A SEVERE weather warning and total fire ban remains in place on the Coffs Coast today.
Some of the strongest gale force winds seen in NSW in recent years were recorded overnight in the south of the state.
Locally strong winds contributed to widespread black-outs and power outages across the Coffs Coast.
Northerly gusts of up to 60km/h are expected to prevail today with peak gusts further south of 100km/h.
The State Emergency Service answered 20 calls for help across NSW overnight.
It recommends people prepare for bad weather by securing all loose items around their properties, never parking cars under trees and ensuring that when the weather does hit, children and pets are indoors.
Roads and Maritime Services today also issued an alert following a Bureau of Meteorology warning about dangerous surf conditions for this afternoon and into tomorrow.
Three metre seas and one metres swells are forecast.
Skippers and owners of small craft should be on high alert and to check the conditions before considering crossing a coastal bar or heading offshore.
Dangerous surf conditions can easily translate into dangerous conditions for rock fishing and for vessels crossing coastal bars.
Strong winds can also mean dangerous conditions for vessels on moorings which have been poorly maintained.
A total ban fire remains in place on the North Coast again today.
On the fire front authorities are this morning seeking to contain two bush fires on the Coffs Coast.
Forests NSW now has a fire near Coffs Harbour under control that has burned out 50 hectares in the Wild Cattle Creek State Forest and along Orange Trees Rd.
A blaze in the Nambucca State Forest and along Hyland Park Rd is also being controlled.
It has burned out 59 hectares of scrub.
"Under these conditions, any fires, which do start have the potential to spread quickly and prove quite challenging for firefighters," RFS Commissioner Shane Fitzsimmons said.
The BOM says conditions have been caused by strong north to northwesterly airstreams ahead of an approaching cold front, tending more westerly and easing in the wake of the front on Thursday.
The next cold front is expected to bring strong to gale force west to southwesterly change along the NSW coast on Friday, particularly in the south.
A high pressure ridge should extend over the state over weekend.
