Best Track of Tropical Cyclone Imogen
All times shows are in Australian Eastern Standard Time (AEST), that is UTC + 10 hours.

Tropical cyclone Imogen was the first cyclone to form in the Gulf of Carpentaria region for the 2020-21 season. Imogen was a short-lived cyclone having lived for six hours before making landfall near Karumba on the Gulf of Carpentaria coast. The cyclone caused minor damage to vegetation and infrastructure in the region as it made landfall on 3 January. Moving inland, it brought heavy rainfall and flooding to north Queensland causing disruptions to transportation.  

A weak low-pressure system developed near Groote Eylandt in Northern Territory on 1 January. The tropical low then tracked south-eastwards across the Gulf of Carpentaria, moving parallel to the southern Gulf coast. The low passed over the Mornington Island on 3 January indicating near gale winds completely wrapping around the centre.

The Mornington Island radar imagery and observations indicated the low was close to being a cyclone. The system was named tropical cyclone Imogen as soon as it moved off the Mornington Island coast at 4pm on 3 January.

The cyclone intensified slightly as it accelerated towards the coast, making landfall in the next six hours of being named.

Imogen brought heavy rainfall, large waves, abnormally high tides reaching above the Highest Astronomical Tide and sustained strong gales as it made landfall near Karumba. These hazards brought minor damages  to the vegetation and infrastructure in the region.
