Explanatory Notes
A low pressure system centred to the south of Tasmania will move into the
Tasman Sea on Monday as a high pressure system develops well south of the
Bight. The high will extend a ridge across Victoria during Monday and Tuesday.
Another low pressure system will move into the Bight during Tuesday, gradually
moving eastwards to reach far western Victoria later on Wednesday before
crossing the State during Thursday.
