Australian region tropical cyclone seasons
2022–23, 2023–24, 2024–25, 2025–26, 2026–27

The 2024–25 Australian region cyclone season is an ongoing weather event in the southern hemipshere. The season has officially started on 1 November 2024 and will end on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones will be officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the Australian Bureau of Meteorology, National Weather Service of Papua New Guinea and the Indonesian Agency for Meteorology, Climatology and Geophysics. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and the Fiji Meteorological Service will also monitor the basin during the season.

Ahead of the season officially starting on 1 November, the Australian Bureau of Meteorology (BoM) and New Zealand's National Institute of Water and Atmospheric Research (NIWA) both issued a tropical cyclone outlook that discussed the upcoming season.[2][3] These outlooks took into account a variety of factors such as a developing weak to moderate La Niña event and what had happened in previous seasons such as 1983–84, 1995–96, 2005–06 and 2017–18.[2][3] The Southwest Pacific tropical cyclone outlook issued by New Zealand's National Institute of Water and Atmospheric Research (NIWA) in conjunction with MetService, the BoM and various other Pacific meteorological services, predicted that six to ten tropical cyclones would occur over the South Pacific Ocean between 135°E and 120°W.[3] The outlook also predicted that three to four of these tropical cyclones would intensify further and become either a Category three, four or five severe tropical cyclone on the Australian tropical cyclone intensity scale.[3] In addition to contributing towards the Southwest Pacific tropical cyclone outlook, the BoM predicted that tropical cyclone activity within the whole region between 90°E – 160°E and each of its self defined subregions would be near normal.[2] They also warned that the likelihood of a severe tropical cyclone was higher than average because of the warmer than average ocean temperatures that had been forecast for the region.[2]

Tropical low (Australian scale)
 
Duration18 November – Present
Peak intensity35 km/h (25 mph) (10-min);

In Indonesia, the unnamed tropical low caused widespread heavy rainfall in Sumatra and Java, with much of the country's coastline expected to experience waves of 1.25–2.5 m (4.1–8.2 ft).[4] In Padang Lawas Regency, North Sumatra, four members of a family were killed and several others were injured by a landslide which severely damaged two houses.[5] In Sibolangit, floods caused four deaths, injured nine and left two missing.[6] Severe flooding in South Tapanuli Regency killed two people, left two missing, injured 76, destroyed 16 houses and damaged 345 others, with three villages recording severe damage.[7][8][9] In Lima Puluh Kota Regency, West Sumatra, flooding left one person dead and another missing.[10] A child drowned at Subulussalam, Aceh, where 17 villages were flooded.[11] Additionally, four people were killed by a landslide in Purworejo Regency[12] and a man died after a river overflowed at Semarang, Central Java.[13] Landslides also damaged 48 houses in three villages in Cianjur, West Java.[14]

Storm names

[edit]

Bureau of Meteorology

Main article: Tropical cyclone naming § Australian region (90°E – 160°E)

The Australian Bureau of Meteorology (TCWC Melbourne) monitors all tropical cyclones that form within the Australian region, including any within the areas of responsibility of TCWC Jakarta or TCWC Port Moresby.[15] Should a tropical low reach tropical cyclone strength within the BoM's area of responsibility, it will be assigned the next name from the following naming list. The names that will be used for the 2024–25 season are listed below:

  • Robyn (unused)
  • Sean (unused)
  • Taliah (unused)
  • Vince (unused)
  • Zelia (unused)
  • Anthony (unused)
  • Bianca (unused)
  • Courtney (unused)
  • Dianne (unused)
  • Errol (unused)
  • Fina (unused)
  • Grant (unused)

TCWC Jakarta

[edit]

TCWC Jakarta monitors Tropical Cyclones from the Equator to 11°S and from 90°E to 145°E. Should a Tropical Depression reach Tropical Cyclone strength within TCWC Jakarta's Area of Responsibility then it will be assigned the next name from the following list.[15]

  • Bakung (unused)
  • Cempaka (unused)
  • Dahlia (unused)
  • Flamboyan (unused)
  • Kenanga (unused)
  • Lili (unused)

TCWC Port Moresby

[edit]

Tropical cyclones that develop north of 11°S between 151°E and 160°E are assigned names by the Tropical Cyclone Warning Centre in Port Moresby, Papua New Guinea. Tropical cyclone formation in this area is rare, with no cyclones being named in it since 2007.[16] As names are assigned in a random order, the whole list is shown below:

  • Alu (unused)
  • Buri (unused)
  • Dodo (unused)
  • Emau (unused)
