Weather Situation – Northern Western Australia
A surface trough lies over the western Pilbara. A strong high pressure system over southeastern Australia is directing an easterly flow over remaining northern parts. The high will weaken and contract east later on Saturday allowing a surface trough will develop over the west Kimberley and Pilbara.

Weather Situation – Southern and Central Western Australia
A surface trough lies across the Gascoyne, Goldfields and Eucla and a weak ridge of high pressure extends over the south west of the State. A middle level cloud band streaming over the south west corner of WA will persist before weakening later on Saturday. The ridge of high pressure will eventually migrate and build to the south of the State on Sunday, pushing the surface trough north and eastwards into the Interior.
