Rain sweeping South Australia, with more to come RAIN is sweeping across South Australia today, with motorists being warned to take extra care on slippery roads. A low pressure system and cold air has been fuelling instability and shower activity across the state.

Rain is expected to ease as the band moves east in the afternoon, before a new front brings increasing, more-intense showers.
