'Abnormally' high tides, huge swell as cyclone approaches

UPDATE 6.50am: AT 11 PM last night, tropical cyclone Oma was in the eastern Coral Sea, approximately 990 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 Ballina on Friday.

Water levels on Friday's morning high tide may exceed the highest tide of the year by around half a metre.

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.

Locations which may be affected include Byron Bay, Ballina, Brunswick Heads, Tweed Heads and Hastings Point.


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.
