UPDATE: A WOMAN was winched to safety by the air ambulance in Middle Tarwin, in Gippsland, this morning after her car stalled in flood water.

A Victoria Police spokeswoman said the 60-year-old from Sandy Point was driving on Buffalo-Tarwin Lower Rd when she attempted to drive through about 300m of flood water.

She became trapped after her car stalled in 1m deep water just after 9am.

The water is believed to have been about three-quarters the way up the cars' doors.

"She is fine, apart from being cold, wet and severely embarrassed,” the police spokeswoman said.

An Ambulance Victoria spokesman said the air ambulance from Morwell attended and MICA paramedics winched her to safety.

"One of the MICA paramedics were on the bank, I suppose you would call it, comforting her," he said.

The ambulance team noted there was about 100m of water either side of the car.

The Victorian SES today warned motorists not to drive through flood water because it could take just 60cm to float a car.

A SES spokeswoman said volunteers had responded to more than 350 vehicle rescues after drivers tried to drive through flood water this year alone.

She said motorists driving through flood water was one of the most serious problems the SES encountered during floods.
