HEAVY rain today has heightened the region's swollen rivers and creeks as well as the fears of large-scale flooding.
A flood warning has been issued for Coffs Harbour as of 2.08pm.
If more heavy rain falls later this afternoon it could prompt concerns about high tides backing up floodwaters in Coffs Creek on Friday.
The city joins Bellingen, Bowraville, Nana Glen, Glenreagh and Nymboida on flood watch.
Those outlying centres have already experienced minor to moderate flooding
Major downpours have fallen in the catchment upstream of Coffs Harbour with 90mm recorded in the last six hours.
This is expected to cause minor flooding in low lying areas.
At 1:45 pm Coffs Creek stood at 2.64 metres and falling, but further rainfall is predicted for the next 12-24 hours, which could produce further river rises. The situation is being closely monitored.
Flooding is also unfolding this afternoon on the northern beaches.
Residents are being evacuated from low lying areas in Woolgoolga's Sunset Caravan Park, police report.
Rural Fire Service crews are also advising Corindi Park property owners not to return home until flood waters dissipate.
Police said cars have been also submerged in floodwaters on Eggins Dr between Arrawarra and Corindi Beach, near Darlington Park.
The roads authority has responded to metre deep flood waters, which are flowing across the Pacific Highway at Black Adder Creek north of Corindi.
A decision was made to close the highway north of Corindi in both directions at 2.11pm and traffic is starting to bank up at the scene.
North bound trucks are also queuing on the side of the highway in Coffs Harbour and Woolgoolga waiting on word for the roadway to clear.

Just how much rain has fallen and how quickly it has run-off into river systems has been evident in a plotted graph of the Bellinger River in flood.
In the latest update at 2pm, the Bureau of Meteorology has reported that up to 100 mm has fallen over the Bellinger catchment in the last six hours.
However the rainfall intensity has now eased and resulted in renewed river rises.
The Bellinger River at Thora peaked at 5.2 metres around 12pm with moderate flooding and there is currently moderate flooding at Bellingen.
At Thora the river remains near 5.2 metres with moderate flooding, while Bellingen will reach 7.6 metres around 3pm today with moderate flooding.
The SES advises that up to 400 mm has fallen over the Nambucca catchment over the past four days, with up to 30 mm occurring in the last six hours.
This has resulted in renewed rises in the Nambucca River and moderate flooding at Bowraville.
Further rainfall is forecast for the next 12 to 24 hours, which could produce further river rises.
