BATTEN down the hatches because gale force winds are going to hit the North Coast this afternoon.
The Bureau of Meterology has this morning issued a severe weather warning.
Heavy swell up to 4-metres is also forecast.
Weather Situation: A deepening low pressure system over the central Tasman Sea combined with a strengthening high pressure ridge in the east of the state is generating vigorous southerly winds along the New South Wales coast.
Damaging Winds: Averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are likely over parts of the Illawarra, Sydney and Hunter coastal fringe from the afternoon, and over the far northern coastal fringe from the late afternoon.
Winds are expected to ease overnight.
Locations which may be affected include Coffs Harbour, Newcastle, The Entrance, the Sydney coast, Wollongong, Jervis Bay, Yamba and Byron Bay.
