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 ridge over southern WA will weaken and move east, allowing a deep west coast trough to move further inland later today. A weak cold front will pass through the Bight on Saturday, followed by a new ridge developing over southwest WA. The ridge will extend over southern WA on the weekend, shifting the inland trough to the Gascoyne.
