Careys Peak in the Barrington Tops National Park recorded 143mm in the 24 hours before 9am this morning, outdoing heavy rainfall in the Sydney Metro and Lower Hunter regions, where much of the weather system was concentrated.

Stroud received the most rain out of any township in the Mid Coast LGA, recording 50mm, while closer to the coast the recorded figures were considerably less.

Taree recorded 3.6mm on Tuesday and 3.6mm on Wednesday, bringing the total for this monthy to 11.2mm.

Bulahdelah recorded 4mm, Bungwahl 5mm, Nabiac 7.5mm, Forster 1.6mm and Tuncurry 2.5mm.

This stood in stark contrast to the rainfall received further down the coast, where Nelson Bay recorded 72mm and a flood watch was put in place for parts of the Lower Hunter and Central Coast.

A spokesperson from the Bureau of Meteorology said the positioning of the low pressure trough causing the downfalls meant the rain was highly concentrated in certain areas.

Rain has fallen in the Mid Coast today since 9am and was predicted to continue into the afternoon, but it was not expected to exceed 5-10mm.

"Most land-based rainfall is around Port Stephens and further south," the BOM spokesperson said.

There was the possibility of showers through until Friday but nothing significant, they added.
