to remain updated on the developments of the storm, and map out scenarios for the possible risks of flashfloods, landsides, and severe flooding." [13]

Nearing the northern coast, Sinlaku caused heavy rains across the area, damaging more than 4,000 hectares of crops and over 9,000 hectares of rice crops. The storm damaged over 1,400 houses, with 32 houses being flooded with 30-40 centimeters. Two people were dead, 1 in both Hoa Binh and Quang Ninh provinces, and two were injured in the province of Lam Dong. A thunderstorm from the storm broke 29 trees in districts of Hanoi. [14] The Copernicus emergency satellite mapping service was activated on 3 August to support the damage assessment across northern Vietnam. [15] Total damages were about 300 billion đồng (US$12.94 million). [16]

Thailand

Moving towards Thailand, Sinlaku's heavy rains caused flash flooding which two people were killed. [15] In Loei Province, the storm brought heavy rains and flash flooding, submerging around 550 households and damaging farmland in the province. In total, 1,399 households were affected by the flash floods. [17]

Laos

In Xayaboury Province, more than 1,000 people were affected and over 200 houses were damaged. [15]

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.

<span class="mw-page-title-main">2013 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

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.

Typhoon Kai-tak, known in the Philippines as Tropical Storm Helen, was a mild tropical cyclone that affected China, Vietnam and Laos. It was the seventh typhoon and the thirteenth named storm of the 2012 Pacific typhoon season. The storm killed 41 people and caused a sum of US$765 million in losses. Kai-tak can be tracked back to the broad area of disturbance embedded in a monsoonal trough that was first spotted, early on August 10. It was only at midnight, on August 16, when the JMA officially declared Kai-tak a typhoon. On the morning of August 17, the windspeed dropped to 60 knots and was no longer a typhoon. The typhoon caused heavy damage in China's two provinces killing four people and causing huge economic loss. Kai-Tak slammed the northern Philippines triggering flash floods and landslides and killing at least ten people, one week after deadly monsoon rains battered the country. In Vietnam, Kai-Tak has stormed across the country's north bringing high winds and floods to several areas including the capital Hanoi.

<span class="mw-page-title-main">2020 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

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.

<span class="mw-page-title-main">Timeline of the 2012 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">2021 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

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.

<span class="mw-page-title-main">2022 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

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 Storm Linfa was a weak, short-lived but deadly and destructive tropical cyclone that was the twelfth wettest tropical cyclone on record and the second of nine tropical cyclones in a row to strike Vietnam in 2020, a little under a month after the less damaging Tropical Storm Noul. The fifteenth named storm of the 2020 Pacific typhoon season, Linfa originated from a tropical depression which formed just to the west of the Philippines on October 6. After passing through the island nation, the storm emerged into the South China Sea and slowly gained strength, earning the name Linfa on October 10 on approach to Vietnam. On the next day, Linfa had reached peak strength and made landfall in Vietnam, marking the beginning of a devastating series of floods in the country and worsening the already active monsoon season. Linfa quickly dissipated as it moved inland, but associated thunderstorms continued for several days.

<span class="mw-page-title-main">Tropical Storm Koguma</span> Pacific tropical storm in 2021

Tropical Storm Koguma was a weak tropical cyclone that made landfall in Vietnam, causing minor damage. The fourth named storm of the 2021 Pacific typhoon season, the system was first noted as an area of persistent convection on the South China Sea on June 10, with the JTWC assessing the system in its first advisory as a monsoon depression. Tracking west-northwestward, marginally conductive environmental conditions in the area allowed slight intensification while drifting towards Hainan Island. On the next day, the JMA upgraded the system to a tropical depression as it passed to the south of the territory before the agency upgraded the system to a tropical storm on June 12, being assigned the name Koguma. The JTWC; however still treated the system as a tropical depression until 12:00 UTC that day. It continued to move northwest over the warm waters of the Gulf of Tonkin, eventually making landfall in Vietnam over Thanh Hóa by the end of the same day, rapidly weakening afterward.

<span class="mw-page-title-main">Tropical Storm Kompasu (2021)</span> Pacific tropical storm in 2021

Severe Tropical Storm Kompasu, known in the Philippines as Severe Tropical Storm Maring was a very large and deadly tropical cyclone that affected the Philippines, Taiwan, and southeast China. Part of the 2021 Pacific typhoon season, Kompasu originated from an area of low pressure east of the Philippines on 6 October 2021. The Japan Meteorological Agency (JMA) classified it as a tropical depression that day. A day later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) classified it as a tropical depression, naming it Maring. The cyclone was initially heavily disorganised, competing with another vortex, Tropical Depression Nando. Eventually, Maring became dominant, and the JMA reclassified it as a tropical storm, naming it Kompasu. Kompasu made landfall in Cagayan, Philippines, on 11 October 2021, and two days later, the storm made landfall in Hainan, China. The cyclone dissipated on 14 October 2021 while located over Vietnam.

Severe Tropical Storm Talim, known in the Philippines as Tropical Storm Dodong, was a compact tropical cyclone that affected the Philippines, China, and Vietnam. The fourth named storm of the 2023 Pacific typhoon season, Talim originated from a weak monsoon depression east of Manila while moving towards Luzon. The system continued to track westward close to the northern edge of mainland Luzon before emerging off the coast of Ilocos Norte. A favorable environment allowed the fledgling tropical storm to rapidly intensify to a Category 2-equivalent typhoon on the Saffir–Simpson scale. The storm maintained this intensity until shortly before landfall near Zhanjiang, Guangdong on July 17. Talim quickly weakened and dissipated early on July 18.
