The current synoptic pattern is a low pressure system E of Tasmania directing a fetch of SSW to S strong winds to low end gales adjacent to the NSW South Coast. This low then eases as it moves out into the Tasman sea later today.

Freshening SW winds this afternoon are related to a weak front crossing the coast. They’ll strengthen overnight and hold through Saturday before veering S/SE on Sunday and starting to ease back a bit.

Next week still looks like being marred by a constant onshore flow until Thursday as a node of the long wave trough directs weak fronts into the SW.

The current Tasman low has drifted out and become absorbed into a long, NE/SW angled trough in the South Pacific, which is currently organising and energising a broad but thin fetch of E’ly gales from the South Pacific down into the Tasman Sea adjacent to the North Island.
