ABNORMALLY HIGH TIDES AND DAMAGING WIND DURING FRIDAY AND SATURDAY FOR THE NORTH COAST.
At 11 am AEST this morning, tropical cyclone Oma was in the eastern Coral Sea, approximately 890 kilometres northeast of Brisbane. Tropical cyclone Oma is forecast to move to the southwest over the next few days, and will generate a significant east to northeasterly swell over far northern New South Wales beaches. The increasing swell is also expected to combine with king tides.
ABNORMALLY HIGH TIDES which may cause sea water flooding of low lying areas are possible north of Yamba on Friday and Saturday.
Water levels on Friday and Saturday at high tide may exceed the highest tide of the year by around half a metre. The approach of Tropical Cyclone OMA may see additional sea level rises during Saturday.
Hazardous surf conditions are also forecast over the northern New South Wales coast today and on Friday, extending to central parts of the coast over the weekend.
Locally damaging wind gusts in excess of 90 kilometres per hour may develop about the exposed coast near the Queensland border during Friday and into Saturday. These damaging wind gusts may extend to the northern border ranges later on Friday. A Tropical Cyclone Watch is also current for areas between Bundaberg and Ballina (NSW).
Locations which may be affected include Tweed Heads, Hastings Point, Byron Bay, Ballina, Yamba and Brunswick Heads.
