The Bureau of Meteorology has warned of damaging surf and abnormally high tides along the Mid North Coast.
A low pressure system over the Tasman Sea is deepening in response to a cold front.
This low is generating vigorous southerly winds with large and powerful waves.
The bureau says 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. Conditions are expected to ease during Saturday as the low moves further away to the east.
Abnormally high tides may cause sea water flooding of low lying areas along central parts of the coast during the high tide on Friday night. Water levels could exceed the highest tide of the year by 0.5 metres.
The bureau issued a hazard surf warning for our coast on Thursday.
The State Emergency Service advises that people should:
- Don't drive, ride or walk through flood water.
- For emergency help in floods and storms, ring your local SES Unit on 132 500.
