A deep low pressure system near Tasmania is directing strong southerly winds across the South Oz coast.

The onshore pattern remains established over the weekend with high pressure riding at sub-tropical latitudes and a zone of enhanced storminess riding NE with seas in excess of 25ft later this week. 

We have a deep low (985hPa) adjacent to Tasmania and another attached low centre further E in the Tasman with the long E’ly infeed into this complex low gyre focussed near the west coast of the North Island aimed up at Tasmania.
