SOUTH Australia is preparing for its heaviest downpours in more than three decades with authorities warning heavy rain may lead to flash flooding in large parts of the state.
The wild weather comes on the back of the state's worst bushfires in more than a decade that tore though the Adelaide Hills this week destroying 27 homes and more than 100 outbuildings.
Towns in the state's far north are expected to bear the brunt of the storm before it heads south over the weekend to more populated areas of the state.
The Bureau of Meteorology said heavy rain and thunderstorms are expected through until early next week and may produce further falls of 50-150mm.
The bureau predicts torrential rain could cause a serious risk of flooding. Damaging winds with gusts in excess of 90kmh are expected to batter the state.
