Details of Tropical Low 30U at 9:30 am ACST:
Intensity: tropical low, sustained winds near the centre of 55 kilometres per hour with wind gusts to 85 kilometres per hour.
Location: within 55 kilometres of 12.2 degrees South, 138.5 degrees East , 185 kilometres east of Nhulunbuy and 295 kilometres northeast of Alyangula .
Movement: west at 16 kilometres per hour .
Tropical Low 30U is expected to continue to move westwards across the Gulf of Carpentaria today. There remains a low risk it will develop into a tropical cyclone, but it is more likely to remain a tropical low. Gales are forecast to develop on the southern side of the system later today.
30U will pass close to the northeast Top End coast later today, and a Severe Weather Warning is current for damaging winds and heavy rainfall in that area. For details see http://www.bom.gov.au/nt/warnings/
On Tuesday, 30U is likely to move northwest into the Arafura Sea, where it should persist and be slow moving for most of the week.
