Perth and WA weather: The Bureau of Meteorology is issuing a strong wind warning and fears significant coastal erosion

Western Australians are being told to shut the hatches with more damaging winds that will batter the state after thousands were left without power and property damaged overnight.

Destructive winds will continue over Perth and the south of the state, with gusts expected to reach 120km/h along the west coast south of Jurien Bay by late afternoon.

The Bureau of Meteorology has issued a severe weather warning for Goldfields, Eucla, Lower West, South West, South Coastal, South East Coastal, Great Southern, Central Wheat Belt and parts of Gascoyne, South Interior and Central West districts.

A strong wind warning also applies to Melville Waters and the Gascoyne Coast.

These winds are expected to continue into dawn Wednesday and the bureau has warned that gusts of wind can cause damage to homes and property, particularly along the coast and in the near inland, and will become more isolated further inland.

That’s not the only grim news for our coast, as sustained strong surf with waves in excess of seven meters could expose the west-southwest to significant coastal erosion.

“Strong westerly winds are whipping up heavy surfing conditions with waves reaching 8m off Rottnest Island this morning. These winds will continue until late Wednesday and sea conditions will not ease until Thursday,” BoM warned on Twitter.

At Cape Naturaliste in the southwest of the state, waves reached 9 m, Rottnest Island 8.7 m, Jurien Bay 6.6 m and Mandurah 6.5 m.

Wind gusts of more than 90 km/h were registered on Tuesday, from Bunbury at 91 km/h to Mandurah at 109 km/h and Cape Leeuwin at 135 km/h.

A series of strong cold fronts will continue to cross the south of the state today and into Wednesday. Showers and thunderstorms are likely along these fronts.

This weather system is expected to be windier and longer lasting than a typical front and likely to produce the type of weather seen only about once a year.
