View the current warnings for New South Wales

Forecast issued at 4:08 pm EDT on Saturday 23 January 2021.

Weather Situation

A high pressure system over the Tasman Sea extends a ridge to the northern New south Wales coast, while a weak trough lies over southern waters. This trough will decay tonight, although a new trough is forecast to briefly affect the south later Sunday. The high is expected to remain dominant in the region until Tuesday, when it looks set to weaken and allow a stronger trough to move through southern and central waters.
