A mini-tornado has cut a path through an Adelaide suburb, bringing down powerlines, trees and damaging houses.
The windstorm hit Salisbury, about 20km north of the Adelaide CBD, shortly after 5am on Monday, the South Australian State Emergency Service says.
More than 200 people called for help, with SASES reporting it was difficult to get to some areas due to a large amount of debris blocking roads.
It struck as a severe weather cell passed across the north of the city, dumping more than 70mm of rain in some areas.
Social media photos showed many large trees fallen across roads and power lines.
Other images on Facebook showed cars stranded on flooded roads and damaged buildings.
More than 1850 homes and business across the city remained without power about 2pm, with SA electricity distributor, SA Power Networks, warning some customers may be without power until Tuesday
A severe weather warning for damaging wind remains in place for much of the state.
