Please be aware
Wind and wave forecasts are averages. Wind gusts can be 40 per cent stronger than the forecast, and stronger still in squalls and thunderstorms. Maximum waves can be twice the forecast height.
A series of cold fronts are forecast to pass over the state in a persistent west to southwesterly flow on the eastern flank of a high pressure system to the west. The flow will ease later this week as the high pressure system moves closer to Tasmania and extends a ridge over the state on Friday. The ridge is expected to move southeast at the weekend.
