Emergency services across NSW are likely facing another busy day as parts of the state continue to cop a drenching.
Rains intensified overnight after some stations in northern NSW recorded more than 300mm within 48 hours.
A severe weather warning for very heavy rain, high winds, large waves and tides remains in place along the entire coast from the Northern Rivers region to the South Coast.
The wet weather has kept the State Emergency Service busy, with the organisation receiving more than 2600 calls for help across the state since midnight Wednesday.
Volunteers have responded to at least 20 flood rescues, mostly involving motorists who drove into floodwaters.
The SES last night urged residents across Sydney, the Illawarra and South Coast to prepare for heavy rain and potential flooding as a coastal trough causing rain and windy conditions continues moving south.
The Bureau of Meteorology also issued minor flood warnings for a number of catchments including the Cooks River, Orara River and Tuggerah Lake, and a minor to moderate warning for the Hawkesbury and Nepean rivers.
Wind warnings have been made for Sydney’s closed waters and coast, as well as the Macquarie, Hunter, Illawarra, Coffs, Batemans and Eden coasts on Sunday.
Further, a hazardous surf warning applies to the Macquarie, Hunter, Sydney, Illawarra, Batemans and Eden coasts on Sunday.
