The week’s inclement weather was the result of two separate air masses interacting to give rain, strong winds and big seas along our coastline. An upper level trough approaching from the north-west was the driving force behind the periods of heavy rain. As this trough line slowly moved seaward cells of east coast lows developed off-shore to bring more rain and whip up the surf still further. The steep pressure gradient between the fringes of the high in the Tasman Sea and the east coast lows was responsible for the strong winds experienced in some areas.
