The 2024 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was above-average in terms of depressions and average in terms of formation of cyclonic storms. [1] Seasons have no official bounds, but cyclones tend to form between April and December, with the peak from May to Early November. These dates conventionally delimit 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. And, the depressions formed over the land, are abbreviated LAND by the Indian Meteorological Department.
The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. On average, four to five cyclonic storms form in this basin every season. [2]

After four months of inactivity, on 21 May, the India Meteorological Department (IMD) began monitoring a cyclonic circulation in the Bay of Bengal. [3] Later that day, the Joint Typhoon Warning Center (JTWC) would also begin tracking the system, noting that it was likely to become a monsoon depression. [4] The next day, the IMD noted that a low-pressure area had formed adjacent to the cyclonic circulation. [5] Late on 23 May, the IMD upgraded the system into a well-marked low, stating that it was rapidly coalescing. [6] The next day, the IMD stated that the depression formed in the Bay of Bengal, designating it as BOB 01. [7] Subsequently, the JTWC issued a Tropical Cyclone Formation Alert (TCFA), noting the depression's broad circulation center and its improving rainbands. [8] The next day, BOB 01 intensified into a deep depression. [9] The JTWC would recognize the system as a cyclone, designating it as 01B. [10] Soon after, the depression intensified into a cyclonic storm, causing the IMD to name it Remal. [11] On 26 May, Remal intensified into a severe cyclonic storm with 3-minute sustained winds of 95 km/h (60 mph). Due to favourable conditions, including high sea surface temperatures over northern Bay of Bengal and low wind shear, Remal intensified further with wind speeds reaching 110 km/h. It made landfall over Bangladesh and adjoining West Bengal on the night of 26 May. Landfall process was completed by the morning of 27 May and it had weakened into a cyclonic storm. Cyclone Remal was the most powerful cyclonic Storm of the 2024 North Indian Ocean Cyclone Season.

Peak intensity | 55 km/h (35 mph) (3-min); 995 hPa (mbar) |
On 31 July, a cyclonic circulation formed over Gangetic West Bengal. Tracking westward, on 2 August, the disturbance developed into a depression. Two days later, it intensified further, becoming a deep depression over southwest Bihar. [14] Continuing its westward track, on 5 August, the system weakened into a depression. [15] It dissipated the next day. [16]
Due to the westward shift of the monsoon trough, the depression formed on land instead of the usual formation in the Bay of Bengal. [17]
As a result of the depression, Dum Dum in Kolkata received 100 millimetres (3.9 in) of rain on 3 August. [18]

On 24 August, a cyclonic circulation formed over Madhya and Uttar Pradesh. Early the next day, on 25 August, the IMD noted that it had developed into a land depression over Rajasthan and Madhya Pradesh. [19] Later that day, the depression intensified into a deep depression southeast of Udaipur. [20] On 27 August, the JTWC began tracking the deep depression, noting that it was in a marginal environment for development. [21] Two days later, on 29 August, they issued a TCFA on the developing depression, [22] prior to designating it as Tropical Cyclone 02A early the next day. [23] Later that same day, on 30 August, the IMD upgraded it into a cyclonic storm, naming it Asna. [a] [25] [26] It further moved into the Arabian Sea. [27] On 1 September, Asna was stripped of any convection due to dry air entrainment and degenerated to a remnant low. [28]
Many parts of Gujarat and Madhya Pradesh were flooded due to heavy rains from the storm. p to 260 mm (10 in) of rain fell in Vadodara and Ahmedabad recorded 120 mm (4.7 in) of rainfall. [29] [30] Flooding in Gujarat killed 49 people. [31] [32] An initial survey reported that the Government of Gujarat suffered damages worth more than ₹250 crore (US$29 million) to government properties and public infrastructure. [33]

Late on 5 September, the IMD marked an area of low pressure in the Bay of Bengal. On 7 September, it got upgraded to a depression by the IMD and marked as Invest 92B by the JTWC. Then, on 8 September, it got upgraded to a deep depression off the coast of Odisha. On 9 September, the deep depression made landfall in Odisha and weakened back down to a prominent low pressure system. Two days later, the IMD reupgraded the system into a depression over Madhya Pradesh. On 13 September, the depression finally dissipated over northwest Uttar Pradesh.

