An incredibly strong high pressure cell (1043 hPa) near New Zealand is driving an impressive tradewind fetch through the North Island/South Pacific corridor , as well as local onshore winds through the Coral and Northern Tasman sea.

By Mon morning the Tasman sea will be inflamed with severe gale to potentially storm force winds, as a robust low and reinforcing cold front push into the lower Tasman.

A S'ly change will move in mid-late morning tomorrow as a new W/SW groundswell builds. Cleaner conditions and a strong swell is due early-mid next week.

Initially, winds on the Western (East Coast Aus) side of the Tasman begin to freshen from the North and we’ll see that through the rest of the working week as the high pressure ridge gets squeezed by an approaching trough and front.
