Details of Tropical Low at 5:00 am AWST:
Intensity: tropical low, sustained winds near the centre of 45 kilometres per hour with wind gusts to 85 kilometres per hour.
Location: within 35 kilometres of 16.6 degrees South, 122.7 degrees East , 160 kilometres north northeast of Broome and 35 kilometres southwest of Cape Leveque.
Movement: southwest at 11 kilometres per hour .
A tropical low lies just to the south of Cape Leveque, and may continue to develop near the west Kimberley coast during Wednesday. Squally winds and heavy rainfall are likely over the west Kimberley during Wednesday and Thursday as the low tracks in a southwesterly direction, roughly parallel to the coast. The low could reach tropical cyclone strength Thursday morning if it remains offshore. There is a slight chance the low moves over land and fails to reach tropical cyclone intensity. If the low does develop it is likely to make landfall somewhere between Broome and Port Hedland later on Thursday.
