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.



Headline:

Tropical Cyclone Marcus is crossing the far north Kimberley coast north of Wyndham.

Areas affected:

Warning zone: Wyndham to Beagle Bay, NOT including Wyndham or Derby.

Watch zone: None.

Cancelled zones: Wyndham to the WA/NT Border..


Details of Tropical Cyclone Marcus at 8:00 am AWST:

Intensity: category 2, sustained winds near the centre of 100 kilometres per hour with wind gusts to 140 kilometres per hour.
Location: within 30 kilometres of 14.2 degrees South, 127.7 degrees East , 115 kilometres east of Kalumburu and 150 kilometres north northwest of Wyndham .
Movement: west southwest at 16 kilometres per hour .

Tropical Cyclone Marcus is crossing the far north Kimberley coast as a Category 2 system. As the system tracks west to southwest over the far northern Kimberley today it will gradually weaken and is likely to become a Category 1 system later today. Once TC Marcus moves back over the ocean off the northwest Kimberley overnight or early Monday morning, it will re-intensify and become a Severe Tropical Cyclone. The system will track westwards away from the WA mainland from Monday with no further impact on northern communities.


Hazards:

GALES with gusts to 120 kilometres per hour along the northern Kimberley coast between Kalumburu and the coast north of Wynham should extend through remaining parts of the north Kimberley, including Kalumburu and Mitchell Plateau during Sunday. These winds will become confined to coastal parts between Mitchell Plateau and Cockatoo Island by early Monday morning and may extend as far south as Beagle Bay during Monday afternoon.

DESTRUCTIVE winds with gusts greater than 150 kilometres per hour near the centre of Tropical Cyclone Marcus are possible as it passes over the far north Kimberley during Sunday.

Tropical Cyclone Marcus is forecast to move off the northwest Kimberley coast on Monday morning and will not move far enough south to have any significant impact on Broome or Derby.

Tides between Kalumburu and the WA/NT Border are likely to rise above the normal high tide mark during Sunday morning, with very rough seas and flooding of low-lying coastal areas.

HEAVY RAIN is expected to develop over the north Kimberley during Sunday and Monday, and a Flood Watch is current.


Recommended Action:

DFES advises of the following community alerts:

RED ALERT: People in or near coastal and island communities from Wyndham to Mitchell Plateau, including Kalumburu and Mitchell Plateau but NOT including Wyndham, should remain in shelter.

YELLOW ALERT: People in or near coastal and island communities from Mitchell Plateau to Cockatoo Island, including Cockatoo Island but NOT including Mitchell Plateau, need to take action and get ready to shelter from a cyclone.

BLUE ALERT: People in or near coastal and island communities from Cockatoo Island to Beagle Bay, but NOT including Derby or Cockatoo Island, need to prepare for cyclonic weather.

ALL CLEAR: People in the community of Wyndham are advised that the cyclone danger has passed.
