By the Bureau of Meteorology, South Australia.

In the 24 hours to 9am Sunday there have been widespread rainfall totals of 20 to 35 mm recorded over the Mount Lofty Ranges with the largest totals recorded over the Onkaparinga catchment. This rainfall has caused water level rises in the upper Onkaparinga and Torrens catchments.

An intense low pressure system south of Kangaroo Island will move eastwards to be over western Bass Strait late Sunday evening.

Showers and possible thunderstorms are expected to increase again during Sunday afternoon and are likely to be heavy at times over the Mount Lofty Ranges. This is expected to cause renewed rises in water levels in rivers and creeks throughout the Mount Lofty Ranges. Localised minor flooding is possible from Sunday afternoon particularly upper Onkaparinga River from Oakbank to Verdun and may lead to some road closures.

The Bureau is continuing to monitor the situation and will issue catchment specific warnings if required

Weather Forecast:

Further rainfall totals of 40 to 60 mm are likely about the Mount Lofty Ranges for the remainder of Sunday.

People should refer to the latest warnings on the Bureau's website.
