The 2008 North Indian Ocean cyclone season officially ran throughout the year during 2008, with the first depression forming on April 27. The timeline includes information that was not operationally released, meaning that information from post-storm reviews by the Joint Typhoon Warning Center (JTWC), and the India Meteorological Department (IMD), such as information on a storm that was not operationally warned on. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation's during the 2008 North Indian Ocean cyclone season.
The 1994 North Indian Ocean cyclone season was a below-average year in which eight tropical cyclones affected seven countries bordering the North Indian Ocean. The India Meteorological Department tracks all tropical cyclones in the basin, north of the equator. The first system developed on March 21 in the Bay of Bengal, the first March storm in the basin since 1938. The second storm was the most powerful cyclone of the season, attaining maximum sustained winds of 215 km/h (135 mph) in the northern Bay of Bengal. Making landfall near the border of Bangladesh and Myanmar, the cyclone killed 350 people and left US$125 million in damage.
The 2010 North Indian Ocean cyclone season was one of the most active tropical cyclone season in the North Indian Ocean since 1998. The season saw 8 depressions and 5 named storms forming in the region.
The 2011 North Indian Ocean cyclone season was the least active tropical cyclone season in the North Indian Ocean since 1993. Only two cyclonic storms formed, below the average of four to six. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.
The 2014 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. The season included two very severe cyclonic storms, both in October, and one other named cyclonic storm, classified according to the tropical cyclone intensity scale of the India Meteorological Department. Cyclone Hudhud is estimated to have caused US$3.58 billion in damage across eastern India, and more than 120 deaths.
Typhoon Lingling, known in the Philippines as Typhoon Nanang, was a deadly typhoon that struck the Philippines and Vietnam in 2001 and caused 379 deaths. The name "Lingling" was given by Hong Kong. The 39th tropical depression, 22nd named storm, and 13th typhoon of the 2001 Pacific typhoon season, Lingling developed into a tropical depression on November 6 and given the local name Nanang by the PAGASA. The next day, it was upgraded into a tropical storm and given the name Lingling by the Japan Meteorological Agency (JMA). Lingling's intensity briefly stagnated as it moved over Visayas before resuming intensification and intensifying into a severe tropical storm on November 8. One day later, both the JMA and the Joint Typhoon Warning Center (JTWC) upgraded Lingling to a typhoon as it exited the Philippine archipelago and moved into the South China Sea. After intensifying into a typhoon, Lingling began to quickly intensify, peaking with 10-min sustained winds of 155 km/h (96 mph) and 1-min sustained winds of 215 km/h (134 mph), with a minimum central pressure of 940 mbar (28 inHg). Lingling began to weaken as it approached the Vietnamese coast, before making landfall on November 11 at 18:00 UTC. Lingling rapidly weakened afterward, dissipating on November 12.
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.
This timeline documents all of the events of the 2016 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.
The 2018 North Indian Ocean cyclone season was one of the most active North Indian Ocean cyclone seasons since 1992, with the formation of fourteen depressions and seven cyclones. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The 2015 North Indian Ocean cyclone season was a below-average tropical cyclone season which featured the highest number of deaths since the 2010 season. Despite inactivity in the Bay of Bengal caused by the ongoing El Niño, the season produced an above-average number of tropical cyclones in the Arabian Sea. The first storm of the season, Ashobaa, formed on 7 June, while the final storm of the season, Megh, ultimately dissipated on 10 November.
The 2018 Pacific typhoon season was formerly the costliest Pacific typhoon season on record before being surpassed the following year. The season had no official boundaries, and storms can form year-round, as evidenced by the formation of Tropical Storm Bolaven in late December 2017, and Tropical Storm Pabuk on December 31, 2018. Despite this, activity usually peaks between May and November. The season featured above-average activity, with 29 named storms, 13 typhoons, and 7 super typhoons forming in the West Pacific.
Extremely Severe Cyclonic Storm Mekunu was the strongest storm to strike Oman's Dhofar Governorate since 1959. The second named storm of the 2018 North Indian Ocean cyclone season, Mekunu developed out of a low-pressure area on May 21. It gradually intensified, passing east of Socotra on May 23 as a very intense tropical cyclone. On May 25, Mekunu reached its peak intensity. The India Meteorological Department estimated 10 minute sustained winds of 175 km/h (110 mph), making Mekunu an extremely severe cyclonic storm. The American-based Joint Typhoon Warning Center estimated slightly higher 1 minute winds of 185 km/h (115 mph). While at peak intensity, Mekunu made landfall near Raysut, Oman, on May 25. The storm rapidly weakened over land, dissipating on May 27.
The 2021 North Indian Ocean cyclone season was an average season, the North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, peaking between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on April 2, when a depression designated as BOB 01 was formed in the north Andaman Sea and quickly made landfall in Myanmar. The basin remained quiet for over a month before Cyclone Tauktae formed. It rapidly intensified into an extremely severe cyclonic storm before making landfall in Gujarat, become the strongest storm ever to strike that state since the 1998 Gujarat cyclone. Later that month, BOB 02 formed and later strengthened into Cyclone Yaas. Yaas rapidly intensified into a very severe cyclonic storm before making landfall in northwestern Odisha. The season's strongest tropical cyclone was Cyclone Tauktae, with maximum wind speeds of 185 km/h (115 mph) and a minimum barometric pressure of 950 hPa (28.05 inHg).
