A cold front and its associated trough are forecast to cross the coastal waters late Wednesday into early Thursday, with fresh westerly winds turning southwesterly in their wake. Then, a high pressure system moving over South Australia is expected to drift towards Tasmania later in the week through the weekend, directing onshore south to southeasterly winds over the coastal waters.
