Weather Situation
A strong ridge over southern WA brings moderate to fresh southeasterly winds, and the strength of the offshore gradient will result in minimal sea breeze activity through to Saturday. A new trough will start to deepen down the west coast from Sunday, causing the offshore gradient to ease somewhat with sea breezes returning to coastal parts.
