Wintery blast moves through SA

A severe weather warning has been issued for South Australia's southern coastal regions as a blast of wintery weather moves across the state.

Wind gusts of up to 100km/h are forecast on Monday with locations likely to be affected including Port Lincoln, Mount Gambier, Murray Bridge, Kingscote, Naracoorte, Cleve, Minlaton and Victor Harbor.

The Bureau of Meteorology says a vigorous cold front will move across the west and south bringing significant rain and hail to some regions.

Adelaide is forecast to have up to 15 millimetres on Monday and then up to 20mm on Tuesday.

Total falls could reach 60mm in the Adelaide Hills.

The strong winds ahead of the cold front will also lead to raised dust in some country regions.

Moving into Tuesday, snow is also possible on the highest peaks in the Flinders Ranges with some top temperatures barely rising into double figures.
