The monsoon trough was active through the Gulf of Carpentaria during early January. A number of low pressure centres formed along it during the period January 9th-10th, with the centre that eventually became Tropical Cyclone Charlotte forming in the central Gulf late on the 10th. The system was named during the late morning on Sunday 11 January.
TC Charlotte continued to track slowly to the east-southeast and crossed the coast near the Gilbert River Mouth during the early morning on Monday January 12th. TC Charlotte then quickly decayed into a rain depression as it moved inland.
Heavy rainfall associated with the rain depression and monsoon trough subsequently occurred over the catchments of the already flooded Gulf rivers.
