Strong high pressure support from a 1033hPa elongated high in the Bight is providing tight pressure gradients for the multiple fronts spinning off the gyre. That will lead to numerous over-lapping S’ly pulses over the coming week with a general step-ladder effect expected at least through to Mon. A general offshore flow will accompany these pulses as the fronts drive W’ly biased winds across the temperate to sub-tropical East Coast.

Extended round of S swell pulses ahead, sizey over the weekend

A strong node of the long wave trough is steering fronts into the Tasman Sea while a negative phase of the SAM (Southern Annular Mode) is bringing the southern Ocean storm track into a more northerly latitude, closer to the Australian continent and Tasman Sea. Both those factors will drive a series of strong cold fronts this week, with a step-ladder effect likely as each subsequent front works on an already charged sea state.
