DAMAGING WINDS AND SURF ACROSS THE COAST FOR SATURDAY.

Weather Situation: A low pressure system currently in the southern Tasman Sea is expected to deepen Saturday producing a surge of southerly winds around its western flank. This surge of winds will increase the risk of damaging winds about the coastline, in addition to large, powerful and damaging surf conditions.

DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are possible from early Saturday morning along the south coast, shifting up the coastline into Saturday afternoon and evening. Wind gusts are likely to associated with showers and thunderstorms pushing over the coastal fringe.

Winds are expected to ease below the damaging criterion from the south of the warning area by later Saturday afternoon, before easing throughout by Saturday evening.

VERY HEAVY SURF which may lead to localised damage and coastal erosion is possible for beaches south of Seal Rocks. Beaches at highest risk will be those orientated south to southeast.

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

A hazardous surf warning has also been issued for Saturday for the coastline south of Coffs Harbour.

Locations which may be affected include Newcastle, Gosford, Sydney, Wollongong, Nowra and Batemans Bay.

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.
* Trees that have been damaged by fire are likely to be more unstable and more likely to fall.
* Report fallen power lines to either Ausgrid (131 388), Endeavour Energy (131 003), Essential Energy (132 080) or Evoenergy (131 093) as shown on your power bill.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
