North Indian Ocean tropical cyclone seasons
2017, 2018, 2019, 2020, 2021

The 2019 North Indian Ocean cyclone season is an ongoing 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 April and December, with two peaks in activity 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's first named storm, Pabuk, entered the basin on January 4, becoming the earliest-forming cyclonic storm of the North Indian Ocean on record. The second cyclone of the season, Fani, was the strongest tropical cyclone in the Bay of Bengal by 3-minute maximum sustained wind speed and minimum barometric pressure since the 1999 Odisha cyclone (while being equal in maximum 3-minute sustained wind speed to Phailin of the 2013 season).

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 (JTWC) and the National Meteorological Center of CMA (NMC) unofficially release full advisories. On average, three to four cyclonic storms form in this basin every season.[1][2]

Season summary[edit]

Cyclone VayuCyclone FaniTropical Storm Pabuk (2019)

Due to the presence of an weak El Niño to continue through the season, the season's first named storm, Pabuk, entered the basin on January 4, becoming the earliest-forming cyclonic storm of the North Indian Ocean on record, tying with 2014 season. The second Cyclonic Storm of the season was formed, Fani on April 26. Fani became an extremely severe cyclonic storm on April 30, reaching an Category 4-equivalent tropical cyclone on the Saffir-Simpson Scale, then made landfall in India killing 89 people between Odisha and Bangladesh; Fani caused $1.812 billion in damages. In early June, a strong pulse of the Madden-Julian Oscillation (MJO), the third cyclonic storm, Vayu formed on June 10 in the Arabian Sea near Maldives, then it turned into a very severe cyclonic storm on June 12 after moving northwest Pakistan and India..

Systems[edit]

Cyclonic Storm Pabuk[edit]

DurationJanuary 4 (Entered basin) – January 7
Peak intensity85 km/h (50 mph) (3-min)  998 hPa (mbar)

Originally a tropical storm that formed over the South China Sea on January 1, Pabuk entered the Gulf of Thailand two days later. Shortly afterward, Pabuk made landfall over southern Thailand on January 4 and crossed into the Andaman Sea, and the IMD initiated advisories on the storm, making Pabuk the earliest-forming cyclonic storm for this basin, surpassing Hibaru in 2005, as well as the first cyclonic storm with a name originally assigned by RSMC Tokyo.[3] Over the few days of days, Pabuk continued moved west-northwestward, before weakening into a well-marked low on January 7. The system's remnant low then turned to the northeast, subsequently dissipating on January 8.

Extremely Severe Cyclonic Storm Fani[edit]

On April 26, a depression formed to the west of Sumatra, with the IMD giving the storm the identifier BOB 02. The system slowly organized while curving towards the northeast. On April 27, at 00:00 UTC, the IMD upgraded the system to a deep depression.[4] Later that day, the system intensified into Cyclonic Storm Fani, while shifting to the northwest. Development of the system proceeded very slowly for several days, with the cyclone struggling to intensify against the influence of moderate vertical wind shear.[5] At 12:00 UTC on 29 April, Fani was upgraded to a severe cyclonic storm, with the system beginning to undergo rapid intensification.[6][7] Fani continued rapidly intensifying, becoming an extremely severe cyclonic storm at 17:00 UTC on April 30.[8] The Joint Typhoon Warning Center (JTWC) upgraded the system to a Category 4 tropical cyclone on the Saffir–Simpson scale at 06:00 UTC on May 2, following which, rapid intensification resumed. Three-minute sustained winds increased to 215 km/h (130 mph), and one-minute sustained winds to 250 km/h (155 mph), making the system the equivalent of a high-end Category 4 major hurricane. On May 3, at 02:30 UTC (8:00 a.m. IST) Fani made landfall on Puri, in Odisha,[9][10] weakening to a Category 1-equivalent very severe cyclonic storm soon after landfall, subsequently weakening to a cyclonic storm several hours later.[11] On May 4, Fani weakened into a deep depression and moved into Bangladesh.[12] Later that day, Fani degenerated into a well-marked low,[13] before dissipating on the next day.

Very Severe Cyclonic Storm Vayu[edit]

Peak intensity150 km/h (90 mph) (3-min)  978 hPa (mbar)

In early June, a strong pulse of the Madden-Julian Oscillation (MJO) tracked eastwards into the tropical Indian Ocean, leading to increased cloudiness and rainfall across the region.[14] On June 9, the India Meteorological Department (IMD) noted the development of a low-pressure area over the southeastern Arabian Sea, to the north of the Maldives. Early on June 10, a depression formed in the Arabian Sea, just northwest of the Maldives, and the IMD gave the storm the identifier ARB 01. As the system moved northward, it gradually strengthened, becoming a deep depression, before intensifying further into Cyclonic Storm Vayu later that day. After being upgraded by the IMD to a severe cyclonic storm on June 11, and concurrently by the JTWC to a Category 1 tropical cyclone on the Saffir–Simpson hurricane wind scale (SSHWS), the system began a period of rapid intensification. Vayu strengthened into a very severe cyclonic storm soon afterward, and became a Category 2-equivalent very severe cyclonic storm on June 12. On June 13, the influence of a strengthening subtropical ridge over Saudi Arabia caused Vayu to gradually slow down and turn to the west, as it approached the coastline of the state of Gujarat in northwestern India.[15][16] Later that day, at 12:00 UTC, Vayu reached its peak intensity as a Category 3-equivalent tropical cyclone, with one-minute sustained winds of 185 km/h (115 mph).[17] On June 14, Vayu began to weaken, as it tracked slowly westward, away from the Gujarat coastline due to strong wind shear.[18]

Storm names[edit]

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 members of the ESCAP/WMO Panel on Tropical Cyclones between 2000 and May 2004, before the Regional Specialized Meteorological Center in New Delhi started to assign names in September 2004. 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 the Western Pacific, it will retain its original name. The next six available names from the List of North Indian Ocean storm names are below.

  • Hikaa (unused)
  • Kyarr (unused)
  • Maha (unused)
  • Bulbul (unused)

Pabuk entered the basin from the Gulf of Thailand as a cyclonic storm; its name was assigned by the Japan Meteorological Agency.
