Weather Situation
A high pressure system will pass the south of Tasmania tonight, and reside over Tasman Sea on Sunday and Monday. The high centre is expected to weaken during Tuesday as a trough approaches the west coast slowly during the day, to cross Tasmania in the evening. The trough is then forecast to clear to the northeast during Wednesday while a new ridge of high pressure moves over Tasmania from the west.
