THURSDAY 1PM: SURF Life Saving NSW is urging all coastal water users to remain vigilant following the issuing of a dangerous surf warning by the Bureau of Meteorology.
The heavy swells, strong coastal winds and widespread rain expected are caused by the presence of Tropical Cyclone Marcia off the Queensland Coast.
Heavy conditions are expected from Friday and look set to continue through to Sunday night.
Swells with peaks of up to 4 metres are expected between the Queensland Border and Smoky Cape on the state's Mid-North-Coast propelled by East to North-Easterly winds. Some beaches may be closed due to hazardous conditions.
The warning is in place for the entire NSW coastline with conditions further south also expected to be heavy with swells anticipated to be between 2-3 metres and have swell periods of up to 10 seconds.
Extra care should be taken by boat skippers crossing coastal bars, rockfishers, swimmers and surfers.
"While the heaviest swells and unpleasant conditions are likely to be concentrated around the northern part of the state, we would still encourage all coastal users to be vigilant for their own and others safety," Surf Life Saving NSW Operations Manager Adam Weir said.
"Know your limits, talk to the locals, and if in any doubt about the conditions, don't go out."
Conditions have been forecast to ease slightly by Monday.
THURSDAY 9AM: A trough associated with Tropical Cyclone Marcia over the Coral Sea is expected to deepen over the northeast of New South Wales later today and tomorrow.
Rain which may lead to flash flooding is forecast for the Northern Rivers forecast district, in addition to northern parts of the Mid North Coast and eastern parts of the Northern Tablelands forecast districts during Friday.
At the time of issue a Flood Watch was current for the New South Wales coast from the Queensland border to the Nambucca Valley for Friday and Saturday.
Unusually high ocean temperatures in the order of 27 degrees off the North Coast are expected to add to the strength of the system.
The bureau says there is a greater than 70% chance of flooding between the Nambucca Valley and the Queensland border.

WEDNESDAY 1PM: FLOOD watch advisories have been issued for a number of rivers on the North Coast for Friday and Saturday, as meteorolgists track the developing tropical low.
The Bureau of Meteorology this afternoon said there is some uncertainty over the forecast rain totals for this event as it depends upon the eventual severity of the tropical low that is currently located over the Coral Sea.
In addition, king high tides will add to the risk of flooding in the lower tidal reaches of these rivers.

- Bellinger Valley
- Nambucca Valley
- Clarence Valley including the Orara River
- Richmond and Wilsons Valleys
- Brunswick Valley - including Billinudgel
- Tweed Valley - including local flash flooding is areas such as Chillingham
