Weather Situation
A strong westerly flow will gradually ease during today before a low pressure system approaches from the west early Saturday. This low is expected to cross southern Tasmania on Saturday, bringing a series of troughs and a cold front over the state. A west to southwesterly airstream is expected to follow the low with a weak cold front crossing the state early Monday before a ridge of high pressure develops from the west.
