In 2024, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain maximum sustained winds of 35 knots (65 km/h; 40 mph). So far, fifteen systems have formed, with seven of them being named. The most intense storm of the year so far is Anggrek, with a minimum pressure of 950 hPa (28.05 inHg). Among this year's systems, only one became a major tropical cyclone, with no tropical cyclones intensifying into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS). The accumulated cyclone energy (ACE) index for the 2024 (seven basins combined) so far, as calculated by Colorado State University (CSU) is 53.1 units overall.
Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization (WMO). These centers are: National Hurricane Center (NHC), Central Pacific Hurricane Center (CPHC), Japan Meteorological Agency (JMA), Indian Meteorological Department (IMD), Météo-France (MFR), Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), Australian Bureau of Meteorology (BoM), Papua New Guinea's National Weather Service (PNGNWS), Fiji Meteorological Service (FMS), and New Zealand's MetService. Unofficial, but still notable, warning centers include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA; albeit official within the Philippines), the United States's Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.
Global atmospheric and hydrological conditions
After the New Year, the MJO's amplitude weakened, with its eastward propagation slowing down due to the positive phase of the Indian Ocean Dipole (IOD) and an equatorial Rossby wave. Despite that, the MJO briefly caused El Niño-like wind anomalies to become easterly at the Date Line. There was also a significant increase in convection across the eastern Indian Ocean in January as the Dipole began weakening.[1] However, in the middle of January, the MJO began steadily intensifying, enhancing convection across the Maritime Continent. Despite that, intra-seasonal activity persevered,[2] although the MJO produced convection in the Western Pacific.[3] In Australia, the monsoonal trough's arrival was delayed until January 10, possibly due to the El Niño event.[4]
Summary
North Atlantic Ocean
Eastern & Central Pacific Oceans
Western Pacific Ocean
North Indian Ocean
South-West Indian Ocean
January - June
The first system of the season, Tropical Storm Alvaro, formed on December 30, 2023 and persisted into 2024. Before becoming post-tropical on January 3,[5] it made landfall in Morombe District, Madagascar,[6] killing nineteen people. After a brief lull in activity, Tropical Cyclone Belal formed on January 11.[7] severely affecting Mauritius and Réunion, with the latter suffering the brunt of the storm, causing six deaths in the process.[8][9] On January 22, Moderate Tropical Storm Candice formed.[10] Eight days later, Tropical Depression 05 formed.[11]
Australian Region
January - June
After a brief lull in activity, Tropical Cyclone Anggrek would form northwest of the Cocos Islands on January 10.[12] The next day, Tropical Low 03U would form in the southern Joseph Bonaparte Gulf.[13] The day after that, Tropical Cyclone Kirrily would form.[14] On 30 January, Subtropical Low 06U formed.
South Pacific Ocean
January - June
After a significant lull in activity, Tropical Disturbance 04F formed on January 25 and dissipated the next day.[15] On February 1, 6U entered the South Pacific basin and was designated 05F by the FMS.[16] After the system exited to the Australian region and struggled against moderate wind shear, 05F re-entered on February 7 and JTWC designated it tropical storm 12P.[17] On February 3, the FMS designated 06F and was later named Nat on February 5. The FMS upgraded Nat to a Category 2 tropical cyclone the next day before wind shear led to the system's demise.[18] Simultaneously, Tropical Disturbance 07F formed on February 5 before dissipating.[19] 08F quickly developed and the FMS named Osai on February 7 before an increase in wind shear caused the storm to dissipate.[20]
South Atlantic Ocean
On February 16, 2024, the CHM reported in its special bulletin and disclosed in its synoptic chart the formation of a subtropical depression in the Rio de Haneiro basin. [21]
Systems
January
January was slightly active with eight systems forming, four of them being named. Tropical Storm Alvaro from the South-West Indian Ocean persisted into 2024 and made landfall in Madagascar, killing nineteen and causing some damages. Cyclone Belal affected Reunion and Mauritius, causing six fatalities. In the Australian region, Cyclone Kirrily affected Queensland while Cyclone Anggrek formed in the basin, entered the South-West Indian Ocean on January 25, and became a Category 4-equivalent tropical cyclone on January 28, making it the strongest storm of the month, as well as the first major tropical cyclone of the year.
