South Australia is bracing for an unusually cold snap along with the prospect of heavy rain.
The Bureau of Meteorology says a weather system moving across the state on Wednesday will bring up to 60 millimetres of rain to the Adelaide Hills and good falls across a wide region by the end of the week.
Maximum temperatures are also expected to be lower than average, with Adelaide likely to struggle to hit 15C on Wednesday.
"While these temperatures are not record-breaking, they are quite significant for this time of year," forecaster Kylie Egan said.
"You have to go back to 2008 to see temperatures this cold this early in the season."
The rain this week will add to SA's wet start to the year.
Adelaide has had 130mm so far this year compared with just 18mm at the same time last year.
Ms Egan said the outlook also suggested a high chance of above-average rainfall across South Australia during winter.