The 2022 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was an above-average season in terms of depressions and average in terms of deep depressions, but slightly below average in terms of cyclonic storms. It was also the least deadly North Indian Ocean cyclone season since 1988, according to official data. The season's strongest tropical cyclone was Cyclone Asani, with maximum wind speeds of 100 km/h and a minimum barometric pressure of 982 hPa. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the peak from May to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
Very Severe Cyclonic Storm Luban was the third tropical cyclone to affect the Arabian Peninsula during the 2018 North Indian Ocean cyclone season, after cyclones Sagar and Mekunu in May. Luban developed on October 6 in the central Arabian Sea, and for much of its duration, maintained a general west-northwestward trajectory. On October 10, the India Meteorological Department (IMD) upgraded Luban to a very severe cyclonic storm – equivalent to a Category 1 hurricane – and estimated maximum sustained winds of 140 km/h (85 mph). The storm made landfall on October 14 in eastern Yemen, as a cyclonic storm. The storm quickly weakened over the dry, mountainous terrain of the Arabian Peninsula, before dissipating on October 15.
Cyclone Gaja was the sixth named cyclone of the 2018 North Indian Ocean cyclone season, after Cyclones Sagar, Mekunu, Daye, Luban, and Titli. Forming on November 5 as a low-pressure system over the Gulf of Thailand, the system crossed through Southern Thailand and the Malay Peninsula and eventually crossed into the Andaman Sea. The weak system intensified into a depression over the Bay of Bengal on November 10 and further intensified to a cyclonic storm on November 11, being named Gaja. After tracking west-southwestward for a number of days in the Bay of Bengal, Gaja made landfall in South India on November 16, moved westward through Vedaranyam, Thiruthuraipoondi, Mannargudi, Muthupet, Pudukkottai, Adirampattinam, Pattukkottai, and Peravurani. The storm survived its crossing into the Arabian Sea; however, it degenerated into a remnant low in hostile conditions only a few days later, before dissipating early on November 22. 45 people were killed by the storm. 8 people were killed in the town of Pattukottai alone. Gaja had severe impacts in South India, particularly in Tamil Nadu. After Cyclone Gaja, Tamil Nadu sought Rs 15,000 crore from Indian central government to rebuild.
Very Severe Cyclonic Storm Titli was a deadly and destructive tropical cyclone that caused extensive damage to Eastern India in October 2018. Titli was the twelfth depression and fifth named storm to form in the 2018 North Indian Ocean cyclone season. Titli originated from a low pressure area in the Andaman Sea on October 7. With warm sea surface temperatures and low wind shear, the low developed into a depression on October 8 in the central Bay of Bengal. It was tracked and followed by the India Meteorological Department (IMD), which also issued warnings and notices for the public. Titli continued to intensify at it moved toward the southeast Indian coast, becoming a very severe cyclonic storm, equivalent to a minimal hurricane on the Saffir–Simpson scale. It attained the intensity at the same time Cyclone Luban in the Arabian Sea was at the same intensity, marking the first instance since 1977 of simultaneous storms. The IMD estimated peak winds of 150 km/h (95 mph), while the American-based Joint Typhoon Warning Center (JTWC) estimated peak winds of 195 km/h (120 mph). Late on October 10, Titli made landfall in Andhra Pradesh, and it quickly weakened over land as it turned to the northeast. It degenerated into a remnant low on October 12.
The 2013 North Indian Ocean cyclone season was an average season during the period of tropical cyclone formation in the North Indian Ocean. The season began in May with the formation of Cyclone Viyaru, which made landfall on Bangladesh, destroying more than 26,500 houses. After a period of inactivity, Cyclone Phailin formed in October, and became an extremely severe cyclonic storm. Additionally, it was a Category 5-equivalent cyclone on the Saffir–Simpson hurricane wind scale. It then made landfall in the Indian states of Andhra Pradesh and Odisha, becoming the most intense cyclone to strike the country since the 1999 Odisha cyclone. In November, cyclones Helen and Lehar formed, and they both made landfall in Andhra Pradesh just one week away from each other. The latter also affected the Andaman and Nicobar Islands.
Severe Cyclonic Storm Phethai was a tropical cyclone which affected some portions of Sri Lanka and India during December 2018. The fourteenth depression, ninth deep depression, seventh cyclonic storm, and fifth severe cyclonic storm of the 2018 North Indian Ocean cyclone season, Phethai developed from an area of low pressure that formed over the Bay of Bengal on December 13. Having forecasted not to develop significantly, the depression then strengthened to a deep depression later that day before becoming a cyclonic storm on December 15. Phethai further intensified and peaked to a severe cyclonic storm, the following day. The system then steadily weakened due to land interaction and increasing wind shear, before making landfall as a disorganized system over Andhra Pradesh on December 17. It degenerated to an area of low-pressure inland later that day.
The 2023 North Indian Ocean cyclone season was an above-average and deadly season, becoming the deadliest season since 2017, mainly due to Cyclone Mocha. With nine depressions and six cyclonic storms forming, it became the most active season, featuring the second-highest accumulated cyclone energy (ACE) on record only behind 2019. It also had the most extremely severe cyclonic storms on record, tieing with 1999 and 2019. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the peak from May to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. However, a cyclone can form at any time during the year shown by an unnamed depression that affected Sri Lanka in January-February.
