South Australia is set for another day of extreme pre-summer heat, with temperatures again expected to exceed 40 degrees Celsius in some parts and a top of 39C expected in Adelaide.
Total fire bans have been imposed for 12 districts across the state and a cool change is not expected to arrive until late in the week.
“On Thursday, temperatures will exceed 40C in the north and east of South Australia ahead of a cool change,” meteorologist Matt Collopy said.
“Cooler conditions will spread across western and southern parts of the state on Thursday then extend to remaining parts on Friday.”
Overnight temperatures are expected to remain in the low to mid 20s for many parts of SA.
Mr Collopy warned of continuing high fire danger, after crews tackled a number of scrub and stubble blazes on Tuesday.
Country Fire Service crews are working to contain a fire at Kyeema, east of Hope Forest, south of Adelaide.
The fire has burnt through about 75 hectares of scrub with strike teams working overnight to try to gain the upper hand before temperatures soar again.
The CFS said the fire was not threatening any homes, but it is causing smoke at Willunga, Aldinga Beach, Sellicks Beach and surrounding areas.
“The combination of the very hot conditions and fresh north-westerly winds will result in severe to extreme fire weather conditions across much of the state on Wednesday and Thursday,” he said.
Adelaide hit a top temperature of 36C on Tuesday, which was 10C above the mid-November average, and the Bureau of Meteorology warned parts of South Australia could expect maximum temperatures about 12C above their averages today.
“Similar temperatures are expected on Thursday ahead of a cool change extending across western and southern parts of the state during the day,” Mr Collopy said.
