High winds continue to hit Lord Howe Island as the remnants of ex-cyclone Uesi move south.
Uesi passed directly over the island in the Tasman Sea on Thursday night, bringing winds of up to 154km/h and leaving behind a trail of fallen trees, blocked roads and damaged buildings.
Bureau of Meteorology senior forecaster Jake Phillips says the worst of the storm has passed and will continue to ease on Friday night, with wind gusts peaking at 90 km/h.
Mr Phillips said 41mm of rain was recorded at the airport overnight.
"It's quite likely there was more but because of the high wind it is difficult for the rain gauges to catch a lot of it," he said on Friday.
Lord Howe Island board chief executive Peter Adams says the damage wasn't severe and no injuries were reported.
"We had all this extreme weather and then this eye of the storm calm," Mr Adams told AAP on Friday.
"It was quite eerie. You could hear the surf pounding the reef but the wind had calmed a bit."
Mr Adams says the island, home to almost 350 people, is set for a return to glorious weather over the weekend.
The storm is due to pass over Sydney's coast later on Friday and early Saturday, bringing dangerous surf conditions.
A hazardous surf warning is in place for much of the NSW coast on Friday and for the Hunter, Sydney, Illawarra, Batemans Bay and Eden on Saturday.
Surf Life Saving NSW warned rock fishers, boaters, surfers and swimmers to stay away from the water.
"If people don't heed emergency service warnings and put themselves in danger in these extreme conditions, it's possible that lifesavers will not be able to save them," lifesaving director Joel Wiseman said in a statement on Friday.
Some beaches may be closed on the weekend due to the large swell, poor water quality and large amounts of debris in the water.
Flood warnings are still in place across the state, particularly in the Perisher Valley, where 40mm was recorded between 2pm and 3pm.
Parts of NSW are facing more wet weather over the weekend after last week's deluge, particularly the bushfire-ravaged South Coast, the Southern Tablelands and western Sydney.
Mr Phillips said rain is likely to set in on Saturday afternoon but will be variable in some places due to thunderstorm activity.
The rain has brought much-needed relief for firefighters, with the NSW Rural Fire Service on Thursday confirming there were no uncontained fires for the first time this season.
There are currently 25 fires burning south of Sydney.
