Sydney is due one more lashing from the powerful low-pressure system hovering off the NSW coast that earlier caused flooding in regions south of the city and triggered the closure of a primary school.
The NSW State Emergency Services carried out three rescues in the Sanctuary point area in the basin Tuesday afternoon as floodwaters rose.
Sydney escaped with little rain on Tuesday after an intense thunderstorm pelted the city with a heavy downpour and hail on Monday night.
The low-pressure system was expected to move further north again on Tuesday evening, bringing gale-force winds to coastal areas.
The Bureau of Meteorology has issued a marine wind warning, which includes an alert for strong winds on Wednesday for Sydney coastal and harbour waters, and the Eden and Hunter coasts.
The shifting low is expected to direct southerly winds over Sydney on Wednesday, with showers easing during the day, the bureau said.
The outlook for Sydney and most of NSW is for much more benign conditions in coming days.
The city is expecting six millimetres of rain at the most on Wednesday and then only possible showers until early next week.
Overnight temperatures will remain mild due to cloud cover, although the mercury may dip to single digits again on Sunday and Monday.
Maximum temperatures will also remain subdued during the partly cloudy days, with tops of 19-21 degrees until Tuesday, when the start of spring may bring a maximum of 23 degrees, the bureau predicts.
