South Australians are being warned of flash flooding this afternoon, with the Bureau of Meteorology issuing an updated Severe Thunderstorm Warning for heavy rainfall across Adelaide and several surrounding regions.
The warning, updated at 2:51pm on Sunday, August 9, covers the Mount Lofty Ranges and parts of the Adelaide Metropolitan, Mid North, Murraylands and Upper South East districts.
A line of showers and thunderstorms is moving across the state, with areas of heavy rainfall possible along a stretch extending from Clare through to parts of the southern Fleurieu Peninsula.
The Bureau says severe thunderstorms are likely to produce heavy rainfall that could lead to flash flooding across the warning area over the next several hours.
Clare, Gawler and Victor Harbor are among the locations that may be affected.
The latest warning follows a Severe Weather Warning issued earlier on Sunday for damaging winds across parts of the West Coast, Lower Eyre Peninsula, Yorke Peninsula, Flinders, Mid North and North East Pastoral districts.
That warning came as a cold front connected to a low-pressure system in the Bight moved across South Australia, bringing a gusty west to southwesterly change.
Damaging winds averaging 55 to 65km/h, with peak gusts of around 90km/h, were forecast for parts of the Eyre and Yorke peninsulas, while the Flinders Ranges could experience winds averaging 60 to 70km/h and gusts of around 100km/h.
The latest thunderstorm warning brings an additional heavy rainfall threat further south, including parts of metropolitan Adelaide and the Fleurieu Peninsula.
The SES is urging people in affected areas not to drive, ride or walk through floodwater and to keep clear of creeks and storm drains.
People should also stay indoors and away from windows while thunderstorms are nearby.
For emergency storm or flood assistance, contact the SES on 132 500. In a life-threatening emergency, call Triple Zero (000).
The weather situation continues to develop, and South Australians are encouraged to keep up to date with the latest Bureau of Meteorology warnings.
