8 - 17 January 2022
Best Track of Tropical Cyclone Tiffany

Summary

A small tropical low formed in the northern Coral Sea on 8 January and developed quickly reaching category 1 cyclone strength in the afternoon of 9 January over waters to the northeast of Cooktown. Tropical Cyclone Tiffany intensified further during 9 January reaching category 2 intensity in the evening while moving west towards the far north Queensland coast.

Tiffany crossed the Cape York Peninsula near Cape Melville during the 10 January at category 2 intensity. Tiffany moved westwards over Cape York Peninsula and weakened below tropical cyclone intensity during evening of 10 January. The cyclone brought up to 170 mm of rainfall across the Daintree and Mossman Rivers in the 24 hours to 9am Tuesday 11 Jan, and isolated rainfall totals of up to 230 mm were recorded around the Holroyd River.

The system emerged over the Gulf of Carpentaria near Pormpuraaw during the morning of 11 January and re-intensified to category 1 intensity the same day whilst tracking west over the Gulf of Carpentaria.

Tropical Cyclone Tiffany crossed the Northern Territory coast near Port Roper on the morning of Wednesday 12 January as a category 1 system and Ngukurr recorded a 91 km/h wind gust. Tiffany weakened quickly into a rain-bearing depression as it tracked over land just west of Ngukurr (around 235 kilometres east of Katherine).

Ex-tropical cyclone Tiffany then tracked westwards across the NT. Heavy rainfall near the Katherine region led to major flooding in the Waterhouse River, at Beswick Bridge and minor flooding for the Katherine River. Lines of fast-moving thunderstorms ahead of the cyclone moved over Groote Eylandt and the Katherine region, causing significant vegetation and property damage on 11, 12 and early on 13 January.

The remnants of the low moved slowly across the Kimberley region of Western Australia on 14 and 15 January. Ex-TC Tiffany then turned southeast and brought rainfall to inland WA and the arid southern half of the Northern Territory. Heavy rain also to South Australia disrupted rail and road transportation.

Tropical Cyclone Tiffany was the fourth tropical cyclone in the Australian region for the 2021/22 season.
