Wild rain, wind tipped to lash Tasmania

Tasmanians have been warned to brace for possible flooding and wild weather as a cold front sweeps across southern Australia.

Heavy rain is forecast in southern and eastern parts of the state on Thursday and Friday, the Bureau of Meteorology says.

Two-day localised falls of up to 150mm are possible.

SES crews are on stand-by across the state, with a flood watch warning in place for the eastern half of the island.

"Flooding in streams and rivers is likely during the next few days," SES assistant director Leon Smith said.

"Some low lying properties may become isolated by flood waters.

"People should prepare themselves by moving livestock and equipment to higher ground if possible."

Gale force winds are also expected late on Thursday and into Friday.
