Storms special report

Troughs over the east will trigger rain, showers & storms.

Heavy falls are likely in southern Qld & eastern NSW.

A linked trough over western NT will also trigger showers & storms.

A high will keep the remainder mostly dry & combine with a trough to drive hot winds to southern WA. We have 3 maps now, first showing National 24 hours of accumulated rain over 8 days, second QLD and the third Likelihood of rain over 10mm. As we get closer to the systems impacting QLD we can break it apart more. We are in a period of uncertainty where forecasting beyond 5 days involves some big margins of error.

  • Strong Wind Warning for Monday for Geraldton, Lancelin, Perth, Bunbury Geographe & Leeuwin coasts. Cancelled Monday for Perth Local Waters.

  • Strong Wind Warning for Tuesday for South East Coast.

  • Fire Weather Warning for Lower West Inland and Brockman.
