A man has been rescued from a car crushed by a fallen tree and a teenage girl has been saved from a fast-moving creek in the Adelaide Hills, with a number of roads across the city remaining closed due to floodwaters.
On Sunday morning, the state had recorded its wettest 24-hour period yet this year, with the SES receiving more than 400 calls for help yesterday.
The majority of calls came from around suburban Adelaide.
It comes a week after a mini tornado hit Adelaide's northern suburbs.
SES state duty officer Brenton Clarke told ABC Radio Adelaide it took crews an hour to rescue the man who was trapped in his car at Beverley in Adelaide's western suburbs.
"He was trapped in the car for about an hour before crews could actually make space for him to get out of the vehicle," Mr Clarke said.
"He only suffered minor injuries but some really good work there from State Emergency Service, Metropolitan Fire Service and SA Ambulance as well."
He said a 16-year-old girl who fell into a fast-moving creek at Bridgewater on Sunday was also safely rescued.
"A young girl was caught in a creek, fortunately CFS crews who were on the scene were able to get her safely out of the water," he said.
SES urges caution for week ahead
Darley Road in Paradise in Adelaide's north-eastern suburbs is closed due to floodwaters, as is Sir Donald Bradman Drive near Augusta Street in Cowandilla.
Floodwaters are also affecting roads at Beverley and Christie Downs.
Greenhill Road was closed on Sunday for a couple of hours due to flooding.
Unley Mayor Michael Hewitson rode his bike around the area to inspect flooding yesterday.
He said leaves may have blocked drains near the King William Road intersection.
"I suspect it's autumn leaves, but I don't know," he said.
"That's an area of concern and something that needs to be addressed."
Duty forecaster from the Bureau of Meteorology Simon Timcke said after records rains over the weekend, the state could expect some reprieve this week.
"A number of places around the hills still picked up 20 millimetres to 30mm [on Sunday]," he said.
"Pretty wet conditions, pretty windy as well conditions over the weekend, but the trend over the next few days is for a gradual easing of the showers and the wind."
Despite the calmer conditions forecast, Mr Clarke urged people to be cautious this week, and to avoid driving into floodwaters.
"We are still expecting some rain for the reminder of the week and it's just a reminder for people that whilst it's calm and clear [make sure] things are tidy around the house, make sure those drainage points are clear and just be mindful as you're driving around on the roads," he said.
"If there are any flooded areas on the road, don't drive through them, just wait for the water to subside."
