A trough brings a S’ly change tomorrow , with another strong high tracking south of the Bight poised to be the main weather feature this week.

Another huge swathe of severe gales pushing of Japan Tues/Wed tracks towards Hawaii with a captured fetch , generating another large/XL swell Fri with size pushing up into the 15ft range, with light SE winds expected as the edge of the windfield sweeps past the island and a weak high pressure ridge builds in behind it.

The slowed movement and enlargement of the wind field as it approaches the North Island are on track to deliver more powerful long period E-E/NE swell, not ideally aimed for Tasmania but with enough strength to deliver some 3-4ft sets through Mon and Tues.

There's been an upgrade in one of the storms generating Sunday's reinforcing swells.
