The deeper southern fetch tied to the polar low then fires up and aggressively tracks almost due north towards Tasmania with gales and severe gales extending up to almost Tasmanian latitudes later Mon.

This is another impressively large and complex system, with a double headed low centre forming in the deep southern ocean around 60S and a more proximate cold front fetch expected to push NE to be adjacent to Tasmania through Monday morning.

With severe gales extending from Tasmania down to 55S and a slightly more favourable SSW tilt in the winds which then push up adjacent to SE Tasmania during Tues..

The result is a long, broad fetch of severe gales from 55S up to Tasmanian latitudes Sun , extending even further south late Sun into Mon with a more favourable SSW tilt in wind alignment in the fetch.