This disturbance would coalesce into a low-pressure area the next day, [37] further developing into a well-marked low-pressure just a few hours later. [38] Soon after, it developed into a depression. [39] Early the next morning, it became a deep depression over Bangladesh and West Bengal. [40] On 15 September, it weakened back down to a depression as it slowly moved westward over western India.
Due to heavy rain from this system, seven people were killed by landslides in Cox's Bazar District. [41] Five fishermen also died [42] and over 500 more went missing in the district. [43] In Cox's Bazar, 378 mm (14.9 in) of rain was recorded within a 12-hour period from 11 to 12 September. [44] These heavy rains resulted in the flooding of over 200 villages within seven upazilas of the district. [42] Another 11 people were killed by flooding in Noakhali District, [45] where 100 fishermen went missing. Additionally, two people were killed when a boat capsized in Jagannathpur Upazila. [46] In India, heavy rains lashed Kolkata and West Bengal. 72.4 mm (2.85 in) of rain was recorded over a 24-hour period, with a total of 125.8 mm (4.95 in) was recorded in Kolkata. [47]
Due to the heavy rains, the Damodar Valley Corporation released more than 3.5 lakh cusec of water from its dams, resulting in inundation of Birbhum, Bankura, Howrah, Hooghly, North and South 24 Parganas, Purba and Paschim Medinipur, and Paschim Bardhaman districts of West Bengal. 28 people were killed due to these floods and 25,000 people had to moved to safer areas. [48]

On 14 October, a well marked low pressure area formed in the south of the Bay of Bengal. The IMD upgraded it to a depression, designating it as BOB 06, early on 15 October as it moved west-northwestwards before making landfall in Andhra Pradesh on 17 October at 04:30 IST. It weakened further into a low pressure area as it moved north-westwards into India and dissipated. [49]
In the wake of this system, heavy rains slashed Puducherry, Chennai and other parts of Andhra Pradesh, bringing these areas to a standstill. Bengaluru and its adjoining areas too received heavy rainfall. Residential neighbourhoods and roads were inundated with knee-deep water, causing widespread disruptions to daily life. The relentless downpour led to traffic congestion, crippled public transportation services, and forced the cancellation of several flights. The Southern Railway announced the cancellation and diversion of several trains due to waterlogging. [50]

A low pressure area formed in the south Bay of Bengal on October 20. On October 21, it organised into a well-marked low pressure area. It strengthened into a depression on October 22. [51] The same day in the evening, it had consolidated into a deep depression and moving in a west-northwest direction. [52] Over the next 6 hours, it intensified into cyclonic storm and was named Dana by the IMD. [b] On October 23, it further intesified into a severe cyclonic storm. [54] The system made landfall between 23:30 IST of October 24 and 08:30 IST of October 25 close to Habalikhati Nature Camp (Bhitarkanika) and Dhamra Port on the Odisha Coast, weakening into a cyclonic storm. [55] It weakened into a deep depression at a distance of 40 km north-northwest of Bhadrak [56] and then into a depression about 70 km east-southeast of Keonjhar and remained stationary over that area, weakening further into a remnant low and dissipated on October 26. [57]

On 14 November, the Bureau of Meteorology noted that a tropical low could form west of Sumatra. [58] Several days later, they noted that the tropical low was developing. [59] Further consolidation due to a westerly wind burst led to the formation of a low-pressure area over Southeast Bay of Bengal and a deadly twin cyclone on 23 November. [60] By 24 November, it intensified into a well-marked low pressure area. It intensified further into a depression on 25 November, moving northwestwards towards Tamil Nadu and Sri Lanka coast. On 26 November, it intensified further into a deep depression, later moving into Sri Lanka. On 29 November, the system strengthened into a cyclonic storm and hence was named Fengal by the IMD. [61] On 30 November, the cyclonic storm made landfall between Karaikal and Mahabalipuram close to Puducherry as a cyclonic storm. [62] [63] The next day, on 1 December, the remnants of the cyclone weakened to a deep depression and then further into a depression over the same region. [64] It weakened further into a remnant low over north interior Tamil Nadu on 2 December. [65] Subsequently, the system emerged over coastal Karnataka and proceeded into the Arabian Sea, [66] and dissipated 2 days later.

On 16 December, A low-pressure area formed over the central part of southern Bay of Bengal. On 19 December, it intensified further into a well-marked low-pressure area. On 20 December, it intensified further into a depression and moved over the west-central Bay of Bengal near Andhra Pradesh. On 21 December, it weakened into a well-marked low pressure area. [67]
Within this basin, a tropical cyclone is assigned a name when it is judged to have reached cyclonic storm intensity with winds of 65 km/h (40 mph). The names were selected by a new list from the Regional Specialized Meteorological Center in New Delhi by mid-2020. [68] There is no retirement of tropical cyclone names in this basin as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin from other basins, like the western Pacific basin, then it will retain its original name. The names used for 2024 North Indian Ocean Cyclone Season are listed below. [69]
This is a table of all storms in the 2024 North Indian Ocean cyclone season. It mentions all of the season's storms and their names, duration, peak intensities according to the IMD storm scale, damage, and death totals. Damage and death totals include the damage and deaths caused when that storm was a precursor wave or extratropical low. All of the damage figures are in 2024 USD.

