Overnight Adelaide received its heaviest rainfall since flooding in December 2010, with more to come.
Yesterday afternoon rain began to develop in coastal parts of South Australia, before it spread inland and became widespread. By 9am this morning Adelaide had picked up 35mm, its heaviest June rainfall in seven years.
On the Fleurieu Peninsula there have been reports of flash flooding with a number of suburbs receiving more than 50mm.
In the Mount Lofty Ranges, Kuitpo had its heaviest rain in 12 years with 53mm.
The rain will continue through much of the day keeping it very cold. From last night and until mid morning the temperature continued to drop, rather than increasing with the usual daily heating. The mercury was still at 11 degrees just after midday, which was the lowest it got during the night.
The heavy rain was due to the passage of a strong cold front last night, followed by a low pressure system. The movement of the low pressure system towards Adelaide has brought an increase in wind today and should increase further tonight, making conditions outside feel even colder due to the wind chill factor.
Rain will continue, particularly along the coast and ranges. However, for inland areas rain will ease considerably during the night.
On Friday the rain will clear before a few lighter showers arrive on Saturday with the movement of a weak cold front. Adelaide is expected to stay cold through until at least Monday with temperatures likely to be below the June average of 16 degrees each day.
