Weather Situation
A cold front continues moving east over the Tasman Sea, directing a cold west to southwesterly airstream over the state. Winds begin to ease today as a high pressure system moves into the Bight, directing a ridge of high pressure over northern Victoria into early next week, while a mostly westerly flow continues in the south. Another cold front is expected to enter Victoria early Wednesday, briefly weakening the ridge of high pressure.
