South Australians are being warned to batten down the hatches as heavy rain and destructive winds hit the state.
More than 115mm of rain has fallen and wind gusts of up to 104km/h have been felt around Coober Pedy near the South Australian border on Tuesday.
The weather is being fed by the same severe weather system that caused flooding in the Northern Territory and the closure of Uluru National Park.
Storms will hit Adelaide at about midnight, the Bureau of Meteorology says, with strong winds of up to 125km/h continuing throughout the night.
Up to 50mm of rain is set to hit the capital.
