Weather Situation
A broad low pressure system developing across northern Victoria will slowly drift southeastward on Saturday with a series of associated troughs moving over the state. This low is expected to move into eastern Bass Strait by the early hours of Sunday then out to the Tasman Sea by Monday as a weak high pressure system extends over the State from the west. The high will clear as a cold front crosses Bass Strait on Tuesday.
