View the current warnings for New South Wales

Forecast issued at 11:47 am EST on Wednesday 17 September 2014.

Weather Situation

A relatively weak low pressure system over the southern Tasman Sea extends a trough northwards off the NSW coast. The low is expected to move slowly to the southeast and intensify during Wednesday while a cold front moves northeast from the Southern Ocean clipping far southeast NSW later in the day. Fresh to strong southwest winds are expected for southern and central waters on this day. Another cold front or trough is likely to pass near southeast NSW on Thursday and Friday, and combined with a slow moving high south of Adelaide, is likely to bring fresh to strong southwest to southerly winds to the southern half of the coast. A southerly swell is also expected to increase late in the week.
