A man has been crushed by a tree that was brought down as strong winds lashed the Adelaide Hills, causing widespread damage and cutting power to thousands of properties.
The 71-year-old man was trying to clear a fallen tree from a road at Tungkillo when he was struck and killed by another tree.
His death came after winds gusting up to 100km/h swept across South Australia on Sunday night and into Monday morning.
The State Emergency Service took more than 500 calls for assistance, most for tree and other minor damage, including one incident where a man was rescued from a caravan which was tipped on its side.
The Country Fire Service also assisted with more than 250 incidents.
At one stage more than 13,000 properties were without power but SA Power Networks said it expected to restore most services by late Monday.
The Bureau of Meteorology said while conditions moderated during Monday, another vigorous cold front was expected to move through SA on Monday night and into Tuesday morning, bringing strong winds, heavy rain and possible thunderstorms.
A severe weather warning was issued for the southern Adelaide Hills and the southeast of SA with a chance of snow falling in the hills and in the mid-north.
A flood watch was also in place for the Mt Lofty Ranges with falls of up to 80mm expected.
Bureau of Meteorology acting regional director John Nairn said the worst of the weather was expected overnight on Monday and early on Tuesday with conditions moderating during the day.
Adelaide was forecast to have a top temperature of just 11C on Tuesday with up to 25mm of rain.
SA Power Networks spokesman Paul Roberts said efforts to restore services to affected properties was a major operation and some people should expect an extended period without electricity.
"We are not talking about minor repair and restoration jobs, but rebuilding of sections of the network in the Adelaide Hills that have been smashed by trees and tree limbs," he said.
"Given the major nature of the work required and the difficult conditions being confronted by crews, customers should be prepared for long duration power outages."
