Storms are often accompanied by torrential rain, strong winds, large hailstones and lightning. Storms can cause flash flooding, unroof buildings, and damage trees and powerlines.
Storm and flood damage in South Australia often has a higher average annual cost than bushfires.
You can be indirectly affected by storms even if your property is not actually damaged. If access roads are cut or you have no power or telephone, you need to know what to do and where to turn for help.
Storms can also give rise to tornadoes. Penola, Karoonda, Renmark and Port Broughton have suffered significant damage as a result of destructive tornadoes hitting their towns.
