Weather Situation
A low pressure system near Tasmania is slow-moving, with its associated cold front and trough crossing the southern and central coastal waters and bringing a west to southwesterly wind change in their wake. Winds will then gradually ease and become light and variable later in the week as the low heads to the Tasman Sea and weakens, while a high pressure system moves across the state.
