NSW SES Superintendent Scott McLennan says the worst of the rain is behind us as the cold front moves offshore over the next 24 hours. A further 18.8mm has fallen since 9am at Lismore Airport bringing the total rainfall since 3pm Thursday to 150.2mm.

Currently, the Wilsons River is a Flood Watch for minor to moderate flooding. However, the SES expects it to be changed to a Minor Flood Warning later this afternoon. At 12:44pm, the Wilsons at Lismore had risen to 2.06m, minor flooding occurs over 4.2m.

"The rain that has occurred overnight and into today, most of that's been absorbed; any further rain will actually now be run off, and that runoff will make its way into the rivers and creeks," Supt McLennan said.

For the NSW SES, the amount of jobs they have attended has increased as the cold front moved up the coast. Wind gusts have been recorded at 92 km/h at Evans Head.

"NSW SES volunteers and members have been attending approximately 180 to 190 jobs, with more jobs coming in today. Those incidents relate primarily to storm related incidences, including trees and branches as well as flooded causeways and culverts. We have had one flood rescue today, and that was a caravan that was in a causeway. This is a timely reminder: please do not drive through flood waters.

"Severe winds are still affecting the coast and will affect the coast well into tonight. The Wilson River at Lismore is expected to reach minor flooding tomorrow morning. Our focus, though, at the moment, is primarily the Coffs Coast and Bellingen regions. The Coffs Coast is a known flash flooding issue, and that area will occur sometime this afternoon and tonight.

"The heavy rainfall is starting to ease and will ease further into tonight, leaving us with riverine flooding throughout the rest of tomorrow."
