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 trough extending from the Gascoyne to the Goldfields will gradually move westwards across the South West Land Division to be located near the west coast by the weekend where it is expected to deepen. The trough will move offshore on Sunday as a high pressure system moves into the Bight and strengthens.
