South Australia’s coastline was rocked by a storm surge overnight, State Emergency Services saying Tuesday night’s levels “could be considered a ‘one in 10-year’ event”.

Locals shared footage to social media showing surging tides crashing over jetties and even surfers taking advantage of the swell on near the jetty of a metro beach.

Between 6pm last night and 6am this morning, the SES had 33 calls for assistance including flooding at homes, ceiling collapses and trees fallen on properties or driveways.

“We haven’t received any reports of coastal infrastructure damage as of yet but will be assessing these through the day,” an SES spokesperson said this morning.

SES crews rushed to a flooded street at Malvern in Adelaide’s south this morning and were on hand to deal with the impact of flooding along Glenelg’s coastline. Crews are continuing to respond to severe weather impacting the leafy inner suburbs of Hyde Park and Kings Park.

Extensive beach sand was washed away from metropolitan beaches with the tidal surge sweeping away tonnes of trucked sand dumped under the state government’s coastline replenishment work.

One dune care group opposed to the program saying the community must “bear the continual disruption and despair as we watch it wash away with the first big storm”.

Yorke Peninsula and Port Pirie saw peak sea level heights hit overnight after an abnormal high tide surge warning was issued, the SES reducing the threat levels for both areas as of Wednesday morning.

The coastal flood warnings for Port Lincoln, Arno Bay, Tulka and Middle Beach had also been reduced by SES, but Outback South Australia was still advised to monitor conditions.

Stay informed, daily

Seven fallen trees across the state were receiving SES attention this morning and there was flooding at a home in Balaklava.

Jetties were closed across the state on Tuesday, including Henley Beach, Brighton and Glenelg, due to severe weather. The Sidewood Estate cellar door in the Adelaide Hills was closed after flash flooding.

Power outages are affecting Balhannah, Carey Gully, Mount George, Christies Beach, South Plympton and Uleybury, with about 911 customers affected across the state, according to SA Power Networks.

It comes after 11 warnings for severe flooding were issued after stormy weather and heavy rains wreaked havoc across the state, with roads inundated and the SES called to 180 incidents on Tuesday.

The SES spokesperson said it appeared the state was at the “tail end” of the extreme weather and were unlikely to see further severe impacts.

More to come.
