Weather Situation – Northern Western Australia
A ridge that extends through most of northern WA will weaken during the next
couple of days. The northern end of a trough will push eastward across the
Pilbara on Wednesday and Thursday, with a ridge strengthening it its wake.

Weather Situation – Southern and Central Western Australia
A high is moving into the Bight as its associated ridge weakens over southern

will strengthen from the west in the wake of the trough as a cold front and low
pressure system through the Southern Ocean bring increasing winds about the
southern districts late in the week.
