For people in parts of Mid North Coast, Hunter, Metropolitan and Illawarra Forecast Districts.

Issued at 11:05 am Saturday, 2 June 2018.

A low pressure system over the Tasman Sea is generating vigorous southerly winds with large and powerful waves.
VERY HEAVY SURF is likely to cause localised damage and coastal erosion for some exposed, south-facing zones along parts of the coast, between South West Rocks and Ulladulla.

Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas.

DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h, are possible with showers along the coastal fringe between South West Rocks and Ulladulla during Saturday.

Conditions are expected to ease in the late afternoon and evening on Saturday as the low moves further away to the east.
Locations which may be affected include Port Macquarie, Newcastle, Sydney, Wollongong, Nowra and Ulladulla.

The State Emergency Service advises that people should:
* Move vehicles under cover or away from trees.
* Secure or put away loose items around your house, yard and balcony.
* Keep at least 8 metres away from fallen power lines or objects that may be energised, such as fences.
