A flood Watch and Act message remains in place for Stockport, north of Adelaide, because of a high risk the Light and Gilbert rivers could flood.
People living in Stockport are asked to prepare for flooding and leave if they require time to leave or if they are not prepared.
Heavy rain has fallen in the catchment area for Gilbert River, increasing the flow upstream.
More rain is expected in this area of the state's Mid North, with South Australian State Emergency Service (SES) warning a risk of floodwaters could impact Stockport.
Stockport was heavily hit by flash flooding in 2010 with dozens of homes destroyed.
The local community is hoping history does not repeat itself, with SES monitoring the levels of Gilbert River.
Local resident Kiraleigh Hewitt said water levels at both Gilbert and Light rivers have been rising since Sunday.
"The Hewitt family as well as the CFS and SES were door knocking yesterday afternoon every house in the affected area to give the residents notice, as many families are new and haven't experienced a flood before, and giving them warning about what may unfold, like it has previous years," Ms Hewitt said.
Flood advice is issued for Light and Gilbert, north of Adelaide while the threat of flooding has reduced at Renmark and Berri in the Riverland.
Renmark received 95 millimetres of rain in less than 24 hours while Loxton had 34 millimetres.
The Bureau of Meteorology predicts showers and possible thunderstorms will develop in the west tomorrow, extending to Flinders and North East Pastoral regions.
The bureau cancelled a severe weather warning issued earlier for parts of South Australia's south-east and Riverland.
SES duty officer Brenton Clarke said they received 167 calls for help on Sunday.
"Majority of those requests were in the Riverland area, where we had 98 requests for assistance and particularly Renmark where they were impacted by quite a significant thunderstorm cell and there were 70 requests for assistance," he said.
"Because of the amount of rainfall we've had over the last few days, the ground is obviously saturated and catchment areas are quite flooded, so any rain we do get, we'll be looking closely at the impacts it may have."
SES also reminded people to not drive through floodwaters.
"Earlier today we received a call for assistance after a motorist drove into floodwaters and became trapped," SES chief of staff Darren Halleday said on Sunday.
"It is a timely reminder that driving through floodwaters is never safe and it is the number one cause of death during flooding events."
