Crucial parts of many levees are made out of clay and it is unclear how they will react to the extreme heat while bearing the load of swelling floodwaters.
South Australia State Emergency Service CEO Chris Beattie said it is inevitable
"I think it's inevitable we'll continue to see levees fail," Beattie said.
"We'll be very pre-emptive around warnings and messages to the community in terms of being prepared to evacuate and when to evacuate."
