The front will cross Bass Strait on Saturday afternoon and evening as the next high pressure system crosses South Australia. The high will then cross Victoria on Sunday before moving over the Tasman Sea on Monday as the next cold front approaches from the west. This front will also weaken as it crosses Victoria and Bass Strait on Tuesday.
