A hiker missing for four days has been found safe after a massive search on the NSW South Coast.

Christopher Moore, 38, was dropped off to begin a camping trip in Jerrawangala, about 32km south of Nowra, at about 10.30am on Wednesday.

The alarm was raised when he failed to arrive at his pick-up location on Friday.

A search was launched by police in bushland around the Jerrawangala and Wandandian areas, where Moore was believed to have been camping, on Saturday.

The search has involved South Coast Police, Police Rescue, and members of the SES, Polair, and NSW Rural Fire Service and continued into Sunday, with no clues on Moore’s whereabouts.

The search resumed about 8.30am on Monday, and by 11.50am the man was found in dense bushland off Twelve Mile Road.

He was walked to safety by emergency services.

Paramedics assessed him at the scene and found no injuries, but he was taken to Shoalhaven Base Hospital for monitoring as a precaution.

There were earlier concerns the search could be hampered by a significant and potentially dangerous weather system forecast to impact the NSW coast on Tuesday.

Extensive strong damaging winds, possibly between 90km/h and 100km/h, could affect large parts of the east coast, particularly the Illawarra and mid-north coast.

Helicopters will generally not fly in wind conditions over 60km/h to 70km/h, depending on the helicopter model and pilot experience.

“We’re still working out the finer details of exactly which areas, and the finer points around timing and things like that, but certainly it is shaping up to be quite a significant weather system,” senior meteorologist Angus Hines said on the weekend.

Hines said the system will bring heavy and persistent rain over Tuesday and Wednesday, with early forecast models predicting 100mm to 200mm of rain in the space of a day or two.

A severe weather warning is expected to be issued by The Bureau of Meteorology on Monday morning.
