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.

Tropical Cyclone Trevor is located over the eastern Gulf of Carpentaria and is expected to rapidly intensify to a category 3 cyclone by this evening.
Tropical Cyclone Trevor will intensify further as it adopts a more general west-southwest movement across the Gulf of Carpentaria later today. It is likely to cross the Northern Territory coast during Saturday as a category 4 severe tropical cyclone.
GALES, with gusts in excess of 90 km/h, are occurring near the centre of the cyclone. GALES are expected to extend across western parts of Cape York Peninsula today, to impact areas between Mapoon and Kowanyama, including Aurukun and Weipa as the cyclone intensifies just off the coast.
DESTRUCTIVE WINDS, with gusts in excess of 130 km/h may develop between Weipa and Cape Keerweer during this afternoon as the cyclone rapidly intensifies.
GALES, with gusts in excess of 90 km/h, may develop from the NT/QLD border to Karumba, including Mornington and Sweers Islands during Friday if the cyclone takes a more southerly track.
As the cyclone intensifies through today, a STORM TIDE is expected between Mapoon and Aurukun on this afternoon's high tide. Large waves may produce minor flooding along the foreshore. People living in areas likely to be affected by this flooding should take measures to protect their property as much as possible and be prepared to help their neighbours.
HEAVY RAINFALL, which may lead to flash flooding, and DAMAGING WINDS are possible across parts of the Cape York Peninsula district and a separate Severe Weather Warning is current.
Flood Warnings are current for the Daintree and Mossman Rivers as well as a broader Flood Watch for catchments north of Innisfail to Kowanyama.
FOR THE NORTHERN TERRITORY COASTAL AREAS:
GALES, with gusts to 120 km/h are expected to develop on Groote Eylandt from Friday morning and extend to the mainland coast between Cape Shield and the Northern Territory/Queensland border later on Friday and then inland into the eastern Carpentaria District on Friday evening. GALES could also extend further north to Nhulunbuy on Friday if the cyclone takes a more northerly track.
The VERY DESTRUCTIVE core of Severe Tropical Cyclone Trevor is forecast to cross the southwestern coast of the Gulf of Carpentaria between Groote Eylandt and the NT/QLD Border during Saturday with VERY DESTRUCTIVE WINDS, with gusts to 275 km/h near the cyclone centre as it approaches and crosses the coast.
Coastal residents between Groote Eylandt and the NT/Qld border are specifically warned of a VERY DANGEROUS STORM TIDE as the cyclone centre approaches the coast. Tides will rise significantly above the normal high tide, with DAMAGING WAVES and VERY DANGEROUS FLOODING during Friday evening and Saturday.
