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 broad trough extends from the Gascoyne to the South East Coastal district, gradually moving eastwards. A ridge will nudge into western parts in the wake of the trough, strengthening over central WA this weekend. The combination of the ridge and a low pressure system developing the Southern Ocean will result in increased winds over southern waters from Friday.