The 2007 North Indian Ocean cyclone season was one of the most active North Indian Ocean cyclone seasons on record. 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 2008 North Indian cyclone season was one of the most disastrous tropical cyclone seasons in modern history, causing more than 140,000 fatalities and over US$15 billion in damage. At the time, it was the costliest season in the North Indian Ocean, until it was surpassed by 2020. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal, which is east of India, and the Arabian Sea, which is west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), however the Joint Typhoon Warning Center releases unofficial advisories for military interests. An average of four to six storms form in the North Indian Ocean every season. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.
The 2009 North Indian Ocean cyclone season was an average season in terms of the number of cyclonic storms, however the storms were mostly weak in nature. It was the first season since 2005 wherein a storm did not strength above severe cyclonic storm status. 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.
Cyclonic Storm Nisha was a fairly weak but catastrophic tropical cyclone that struck Sri Lanka, and India which killed over 200. It was the ninth tropical cyclone of the 2008 North Indian Ocean cyclone season, and the seventh tropical cyclone in the Bay of Bengal that year.
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.
Cyclonic Storm Phyan developed as a tropical disturbance to the southwest of Colombo in Sri Lanka on November 4, 2009. Over the next couple of days, the disturbance gradually developed before weakening as it made landfall on Southern India on November 7. After the disturbance emerged into the Arabian Sea, it rapidly became more of a concern to the India Meteorological Department (IMD) reporting early on November 9 that the disturbance had intensified into a Depression, and designated it as Depression ARB 03 whilst the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert. Later that day, the JTWC designated the system as Cyclone 04A. During the next day, the Depression turned towards the northeast the IMD reported that it had intensified into a Cyclonic Storm and named it as Phyan.
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 2012 North Indian Ocean cyclone season was a very inactive season. The season had a very late start, with the first system forming in October. During the season, only five systems formed, of which only two became cyclonic storms. Both the storms made landfall, and they, along with the deep depressions, were responsible for 128 deaths and economic losses worth at least $56.7 million.
The 2012 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. 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 official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. This timeline includes information that was operationally released, meaning that data from post-storm reviews by the IMD, such as a storm that was not operationally warned upon, has not been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, and dissipations during the season.
The 2013 North Indian Ocean cyclone season was an above average and deadly season. The season had no official bounds, but cyclones typically formed between May and December, with the peak from October to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
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.
The 2015 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was an average season with 4 cyclonic storms. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between months of 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.
The 2016 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was the deadliest season since 2010, killing more than 400 people. The season was an average one, seeing four named storms, with one further intensifying into a very severe cyclonic storm. The first named storm, Roanu, developed on 19 May while the season's last named storm, Vardah, dissipated on 18 December. 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 2017 North Indian Ocean cyclone season was a below average yet deadly season in the annual cycle of tropical cyclone formation. This season produced only three named storms, of which one only intensified into a very severe cyclonic storm. 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 season began with the formation Cyclone Maarutha on April 15 and ended with the dissipation of a deep depression on December 9.
The 2020 North Indian Ocean cyclone season was the costliest North Indian Ocean cyclone season on record, mostly due to the devastating Cyclone Amphan. it was an above average season featuring 5 cyclonic storms. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and November, with peaks in late April to May and October to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on May 16 with the designation of Depression BOB 01 in the Bay of Bengal, which later became Amphan. Cyclone Amphan was the strongest storm in the Bay of Bengal in 21 years and would break Nargis of 2008's record as the costliest storm in the North Indian Ocean. The season concluded with the dissipation of Cyclone Burevi on December 5. Overall, the season was slightly above average, seeing the development of five cyclonic storms.
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.
The 2023 North Indian Ocean cyclone season was an above-average and deadly season, becoming the most active since 2019, with nine depressions and six cyclonic storms forming. It was the deadliest since 2017, mostly due to Cyclone Mocha, and had the second-highest accumulated cyclone energy (ACE) in the basin, after 2019. It also had the most extremely severe cyclonic storms on record, tying 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.
Severe Cyclonic Storm Asani was a strong tropical cyclone that made landfall in India in May 2022. It was the strongest storm of 2022 North Indian Ocean cyclone season. The third depression and deep depression, and the first named storm of the 2022 North Indian Ocean cyclone season, Asani originated from a depression that the Indian Meteorological Department first monitored on May 7. Conditions rapidly favored development as the system became a deep depression by that day before intensifying to a Cyclonic Storm Asani. On the next day it further intensified and peak to a severe cyclonic storm, before making landfall as a deep depression system over Andhra Pradesh. It degenerated into a well marked low-pressure on May 12.
This timeline documents all of the events of the 2024 North Indian Ocean cyclone season. The scope of this article is limited to the North Indian basin. During the season, systems will be designated as tropical depressions by the India Meteorological Department (IMD). Since they run the Regional Specialized Meteorological Centre (RSMC) for the basin, they will assign names to tropical depressions which developed into tropical storms in the basin. The Joint Typhoon Warning Center (JTWC) also monitors the basin, issuing unofficial bulletins for tropical cyclones which form in the basin for military interests.
