- Weather Situation
- A low pressure system is approaching Tasmania from the west and will pass close to the south during Sunday. A cold front associated with the low will cross Sunday morning with a cool west to southwesterly airstream to follow which will persist into Monday. Later Monday, a large and significant low pressure system is expected to move over the Bight and approach Tasmania, extending a warm front over the state early Tuesday. The low complex then moves over Tasmanian and remains in the vicinity throughout Wednesday.
