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. As the high enters the Tasman Sea and moves further east, winds will tend north to northeasterly from late today to early next week.
