The forecast path shown above is the Bureau's best estimate of the cyclone's future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre.

Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning and watch zones reflects this.

This product is designed for land-based communities; mariners should read the coastal waters and high seas warnings.

Ex-Tropical Cyclone Tiffany lies in the Gulf of Carpentaria. It is expected to redevelop into a tropical cyclone overnight or early Wednesday while tracking steadily towards the west. On Wednesday the system will approach the eastern Northern Territory coast where category 2 tropical cyclone impacts are possible. Tropical Cyclone Tiffany will then continue moving westwards, weakening below cyclone strength over land near the base of the Top End on Wednesday night.

Hazards:

GALES are expected to develop about Groote Eylandt and Port McArthur from early Wednesday morning. GALES may develop in remaining parts between Nhulunbuy and the NT/Qld border during Wednesday depending on the track of the system.

The tropical cyclone is expected to cross the coast on Wednesday afternoon, most likely in the area around Port Roper and Nathan River, with DESTRUCTIVE wind gusts to 140 km/h possible close the system centre.

GALES with wind gusts to 100 km/h may extend inland to areas to the east of Beswick late on Wednesday as the cyclone moves inland before weakening.

A STORM TIDE between the NT/Qld border and Cape Shield, including Groote Eylandt, is expected as the cyclone centre passes Groote Eylandt and makes landfall on the mainland coast Wednesday afternoon. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING between the NT/Qld border and Cape Shield, including Groote Eylandt during Wednesday and early Thursday morning.

HEAVY RAIN is likely to develop across parts of the Arnhem and Carpentaria Districts from Wednesday and is expected to cause flooding of low lying areas and river rises. Heavy rain is also likely to extend westwards into the Daly District on Thursday.
