ISOLATED MINOR FLOODING POSSIBLE IN THE FLOOD WATCH AREA FROM THURSDAY ONWARDS

A trough is expected to develop off the south coast during Wednesday and deepen into a coastal low during Thursday, which is likely to bring heavy rainfall and flooding across the southern parts of the central coast, Illawarra, northern parts of the south coast and the adjacent ranges. Abnormally high tides will also impact the low lying areas along the NSW coast.
