Part of the 2019 North Indian Ocean cyclone season |
Super Cyclonic Storm Kyarr [nb 1] was an extremely powerful tropical cyclone that became the first super cyclonic storm in the North Indian Ocean since Gonu in 2007. It was also the second strongest tropical cyclone in the Arabian Sea and one of the most intense tropical cyclones in North Indian Ocean history. [1] The seventh depression,fifth named cyclone,and the first,and only Super Cyclonic Storm of the annual season,Kyarr developed from a low-pressure system near the Equator. The system organized itself and intensified to a tropical storm on October 24 2019 as it moved eastwards. The storm underwent rapid intensification and reached Super Cyclonic Storm status on October 27,as it turned westward. On that same day,Kyarr peaked as a Super Cyclonic Storm,with maximum 3-minute sustained winds of 240 km/h (150 mph),maximum 1-minute sustained winds of 250 km/h (155 mph),and a minimum central pressure of 922 millibars (27.2 inHg),making the system a high-end Category 4-equivalent tropical cyclone. Afterward,Kyarr gradually began to weaken,while curving westward,and then turning to the southwest. On October 31,Kyarr weakened into a Deep Depression,before turning southward on November 2,passing just to the west of Socotra. Kyarr degenerated into a remnant low later that day,before dissipating on November 3,just off the coast of Somalia.
Despite the immense strength of the storm,and many countries being affected by high tides and storm surges,there were no reported fatalities in Socotra,though there were 5 people reported dead in Karnataka,India,due to heavy rains. [2]
A low-pressure area formed on October 17 in the Arabian Sea west of India near the Lakshadweep islands. Around that time, the India Meteorological Department (IMD) anticipated that the low would eventually develop into a tropical cyclone. The low remained in the same general region for a few days, becoming well-marked by October 22. The IMD classified the system as a Depression early on October 24, upgrading it to a Deep Depression later that day. [3] On the same day, the Joint Typhoon Warning Center (JTWC) began issuing warnings on the system, classifying it as Tropical Cyclone 04A.
The Deep Depression initially moved to the northeast, towards the west coast of India. Early on October 25, the IMD upgraded the system to a Cyclonic Storm, naming it Kyarr. Later that day, the storm turned northward and intensified further into a Severe Cyclonic Storm. [3] Warm water temperatures of around 28 °C (82 °F), as well as low wind shear, fueled rapid intensification. [4] Kyarr turned to the northwest, away from India, on October 26. On the same day, the IMD upgraded the storm to a Very Severe Cyclonic Storm, and later, to an Extremely Severe Cyclonic Storm. Early on October 27, the IMD upgraded Kyarr further to a Super Cyclonic Storm, the first one in the Arabian Sea since Gonu in 2007; it was also the only recorded Super Cyclonic Storm in the Arabian Sea to occur after the monsoon season. [3] The IMD estimated the peak maximum sustained winds of 240 km/h (150 mph), with a minimum central pressure of 922 mbar (27.2 inHg) estimated by the IMD. [3] [5] The JTWC estimated slightly higher winds of 250 km/h (155 mph). [4]
At its peak, Kyarr had a well-defined eye, surrounded by well-defined rainbands and outflow. [6] For about 12 hours, Kyarr maintained peak intensity, although it remained a super cyclonic storm for about 51 hours while moving toward the Arabian Peninsula. On October 30, the storm began weakening as the track shifted to the west, falling to the intensity of a Severe Cyclonic Storm. On the same day, Kyarr co-existed with Extremely Severe Cyclonic Storm Maha, marking the first time on record that there were two simultaneous Cyclonic Storms in the Arabian Sea. Kyarr turned to the southwest, paralleling the coastline of the Arabian Peninsula offshore. On October 31, Kyarr weakened to a Deep Depression, and Kyarr deteriorated further into a Depression on the next day. The storm's circulation passed just north of Socotra on November 2. Shortly afterward, the system weakened into a remnant low off the northern coast of Somalia, before dissipating on the next day. [3]
