SA Heatwave Hits Tour Down Under
South Australia's three-day heatwave has hit cycling's Tour Down Under with organisers cutting short Thursday's third stage.
The mercury is tipped to hit 41C in Adelaide and go into the mid-40s in some regional centres with only slight relief from the extreme conditions expected by the weekend.
Tour Down Under race director Mike Turtur says riders and officials have agreed to cut Thursday's race from Glenelg to Victor Harbor by 26km to ensure the safety of all concerned.
"The safety and welfare of the riders, spectators and everyone involved with the race is always our primary concern," he said.
The public participation ride scheduled for earlier on Thursday has been cancelled.
The Bureau of Meteorology says the blast of hot weather is being fuelled by a very hot air mass being dragged down from central Australia.
The Country Fire Service has declared extreme conditions in two SA districts with seven more considered extreme.
The conditions have prompted the Australian Energy Market Operator (AEMO) to issue a lack of reserve notice for a short period in the afternoon.
It expects the electricity reserve - the amount above forecast demand - will be 788 megawatts, below the 1100 megawatts of contingency power the operator requires.
But Energy Minister Tom Koutsantonis said the state is well prepared and electricity supplies will be sufficient.
