Weather Situation
A high pressure system over the Tasman Sea is directing northerly flow over Victoria, with a trough sitting over western coastal waters which will move east early this morning. A cold front will approach the State from the west and cross Bass Strait during the day today before the next high builds over the Bight and extends a ridge over Victorian coastal waters on Monday. That high moves into the Tasman Sea on Tuesday.
