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 Marcus is passing between Melville Island and Cobourg Peninsula. The cyclone is expected to continue moving southwest near the Melville Island coast, and may briefly develop into a Category 2 system, although may weaken again as it interacts with the surrounding coastline. The tropical cyclone is expected to pass close to Darwin during Saturday, before moving into the Timor Sea late on Saturday. During Sunday, Tropical Cyclone Marcus is expected to reach Category 2 intensity before it approaches the north Kimberley coast.

Hazards:

GALES with gusts to 120 km/h are currently occuring over parts of Melville Island and Cobourg Peninsula to Croker Island. Gales are expected to be easing between Croker Island and Goulburn Island.

DESTRUCTIVE WINDS with gusts greater than 130 km/h may develop over eastern parts of Melville Island overnight as the tropical cyclone strengthens to category 2.

Gales are expected to extend to Darwin and the remainder of the Tiwi Islands early Saturday morning as the tropical cyclone passes through the Van Diemen Gulf.

Gales may extend to Daly River Mouth by Saturday afternoon and further south to the WA/NT border later on Saturday or Sunday as the tropical cyclone moves into the Timor Sea. Gales are expected to extend to the north Kimberley during Sunday, and destructive winds may develop over the Kimberley coast later on Sunday as the cyclone strengthens to Category 2.

A STORM TIDE between Milikapiti and Goulburn Island, including the Van Diemen Gulf, is expected as the cyclone centre crosses the coast tonight. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING tonight and into Saturday morning.

Tides will be HIGHER THAN NORMAL between Daly River Mouth and Cape Hotham, including Darwin. Large waves may produce MINOR FLOODING of low-lying coastal areas during Saturday as the cyclone moves past.

HEAVY RAIN is expected over the northwest Top End tonight and on Saturday.
