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).

Tropical cyclones are primarily monitored by 10 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.

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,[1] it made landfall in Morombe District, Madagascar,[2] killing ten people.[3] After a brief lull in activity, Tropical Storm Belal formed on January 11.[4]

January - June

After a brief lull in activity, Tropical Low 04U would form northwest of the Cocos Islands on January 10.[5] The next day, Tropical Low 03U would form in the southern Joseph Bonaparte Gulf.[6] The day after that, Tropical Low 05U would form.[7]

Systems

January

So far, January has featured four systems, with one of them being named. Tropical Storm Alvaro from the South-West Indian Ocean would persist into 2024 and made landfall in Madagascar, killing 10 people and causing some damages.

  1. 1 2 The wind speeds for this tropical cyclone/basin are based on the Saffir Simpson Scale which uses 1-minute sustained winds.
  2. 1 2 3 4 Only systems that formed either before or on December 31, 2024 are counted in the seasonal totals.
  3. ↑ The wind speeds for this tropical cyclone/basin are based on the IMD Scale which uses 3-minute sustained winds.
  4. 1 2 3 Only systems that formed either on or after January 1, 2024 are counted in the seasonal totals.
  5. ↑ The wind speeds for this tropical cyclone are based on Météo-France, which uses wind gusts.
  6. ↑ The sum of the number of systems in each basin will not equal the number shown as the total. This is because when systems move between basins, it creates a discrepancy in the actual number of systems.
