GALES with gusts to 100 kilometres per hour are possible over coastal parts of the northwest Kimberley between Mitchell Plateau and Cockatoo Island at the moment. Conditions are expected to ease from the west during the morning. These winds may extend as far south as Beagle Bay during Monday morning then ease in the afternoon.

Tropical Cyclone Marcus will continue moving westwards over the next few days and remain well offshore from the WA coast. It will not move far enough south to have any significant impact on Broome, Derby or the Pilbara coast.

HEAVY RAIN is occurring near the system in the coastal northwest Kimberley, but should be on an easing trend as TC Marcus moves further offshore. A Flood Warning is current, see www.bom.gov.au/wa/warnings for details.