Due to the large circulation of the cyclone, the IMD recommended all fishermen avoid sailing in the Arabian Sea for five days. The Indian Coast Guard rescued at least 19 fishermen caught by the storm. [7] The Indian Navy rescued 17 fishermen from a boat that sank amid high seas west of Mumbai. [8] On October 24, Kyarr washed ashore the chemical tanker Nu-Shi Nalini near Dona Paula in Goa state, which was carrying naphtha, an explosive. The material was salvaged about a month after the storm, and was eventually shipped in early January 2020. [9] Also offshore, the cyclone forced two AIDA cruise ships to reroute their paths. [10]
In advance of the tropical cyclone, the IMD issued rain and surf alerts for the Indian states of Maharashtra, Karnataka, and Goa. [11] As Kyarr approached western India, the cyclone dropped heavy rainfall onshore, peaking at 400 mm (16 in) in Malvan, Maharashtra. [3] In Goa, the rains caused flash flooding, while strong winds felled trees and power lines. [11] In Mumbai, the storm's heavy rains contributed to a dengue outbreak, with a 70% increase in cases of the mosquito-borne disease in December 2019 compared to the same month in 2018. [12] In Gujarat, more than 157,000 farmers filed insurance claims due to damage related to Kyarr, with most of the losses related to groundnut and cotton. The state government reimbursed farmers for their losses. [13] [14] 5 people killed from rain-related incidents in Karnataka, India. [2]
In southern Pakistan, officials closed beaches and opened four shelters due to high tides from the cyclone. Floods affected parts of Karachi, closing a section of Defence Raya Golf and Country Club. [15]
High tides from Kyarr flooded towns on the coast of Oman. [16] In neighboring United Arab Emirates, high tides flooded streets, houses, and schools in eastern coastal areas of Sharjah and Fujairah. [17] Heavy rainfall from the outskirts of Kyarr also caused flooding in Dubai. [10]
Kyarr started to slow down as it moved through the Arabian Sea, and it dissipated before reaching Socotra Island. [18] [19]
In the Indian Ocean north of the equator, tropical cyclones can form throughout the year on either side of the Indian subcontinent, although most frequently between April and June, and between October and December.
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.
Super Cyclonic Storm Gonu was an extremely powerful tropical cyclone that became the strongest cyclone on record in the Arabian Sea. The second named tropical cyclone of the 2007 North Indian Ocean cyclone season, Gonu developed from a persistent area of convection in the eastern Arabian Sea on June 1, 2007. With a favorable upper-level environment and warm sea surface temperatures, it rapidly intensified to attain peak winds of 240 km/h (150 mph) on June 4, according to the India Meteorological Department. Gonu weakened after encountering dry air and cooler waters, and early on June 6, it made landfall on the easternmost tip of Oman, becoming the strongest tropical cyclone to hit the Arabian Peninsula. It then turned northward into the Gulf of Oman, and dissipated on June 7, after making landfall in southern Iran, the first landfall in the country since 1898.
The 2000 North Indian Ocean cyclone season was fairly quiet compared to the year before, 1999 North Indian Ocean cyclone season, with all of the activity originating in the Bay of Bengal. The basin comprises the Indian Ocean north of the equator, with warnings issued by the India Meteorological Department (IMD) in New Delhi. There were six depressions throughout the year, of which five intensified into cyclonic storms – tropical cyclones with winds of 65 mph (105 km/h) sustained over 3 minutes. Two of the storms strengthened into a Very Severe Cyclonic Storm, which has winds of at least 120 km/h (75 mph), equivalent to a minimal hurricane. The Joint Typhoon Warning Center (JTWC) also tracked storms in the basin on an unofficial basis, estimating winds sustained over 1 minute.
The 1996 North Indian Ocean cyclone season featured several deadly tropical cyclones, with over 2,000 people killed during the year. The India Meteorological Department (IMD) – the Regional Specialized Meteorological Center for the northern Indian Ocean as recognized by the World Meteorological Organization – issued warnings for nine tropical cyclones in the region. Storms were also tracked on an unofficial basis by the American-based Joint Typhoon Warning Center, which observed one additional storm. The basin is split between the Bay of Bengal off the east coast of India and the Arabian Sea off the west coast. During the year, the activity was affected by the monsoon season, with most storms forming in June or after October.
