Bakung
2025-26 season · AU202526_05U
History
Severe Tropical Cyclone Bakung developed on 10 December when a low-pressure area formed south of Jakarta. Although initially outside its area of responsibility, the Bureau of Meteorology designated the system Tropical Low 05U. As it moved southwest and organised, TCWC Jakarta named it Bakung on 12 December. The cyclone intensified rapidly in conditions of low wind shear, reaching its peak intensity as a Category 4 system on 14 December after moving into the Australian area of responsibility. Increasing wind shear caused the system to weaken during 15–16 December, though a temporary easing of shear allowed Bakung to briefly regain Category 3 intensity in the early hours of 17 December. Wind shear then rapidly strengthened again, reducing Bakung to a tropical low before it dissipated on 18 December. Throughout its lifetime, Bakung tracked through the northwestern part of the Australian basin in a looping path and did not make landfall. No significant impacts to populated areas or coastlines were recorded in association with this system.
