Weather Situation
A high pressure system near the NSW coast moves slowly east over the Tasman Sea bringing southeasterly winds to the northern part of the coast and light and variable winds to southern and central parts of the coast. Winds will tend north to northwesterly over the coming days as the high moves further east before a strong cold front enters coastal waters from the west mid-Tuesday.
