Tropical low moving slowly south and expected to develop. Warning cancelled between Numbulwar and Port Roper.

Areas Affected:
Warning zone: Port Roper to Kowanyama, including Groote Eylandt, Borroloola, Mornington Island, and Karumba, and adjacent inland areas between Borroloola and Normanton.

Details of Tropical Low at 10:00 am AEST [9:30 am ACST]:
Intensity: Tropical Low (1000 hPa), sustained winds near the centre of 45 kilometres per hour with wind gusts to 85 kilometres per hour.
Location: within 55 kilometres of 14.4 degrees South 138.3 degrees East, estimated to be 195 kilometres east southeast of Groote Eylandt and 275 kilometres north northwest of Mornington Island.
Movement: south at 7 kilometres per hour.

The tropical low is currently moving slowly south over the Gulf of Carpentaria east of Groote Eylandt. During today, the southerly movement should accelerate, and meanwhile the system is expected to intensify and develop into a tropical cyclone tonight. Conditions for further intensification are favourable, and the system could still briefly reach category 2 prior to making landfall about the southern Gulf of Carpentaria coast between about Borroloola and Mornington Island on Monday morning.

GALES with gusts to 110 kilometres per hour may develop about coastal and island communities between Port Roper and Kowanyama, including Groote Eylandt, Mornington Island, Borroloola, Burketown, and Karumba, later tonight or early Monday morning. These GALES may extend further inland over the Northern Territory 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, including Bing Bong, early 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 coming days. Flood Watches are current for Gulf of Carpentaria catchments.
