Details of Severe Tropical Cyclone Nora at 6:30 pm ACST [7:00 pm AEST]:

Intensity: Category 3, sustained winds near the centre of 120 kilometres per hour with wind gusts to 165 kilometres per hour.

Location: within 20 kilometres of 10.9 degrees South 138.4 degrees East, estimated to be 230 kilometres northeast of Nhulunbuy and 425 kilometres west northwest of Weipa.

Movement: southeast at 24 kilometres per hour.

Tropical Cyclone Nora has reached Category 3 strength. Nora has started taking a more southeasterly track, heading into the Gulf of Carpentaria.

The system is continuing to instensify and is expected to reach Category 4 during Saturday while over the northeast Gulf of Carpentaria. On Sunday, the Tropical Cyclone is expected to take a more southerly track and move close to the southeastern Gulf of Carpentaria coast, although a coastal crossing anywhere along the western Cape York Peninsula south of Mapoon during Saturday or Sunday is also quite possible.

Hazards:

The risk of GALES, with gusts to 110 kilometres per hour, is easing for the Northern Territory, but may develop in coastal areas between Elcho Island and Cape Shield, including Nhulunbuy, for a period tonight before midnight.

GALES with gusts to 110 kilometres per hour may develop in coastal areas between Thursday Island and Pormpuraaw, including Weipa, early on Saturday. Gales may extend south between Pormpuraaw and Gilbert River Mouth later on Saturday, and between Gilbert River Mouth and the NT/Qld Border, including Mornington Island, overnight Saturday and during Sunday.

DESTRUCTIVE WINDS with gusts to 155 kilometres per hour may develop in coastal areas between Thursday Island and Aurukun, including Weipa, during Saturday if the Tropical Cyclone continues to track east southeasterly. Destructive winds may develop between Aurukun and Pormpuraaw later on Saturday or early Sunday. VERY DESTRUCTIVE winds with gusts to 270 kilometres per hour may develop between Mapoon and Pormpuraaw, including Weipa, during Saturday, if the cyclone does not begin to track more southerly on Saturday.

HEAVY RAINFALL is forecast about Torres Strait and Cape York Peninsula in the coming days and may extend to the Gulf Country of Queensland late Saturday and into Sunday, depending on the track of the Tropical Cyclone. Heavy rainfall could potentially lead to flash flooding in some areas.

As the cyclone approaches the coast, a storm tide is expected between Mapoon and Gilbert River Mouth. 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.

NTES advises communities between Elcho Island and Cape Shield, including Nhulunbuy:

– Prepare for gales and heavy rain during today and into this evening

– Finalise your home preparations

– Check your family, friends and neighbours understand and are prepared

– Move indoors and shelter as the conditions deteriorate

– Stay indoors and avoid travel during the storm

– Stay away from beaches and immediate coastal areas as dangerous coastal flooding may occur
