Flood warnings across SA coast as ‘abnormally high tides’ hit
A coastal hazard warning has been issued for large parts of the state with the Bureau of Meteorology warning abnormally high tides could flood roads and homes.
Eleven warnings have been issued by the State Emergency Service for areas stretching from Port Pirie, Ceduna and to Robe in the South East of abnormally high tides threatening flooding.
It was understood that Kingston SE was the main area of concern for the SA State Emergency Service, which had deployed sandbags and operational support to assist the community.
Residents at Arno Bay and Port Kenny were warned that low–level properties and roads could be flooded for a “short duration during the peak tide times” as a coastal surge hits.
A storm surge warning was issued for Middle Beach, with the SA State Emergency Service saying that high tide this afternoon could cause coastal flooding, which may impact roads and low-lying areas and “may result in isolation of the community”.
Residents were being warned to “prepare your family and home for flooding in your area”, to remove valuable items to a safe place and if it was safe, to ensure drains and gutters were clear.

“A deep low-pressure system to the south tracks eastward moving over the Bass Strait today, bringing strong to gale-force westerly winds and elevated sea levels,” the Bureau said.
“Abnormally high tides which may lead to sea water flooding of low-lying coastal areas are possible between Head of the Bight and the SA/VIC border, including Kangaroo Island.”
The Bureau said the Adelaide Hills region saw 30-50mm of rainfall on Tuesday, with 15–20mm expected for SA’s Eyre Peninsula and Yorke Peninsula.
Tides were likely to rise well above the normal high tide mark during the Tuesday afternoon high tide.
Locations which may be affected include Ceduna, Elliston, Port Lincoln, Port Pirie, Port Wakefield, Adelaide Metro Beaches, Victor Harbor, Kingston SE, Robe, and Port MacDonnell.
The tides make it dangerous for swimmers, surfers and rock fishers with a warning to stay away from coastal areas until conditions subside, the SES said.
The Bureau expected conditions to ease across SA by Wednesday, with the focus of the abnormally high tides moving into all Victorian coastal waters.
