Weather Situation
A high pressure system over Tasmania will gradually drift eastwards while a weak coastal trough lingers off the New South Wales coast, maintaining south to southeasterly winds over the coastal waters for much of the period. Winds will tend north to northeasterly by early next week as the high enters the Tasman Sea and moves further east.
