The Bureau of Meteorology has issued a Coastal Hazard Warning for parts of South Australia, including Adelaide Metropolitan, Mount Lofty Ranges, Lower and Eastern Eyre Peninsula, Yorke Peninsula, Mid North and Flinders districts. This alert, issued at 4:23pm today, Monday, June 23rd, predicts abnormally high tides at Tuesday’s high tide times.
A cold front moving over South Australian waters on Tuesday is expected to generate strong to gale-force southwesterly winds. These conditions could cause elevated surf and higher than normal sea levels, particularly around the Spencer Gulf and Gulf St Vincent. The warning suggests that tide levels could rise well above the normal high tide mark during the Tuesday afternoon and evening high tides.
According to the Bureau, at the Outer Harbour tide gauge, sea levels may reach between 3.6 and 3.8 metres above the lowest astronomical tide. While these levels are not anticipated to be as high as those seen in late May, it’s important to note that the situation might evolve.
In response to these conditions, the State Emergency Service has offered several safety advisories. Public warnings urge avoiding coastal areas, checking moorings and lines for watercraft, and not walking, riding, or driving through floodwaters. The high sea levels combined with windy circumstances may also lead to localised damage and coastal erosion along Adelaide beaches.
Aside from the Coastal Hazard Warning, a Severe Weather Warning for damaging winds has also been declared for the same regions. Residents and visitors in affected locations, including Port Lincoln, Whyalla, Port Augusta, Port Pirie, Port Wakefield, and Victor Harbor should prepare for impactful weather conditions.
The State Emergency Service says unusually high tides present serious dangers, particularly to swimmers, surfers, and rock fishers. People are advised to stay informed by monitoring updates on warnings and current weather conditions.
To keep up to date, the public can access warnings through TV and radio broadcasts or visit the Bureau’s website.
Emergency assistance related to the storm or flood can be sought from the SES by calling 132 500, while life-threatening emergencies should be reported directly to Triple Zero (000).
