View the current warnings for New South Wales

Forecast issued at 4:05 pm EDT on Tuesday 27 October 2020.

Weather Situation

A strong high pressure system south of Tasmania is slowly moving east, while a low pressure system over the Tasman Sea extends a trough towards the Queensland coast. This pattern will maintain south to southeasterly winds and a southeasterly swell over New South Wales waters for the next day or two. On Thursday, the coastal trough may deepen and strengthen southerly winds as a transient low pressure system forms and moves away to the east. After this, winds are expected to turn east to northeasterly and increase as a new trough develops over inland New South Wales.
