Weather Situation
A cold front lies east of Tasmania late Friday directing a strong west to southwesterly flow over the State. A high pressure system south of the Bight slowly builds a ridge over Tasmania in the wake of the front during Thursday and Friday. The high will then move to the south of Tasmania on Saturday before entering the Tasman Sea on Sunday.
