Rivers still on flood watch

ALTHOUGH more rain fell in Coffs Harbour on Tuesday night than the river catchment areas, a close eye is still being kept on the Orara and Bellinger Rivers.

The Bureau of Meteorology still has flood watches current but the recent rain has not seen those watches escalate to warnings.

A deepening low pressure trough off NSW north coast and an upper cold pool is expected to bring heavy rain locally with a chance of thunderstorms.

Further showers are expected on Thursday and Friday.

With this in mind the Bureau has predicted that there's greater than a 70% chance of some minor flooding developing in the Orara and Bellinger river valleys.

Weather Channel Meteorologist Tom Saunders said the rest of the week would see periods of heavy rain continue to linger around the area.

"Almost the entire NSW coast- line can expect over 100mm of rain by Saturday while some beaches from the Illawarra to Mid North Coast are forecast to see 200mm," Mr Saunders said.

"The rain should ease on Friday as the trough moves out into the Tasman Sea."
