Weather Situation
An inland trough and developing low pressure system will move westwards over the next few days across southern and central WA, to be near the west coast on Sunday. Meanwhile, a cold front will brush past the southern districts on Friday, followed by a strong high pressure system developing south of the Bight on Saturday. As the high moves east on Monday, the low pressure system will slip into the Bight, with the trough moving inland again ahead of the next cold front arriving on Tuesday.
