FLOODING POSSIBLE IN PARTS OF THE BONAPARTE AND NORTH WEST COASTAL RIVERS FROM SUNDAY A monsoon trough is developing across northern Australia, with a low (30U) developing on Monday inland of the Joseph Bonaparte Gulf, then moving slowly towards the west coast. Catchments in the flood watch area are wet from recent rainfall. Showers and thunderstorms will be more frequent about the trough, with some heavy falls possible. Rainfall may cause significant water level rises in rivers and creeks and prolonged overland flooding and ponding from Sunday and roads may become impassable. Some communities and homesteads may become isolated. Check road conditions before travelling.
