STORM DETAILS
At 2:51pm on Friday 29 May 2026 the Bureau of Meteorology advised a deepening low pressure system is forecast to approach the southwest during Sunday bringing strong to gale force westerly winds, elevated sea levels and large and powerful waves. The low pressure system is expected to move east during Monday with sea levels and waves remaining elevated until Monday afternoon.
Abnormally high tides which may lead to sea water flooding of low-lying coastal areas are likely between Gregory and Cape Naturaliste. Tides are likely to rise well above the normal high tide mark during Sunday morning. Tides are also expected to rise well above the normal high tide mark for coastal areas between Jurien Bay and Israelite Bay during the Monday morning high tide.
Damaging surf conditions which may lead to coastal erosion and localised damage to coastal infrastructure are possible between Gregory and Cape Naturaliste from the Sunday morning high tide. Wave heights are expected to significantly increase during Sunday with damaging surf conditions possible between Gregory and Cape Leeuwin through to Monday afternoon.
Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas.
A separate warning for damaging locally destructive winds and heavy rainfall is also current. For more details, refer to https://www.bom.gov.au/weather-and-climate/warnings-and-alerts
