In 2023, tropical cyclones formed 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 {{convert|35|knots|km/h mph|round=5}}. So far 2 systems formed with 1 of them being named.

Tropical cyclones are primarily monitored by ten warning centers across the world, designated as a [[Regional Specialized Meteorological Center]] (RSMC) or a [[Tropical Cyclone Warning Center]] (TCWC) by the [[World Meteorological Organization]] (WMO).

In 2023, tropical cyclones formed 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 3 systems formed with 1 of them being named.

Tropical cyclones are primarily monitored by ten warning centers across the world, designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization (WMO). These ten centers are the National Hurricane Center (NHC), the Central Pacific Hurricane Center (CPHC), the Japan Meteorological Agency (JMA), the Indian Meteorological Department (IMD), Météo-France (MFR), Indonesia's Badan Meteorologi, Klimatologi, dan Geofisika, the Australian Bureau of Meteorology (BoM), Papua New Guinea's National Weather Service, the Fiji Meteorological Service (FMS), and New Zealand's MetService. Other notable warning centers include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the United States's Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

Two tropical systems active on January 6th, 2023 near Australia across two basins - Tropical Low 07U; which eventually became Hale (middle), and Tropical Disturbance 03F (right). Post-Tropical Cyclone Ellie can be seen to the left of 07U.
Main article: 2022–23 Australian region cyclone season

On December 23, 2022, the BoM released its last bulletin on Tropical Cyclone Ellie, which formed in December of 2022, as the system weakened into a tropical low.[1] However, Ellie remained traceable,[2] as it moved southwest towards the Western Australia region throughout the rest of December.[3] The BoM then gave the tropical low a moderate chance of redeveloping into a tropical cyclone on 1 January.[4]

By 31 December, the BoM noted the potential of a tropical low forming over the Coral Sea, as the monsoon was forecast to strengthen further over the region.[5] 3 days later, the agency put a low chance for the potential low to develop into a tropical cyclone in the region.[6] By 6 January, the BoM reported that Tropical Low 07U had developed approximately 190 km (120 mi) to the north-northeast of Townsville in Queensland.[7] The JTWC gave it a medium chance to develop into a tropical cyclone, and dubbed the system as Invest 93P.[8] At around 12:00 UTC on January 6, the JTWC released a TCFA (Tropical Cyclone Formation Alert), saying that the chance for the system to develop into a tropical cyclone was high.[9]With a favorable environment of low wind shear, warm sea surface temperatures, and good radial outflow, the system intensified into a tropical cyclone late on the same day according to the JTWC, and designating it as 07P.[10] The BoM did not upgrade 07U as such, citing that its center was elongated northwest to the southeast.[11] 07U then later exited the basin and moved into the South Pacific basin.[12]

Late on January 5, the FMS reported that Tropical Disturbance 03F had formed near New Caledonia.[13] On January 8, the JTWC gave the system's chance for development as low, although in favorable environment, it was in close proximity with Hale.[14] Later that day, at 15:00 UTC, the JTWC issued its final advisory on the system, since the convection dissipated. It was no longer suspect for development into a significant tropical cyclone, however, upon reanalysis, it was shown that winds picked up to 35 knots, convection re-fired, and an eye-feature was visible, so the agency gave the system a medium chance to develop into a tropical cyclone.[15] However at 9:00 UTC on January 9, the JTWC issued its last advisory on the system, since although it was still identifiable on satellite imagery, the agency was saying it was approaching the strong gradient to its south, so subtropical transition and incorporation within the boundary would have been inevitable.[16]

On January 7, Tropical Low 07U moved into the basin from the Australian region, when it was immediately reclassified as Tropical Depression 04F by the FMS.[17] Late on the same day, it intensified into a Category 1 tropical cyclone, with the FMS naming it as Hale.[18] Deep convection near the system was initially only fragmented; however, environmental conditions were assessed as being conducive for development, with moderate vertical wind shear, good upper-level outflow and sea surface temperatures 27 °C (81 °F).[19] The JTWC's discontinued warnings on the system around 09:00 UTC on January 9.[20] The system moved into MetService's area of responsibility, before they reclassified it as an extratropical low later that day.[21]

There are a total of 7 tropical cyclone basins that tropical cyclones typically form in. In this table, data from all these basins are added. [22]

  1. ^ a b The wind speeds for this tropical cyclone/basin are based on the Saffir Simpson Scale which uses 1-minute sustained winds.
  2. ^ a b c d Only systems that formed either before or on December 31, 2023 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. ^ a b c Only systems that formed either on or after January 1, 2023 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.
