Issued at 10:51 pm EST on Sunday 23 February 2020

Tropical low moving south towards Mornington Island. Expected to develop into a tropical cyclone overnight.

Areas Affected:
Warning zone: Port Roper to Kowanyama, including Borroloola and Mornington Island and adjacent inland areas between Cape Crawford and Century Mine, including Doomadgee.

Watch zone: Inland areas between Limmen National Park and Brunette Downs.

Cancelled zone: None.

Details of Tropical Low at 10:00 pm AEST [9:30 pm ACST]:
Intensity: Tropical Low (994 hPa), sustained winds near the centre of 55 kilometres per hour with wind gusts to 85 kilometres per hour.
Location: within 35 kilometres of 15.3 degrees South 139.1 degrees East, estimated to be 155 kilometres north of Mornington Island and 310 kilometres east northeast of Borroloola.
Movement: south southeast at 11 kilometres per hour.

The tropical low is expected to continue moving southward and develop into a tropical cyclone overnight. Conditions for further intensification remain favourable, and the system could briefly reach category 2 prior to making landfall about the southern Gulf of Carpentaria coast between about Borroloola and Mornington Island on Monday.

GALES with gusts to 110 kilometres per hour are expected to develop about coastal and island communities between Port Roper and Kowanyama, including Mornington Island, Borroloola, Burketown, and Karumba, later tonight or early Monday morning. These GALES may extend further inland over the Northern Territory and far northwest Queensland later on Monday as the system moves inland.

DESTRUCTIVE winds with gusts to 130 kilometres per hour are possible in coastal areas between about Borroloola and Mornington Island on Monday as the system approaches.

A STORM TIDE between Port McArthur and Karumba is expected as the cyclone centre crosses the coast. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING between Port McArthur and Karumba. ABNORMALLY HIGH TIDES are expected to develop about the southwestern Gulf of Carpentaria coast over the next couple of days. Large waves may produce at least MINOR FLOODING along low-lying coastal areas. 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 RAIN with the potential to cause flash flooding is expected in areas around the Gulf of Carpentaria over the next couple of days, then move west following the low over the coming days. Flood Watches are current for Gulf of Carpentaria catchments.
