Rain and hail across parts of SA

Marble-sized hail and heavy rain have hit parts of South Australia's Flinders Ranges as a band of severe thunderstorms moves across the state's east.

A severe weather warning has been issued for an area from Moomba in the northeast to Naracoorte in the southeast as well as the Adelaide Metropolitan area.

The Bureau of Meteorology says the storms are likely to be slow moving and may lead to flash flooding.

There is also a risk of damaging winds.

Towns outside Adelaide that may be affected include Hawker, Leigh Creek, Jamestown, Clare, Port Pirie, Murray Bridge, Naracoorte and Renmark.

By mid afternoon Bruce, in the Flinders Ranges, had received 17mm of rain, which fell over a period of just 20 minutes.
