Weather Situation
A broad trough of low pressure lies over Victoria and Bass Strait and is expected to linger over the area this evening. A low pressure system south of the Bight will move east and combine with this trough over western Victoria early Sunday. The low pressure system will then deepen and slowly move south east across the State during Sunday to clear into eastern Bass Strait late Sunday. A high pressure ridge then builds across Victoria and Bass Strait during Monday. A weak cold front crosses Bass Strait during late Monday and early Tuesday with the ridge re-establishing itself from Tuesday to Thursday.
