An unseasonally cold October night in South Australia heralded some morning surprises today, with light snow fall witnessed on the Mount Lofty and Flinders Ranges

Temperatures dropped to just 4.9 degrees in Adelaide overnight, with Mount Lofty dropping to 0.4 degrees, Keith West 1.8 and Clare 2.3.

Light snow and sleet has been seen around Hallet, north of Burra, throughout areas of the mid north of the state, and along parts of the Mount Lofty Ranges.

Heavy rain and strong winds overnight brought down powerlines, crushed a vehicle in a Brighton shopping centre carpark when a sign collapsed upon it, and kept local SES volunteers busy overnight responding to emergency call-outs.
