CFS battles 45 fires in catastrophic conditions

The CFS says it has responded to at least 45 fires across South Australia today, with acting deputy chief officer Rob Sandford praising volunteer firefighters for an "amazing" effort in the "worst conditions that our people could be operating in".

"A number of those fires were of concern to us but the crews have done an outstanding job in very trying conditions," he said.

"The work that our crews on the ground, supported by the community, have done to halt these fires has been nothing short of amazing.

"We haven't been advised of any losses yet ... or any injuries been reported either."
