The Bureau of Meteorology (BOM) has issued a severe weather warning for a 1000km stretch of the NSW east coast for the next 24 hours.
The warning has been issued for the coast all the way from Eden on the south coast to Kempsey.
A front is crossing the state and is expected to deepen into a low-pressure system late today.
A trough associated with the low will sweep from south to north during Tuesday that will generate vigorous southerly winds and dangerous surf along the NSW coastline.
Surf Life Saving NSW CEO Steven Pearce urges the public to take extreme caution if they are visiting the coast.
"It's crucial for anyone visiting the coast to consider the risks associated with these conditions before putting themselves, their family and our lifeguards in danger," he said.
Damaging winds up to 70km/h with gusts over 90km/h are expected to hit the coast later today and throughout tomorrow. These wind gusts are expected to reach the Mid North Coast by early tomorrow afternoon.
Heavy surf, over five metres in parts, could cause damage and erosion as the system moves north.
Locations which may be affected include the Mid North Coast, Gosford, Sydney, Wollongong, Nowra and Batemans Bay.
