Weather Situation
A high pressure system east of Tasmania maintains a ridge across eastern waters, ahead of a weak cold front moving across the Bight today and the southeastern coastal waters on Friday. Another high will extend a ridge over SA late Friday before becoming established over the state on Saturday, as another weak cold front clips the southeast. The high will continue to move southeastwards on Sunday towards Tasmania, as another front approaches from the west.
