Weather Situation
Northerly winds will turn southerly from the south today through Monday as a cold front brushes the coast. Fresh northerly winds will develop later Tuesday as a ridge extends to the Tasman Sea and a high pressure system forms within it. Then, the next trough brushing the southern and central parts of the coast mid to late this week will bring another south to southeasterly wind change in its wake.
