Meteorologist with weatherzone Ben McBurney says the rainfall is being driven by a complex low system currently sitting around the Mid-North Coast.

"Sunday will see a lessening chance of showers after the area received a real drenching overnight on Saturday," he said.

"This is the heaviest rainfall recorded since March with 43mm falling in the 24 hours since 9am on Saturday.

"There will be the continuing chance of rainfall on Sunday and Monday, but that is only a slight possibility.

"Temperature-wise Sunday should be reasonably warm at around 22 degrees while Monday will drop to about 18 degrees. While there is the chance of some falls in the area it should not be too heavy at all," he said.

As the low continues in a southward direction, winds on Sunday will continue to drop although they did reach around 30 kilometres per hour on Saturday night.

Sunday will see off-shore winds that are light to moderate in strength although probably becoming gustier and in a westerly direction on Monday.

"In terms of the next couple of days, the situation will get a bit more complex," Mr McBurney said.

"We should see another burst of showers moving into the area on Tuesday, Wednesday and Thursday and even Friday.

"These should be moderate to heavy falls through Port Macquarie and the broader Mid-North Coast region.

"We could see falls in that period between 20 to 40mm until at least Thursday."

Rainfall figures from the region include, Port Macquarie dam 22mm, Port Macquarie Golf Club 35mm, Port Macquarie Airport 43mm, Wauchope (Bain Street) 32mm, Koree Island 33mm, Telegraph Point 41mm and Mt Seaview 58mm.

Despite the heavy rainfall, emergency services crews received only a few calls with State Emergency Services attending two incidents, one with tiles damaged on a house and one small tree falling on McLaren Drive with crews mopping up the area in a few hours.
