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

GALES, with gusts in excess of 90 km/h, are occurring near the centre of the

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

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.

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.