The 1977 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation. 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 to the east of the Indian subcontinent and the Arabian Sea to the west of India. 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. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.
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 2001 Gujarat cyclone was the third strongest tropical cyclone, in terms of barometric pressure, to form in the Arabian Sea on record; only Cyclones Gonu in 2007 and Kyarr in 2019 were stronger. The storm originated from a tropical disturbance that formed east of Somalia on May 18. Over the following few days, the system gradually organized into a tropical depression. Tracking eastward, towards the coastline of southwestern India, the storm slowly intensified. Shortly before reaching shore, the system turned north and later west, away from land. After taking this turn, the storm intensified into a very severe cyclonic storm, attaining its peak intensity on May 24 with winds of 215 km/h and a barometric pressure of 932 mbar (hPa). At the time, this ranked the cyclone as the strongest known storm in the Arabian Sea.
India is a country in the north of Indian Ocean that is the most vulnerable to getting hit by tropical cyclones in the basin, from the east or from the west. On average, 2–3 tropical cyclones make landfall in India each year, with about one being a severe tropical cyclone or greater.
Extremely Severe Cyclonic Storm Nilofar was, at the time, the third-strongest cyclone in the Arabian Sea. In late October 2014, it reached peak maximum sustained winds estimated between 205 km/h (125 mph) and 215 km/h (130 mph). The India Meteorological Department (IMD) named it Nilofar; the name refers to the water lily, and was suggested by Pakistan. The western fringes of the storm caused flash flooding in northeastern Oman, killing four people.
The 2015 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. 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.
Extremely Severe Cyclonic Storm Chapala was a powerful tropical cyclone that caused moderate damage in Somalia and Yemen during November 2015. Chapala was the third named storm of the 2015 North Indian Ocean cyclone season. It developed as a depression on 28 October off western India, and strengthened a day later into a cyclonic storm. Chapala then rapidly intensified amid favorable conditions. On 30 October, the India Meteorological Department (IMD) estimated that Chapala attained peak three-minute sustained winds of 215 km/h (135 mph). The American-based Joint Typhoon Warning Center (JTWC) estimated sustained winds of 240 km/h (150 mph), making Chapala among the strongest cyclones on record in the Arabian Sea. After peak intensity, Chapala skirted the Yemeni island of Socotra on 1 November, becoming the first hurricane-force storm there since 1922. High winds and heavy rainfall resulted in an island-wide power outage, and severe damage was compounded by Cyclone Megh, which struck Yemen a week later.
The October 1996 India cyclone had an unusual and protracted path that spanned much of the northern Indian Ocean. It originated in a weather disturbance that formed on October 14 in the southern Bay of Bengal, off India's east coast. Moving westward, it struck Andhra Pradesh on October 17 as a well-defined low-pressure area. It crossed southern India and reorganized in the Arabian Sea off the western coast of India. The system developed into a depression on October 22 and quickly intensified while moving northward. By October 24, the cyclone approached hurricane intensity as it developed an eye, reaching peak winds of at least 110 km/h (70 mph). On October 25, the storm abruptly stalled and weakened off Gujarat, and progressed southwestward as a minimal storm. It was no longer classifiable as a tropical cyclone by October 28, although its remnants persisted until November 2 when they dissipated east of Somalia.
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 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 2019 North Indian Ocean cyclone season was the second most active North Indian Ocean cyclone season on record in terms of cyclonic storms, the 1992 season was more active according to the Joint Typhoon Warning Center. The season featured 12 depressions, 11 deep depressions, 8 cyclonic storms, 6 severe cyclonic storms, 6 very severe cyclonic storms, 3 extremely severe cyclonic storms, and 1 super cyclonic storm, Kyarr, the first since Cyclone Gonu in 2007. Additionally, it also became the third-costliest season recorded in the North Indian Ocean, only behind the 2020 and 2008 seasons.
The 2020 North Indian Ocean cyclone season was the costliest North Indian Ocean cyclone season on record, mostly due to the devastating Cyclone Amphan. 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 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.
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.
