Never-ending rain to continue over weekend
Strong winds, big waves to accompany rain

Aussies are being urged to hunker down this weekend as a 'dynamic' low pressure system brings rain, powerful wind and large waves to millions.

The system is expected to cause non-stop rain and powerful onshore winds in eastern, central and northern NSW from Friday into the weekend.

The Bureau of Meteorology's Miriam Bradbury told Weekend Today on Saturday the system was currently sitting off the North Coast of NSW.

A severe weather warning has been issued for the Mid North Coast, Hunter North West Slopes and Plains, Northern Tablelands and Central Tablelands Forecast Districts, all areas in the firing line of the system.

The heaviest falls will drench central and northern NSW where falls of 30mm to 60mm are likely, with more than 100mm likely in some areas.

Heavy rainfall could lead to flash flooding in inland parts of the Hunter, Mid North Coast and Northern Tablelands from Saturday afternoon.

Large parts of NSW will be battered by 90km/hour winds with southeasterly gusts to cause havoc in central and eastern parts of the state on Saturday.

Engineers were later seen at the site, which has a large exclusion zone in place.

The Harbour City experienced even more heavy rain overnight, with some areas drenched with between 30mm and 50mm.

Conditions will ease by Sunday afternoon as the system moves off the NSW coast.

Coastal areas of NSW and southern Queensland will be impacted by large waves as onshore winds strengthen over the weekend.

Snow is forecast for elevated areas of northern NSW on Saturday with a chance of a 'few snow flurries' in southern parts of Queensland, Weatherzone said.

'Although the cold air might pass too far west of the state’s Darling Downs to facilitate snow north of the NSW border,' it said.
