Weather Situation
A strong high pressure system over southern WA is slowly moving east and will exit the state later tonight. A west coast trough will form on Monday as a weak cold front brushes past the southwest coast. A cloud band will develop over central and southern WA on Tuesday, with the west coast trough moving inland on Wednesday ahead of a second cold front.
