THE Bureau of Meteorology has given its first catastrophic fire danger warning for the 2019-20 season.
It is urging communities to plan ahead of building heat and strong winds expected on Wednesday.
BoM acting supervising meteorologist Paul Lainio forecast parts of SA to experience potentially record-breaking maximum temperatures for November.
"Those towns that may break temperature records are in the south and west of the state and include Victor Harbor, Nuriootpa, Keith, Naracoorte, Murray Bridge and Robe and Lameroo," he said.
"Wednesday's forecast for Adelaide at this stage is 42°C, just shy of West Terrace's hottest November day in 1962 on November 30 of 42.7°C."
Across SA, temperatures on Wednesday will peak 8-18°C above average ahead of a cold front that's accompanied with strong winds, Mr Lainio said.
"The strong cold front will move from the west of the state in the afternoon and evening, before heading over central and southern parts overnight, then through the far north east during Thursday," he said.
"Northerly winds would increase during Wednesday morning and were expected to average 40-50km/hr over most of the state, reaching 50-60km/hr over southern and western parts.
"Winds will turn southwest to southerly around 40-50km/hr behind the cold front and are likely to be quite gusty."
According to the BoM, SA has experienced its driest first nine months of the year on record.
October was also drier than average for the state.
Mr Lainio expected the windy conditions to increase the potential for raised dust.
"Temperatures will drop significantly following the cold front, with many places in the south expected to be 15-20 degrees cooler on Thursday," he said.
"The Bureau is urging communities listen to any advice from the Country Fire Service or Emergency Services and also the Department of Health."
