Abnormally high tides for the South Australian coastline

Weather Situation: A deep low-pressure system is forecast to track eastward near the South Australian coast on Monday before moving over Bass Strait on Tuesday, bringing strong to gale-force westerly winds and elevated sea levels.

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. Tides are 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.

A separate warning for DAMAGING WINDS is also current. For more details, refer to https://www.bom.gov.au/weather-and-climate/warnings-and-alerts

The State Emergency Service advises the following:
* Unusually high tides are dangerous to swimmers, surfers and rock fishers. Stay away from coastal areas until conditions subside.
* Know your limitations around beaches, tidal rivers and creeks. Monitor warnings and conditions. Supervise children at all times.
* If you have a moored boat or watercraft, check that your mooring and lines are secure.
* Be aware that unusually high tides could cause flooding at the coast.
* You should never walk, ride or drive through floodwater.

The next Coastal Hazard Warning will be issued by 11:00 pm ACST Monday.
