Weather Situation

Northwesterly winds are expected to shift west to southwesterly during today and Wednesday as a cold front crosses the region. Winds along the southern waters may strengthen as a complex low pressure system, associated with the cold front, moves to the east of Tasmania. Following this, winds will slowly turn northeasterly by Friday, as the front and its associated low move towards New Zealand.
