The SES has urged people to take care of their safety over taking photos of the storms.

South Australia's State Emergency Service (SES) is warning people not to risk their safety as abnormally high tides are set to lash the state's coastline.

A low-pressure system is moving across the state, bringing strong winds and rain.

SES state duty officer Ian Bonython urged people to be vigilant.

"Although it might be really fancy to get some really good pictures of the high tides and the waves, we just remind the public to be diligent with their safety and really urge the public to stay back, stay away from those jetties that are being impacted," he said.

The Bureau of Meteorology is warning of the potential for flooding in low-lying coastal areas when tides rise this afternoon.

It has issued a coastal hazard warning for abnormally high tides for all of the state's coastline.

A severe weather warning is in place for dangerous winds of up to 90 kilometres per hour in the Mount Lofty Ranges and the Flinders Ranges

There is a gale wind warning for the central coast, the south central coast, Investigator Strait and the upper South East coast.

The SES said it had received about 200 requests for help in the past 24 hours.

The majority of requests have come from Adelaide and the Adelaide Hills, due to wind damage and minor flooding.

SES chief of staff Robert Charlton said people should prepare for rapidly changing conditions.

"So, certainly the warning area is likely to extend over the next 12 hours into Wednesday morning, so perhaps, you know, 12 to 24 hours," he said.
