Twelve South Australian districts are currently on high alert as the scorching temperature and gusty wind prevailed within the state.

According to the Country Fire Service spokesman they have 13,500 volunteer firefighters on the go, as well as helicopters and water bombing planes getting ready for fire accidents. All are stationed throughout the different districts.

Today, there will be a spotter place, which will regularly check the Tour Down Under route. The plane will monitor the area from Prospect to Clare for fire outbreaks.

There's high potential for fire in the West Coast, Eastern Eyre Peninsula and North West Pastoral districts. There were nine discovered districts with high alert on fire including the Mount Lofty Ranges.

According to the weather bureau, the highest temperature could go up 30C to down 40C all throughout the state. In Adelaide, there's 39C being recorded and almost 29C at Kent Town.

The hot weather will be accompanied by a raging wind from the north to northwest with an average speed of 40km/h to 50km/h.

The spokesman is more worried about the wind because it can easily worsen and spread the fire if one does happen.

He hopes that the total fire bans will be strictly respected and followed by people. Their cooperation means much to keeping the entire place safe from fire accidents.

The spokesman suggested that people would restrain from grilling outside, making camp fires and doing other outdoor activities that involve fire. Also, he advised that tools like angle grinders, which could generate a spark be kept inside and temporarily stop the usage.

He also asked people to be watchful and be more cautious of their surroundings. If anybody witnesses any smoke, he or she must immediately dial triple-0.

The high risk of fire found at the Mount Lofty Ranges has provoked the Department of Environment and Natural Resources to temporarily lock the Mount Lofty Botanic Gardens today.
