Meteorological history

On 4 January, the Bureau of Meteorology (BoM) began to monitor the northern

for potential tropical cyclogenesis, as the monsoon trough was forecast to have renewed activity. Four days later, the BoM reported that a tropical low had formed, and designated it as ''10U''. At the same time, the Joint Typhoon Warning Center (JTWC) gave it a low chance of formation into a tropical cyclone within 24 hours, and the unofficial identifier ''Invest 90P''. At the time, the low was located within a marginal environment for further development, with warm, sea surface temperatures, moderate to high wind shear, and radial outflow aloft. Within the next 12 hours, the system's

began consolidating, along with deep convection persisting around it, prompting the JTWC to upgrade its chances of development into medium, before subsequently issuing a Tropical Cyclone Formation Alert (TCFA) at 23:30 UTC that same day, noting a small eye feature and improved curved banding on microwave imagery. At 06:00 UTC the next day, the BoM upgraded the tropical low into a category 1 tropical cyclone in the Australian scale, and named it ''Tiffany''. The JTWC subsequently upgraded Tiffany into a tropical storm in the Saffir-Simpson scale three hours later, noting the rapid organization of the system in 12 hours. Moving west under a deep-layered subtropical ridge to its south, Tiffany went on a rapid intensification phase, with the BoM upgrading the storm to a Category 2 tropical cyclone six hours later. Tiffany then peaked at 21:00 UTC that same day, with 10-minute sustained winds of , and 1-minute sustained winds of , becoming a category 1-equivalent cyclone on the Saffir-Simpson scale. Tiffany then rapidly weakened into a category 1 tropical cyclone due to wind shear as it moved over the

on 11 January. Upon entering the Gulf of Carpentaria, it started to restrengthen, under a favorable environment of moderate wind shear being offset by very warm, sea surface temperatures, and strong outflow. At 12:00 UTC that same day, the BoM upgraded Tiffany back into a category 2 tropical cyclone, as the system continued to reintensify. Tiffany then reached its secondary peak intensity later that day, with 10-minute sustained winds of , and 1-minute sustained winds of . At 00:00 UTC (09:30 ACST) 12 January, Tiffany made its final landfall at

in the Northern Territory. The JTWC subsequently issued their final advisory on the system three hours later. Tiffany then weakened into a remnant low and remained traceable overland as it moved west, reaching the Western Australia region on 13 January, before turning southeast in response to a mid-latitude trough moving from the west. It was last noted on 17 January, over central Australia.

No direct impacts on Papua New Guinea were reported, though of rainfall fell in the southern half of the country.

Australia

As the system was strengthening to the west of the Cape York Peninsula, cyclone warnings were issued over the region. Tiffany hit many areas still recovering from swells caused by Cyclone Seth. One person died in Queensland after floodwaters struck them, and another person is currently missing. Damage in the Cape York Peninsula was minimal, though many people were urged to hide in shelters or basements. Many people across Queensland, most in
