Rising temperatures, dry air and gusty winds are bringing the highest fire danger in almost a month to parts of South Australia today.
A hot air mass that has stagnated over Western Australia for more than a week will filter into South Australia today, ahead of an approaching cold front.
Hot and dry air will be moving around parts of state in winds gusting up to 40-60km/h, producing severe Fire Danger Ratings, the third highest level.
South Australia's Country Fire Service has declared a total fire ban for Tuesday across the western half of the state, covering the West Coast, Lower and Eastern Eyre Peninsula and North West Pastoral districts.
This type of heat and fire danger have not been experienced for almost a month.
The last time Wudinna experienced a Fire Danger Rating over 50, the lower threshold of severe, was on 11th February. On that day the temperature soared to 45 degrees as winds gusted over 30km/h.
Temperatures today will reach up to the high thirties, while Adelaide tops out in the mid-thirties, the warmest day in almost a month.
A gusty southwesterly change with the front will bring an end to the early autumn warm spell, reaching Adelaide during the evening.
A cooler air mass in the wake of the change will ease the fire danger on Wednesday. The fire threat will be replaced by milder and gusty southerly winds, a notable change to today's summer-like rerun.
