Weather Situation
A trough is moving eastward through the inland South West Land Division as an Indian Ocean high extends a new ridge across the west coast. The ridge will strengthen in earnest during tonight and Tuesday, resulting in a strong southerly surge. Winds will tend more southeast to easterly from Wednesday as the high moves eastward to be south of the State by Friday.
