Severe weather warnings for most of southern Australia for rest of the week

02/08/2022

Issued: Tuesday, 2 August 2022

Severe weather warnings are current for most of southern Australia including southern WA, southern SA, Tasmania, Victoria and southern NSW with two complex weather systems bringing damaging winds, heavy rain and dangerous seas.

Marine wind warnings are current for damaging seas across most of the southern coast. One of the systems has already brought swells of up to 9 m off the WA coast overnight.

The systems are likely to bring severe weather conditions to WA, SA, NSW, Victoria and Tasmania states until Thursday.

There is a low risk of minor flooding in some regions, and rainfall may melt some snow in the Alpine regions and could lead to increased river rises.

The Bureau is monitoring the situation closely and will update its forecasts and warnings regularly.

Communities are encouraged to stay up to date with the latest forecasts and warnings via the Bureau's website and BOM weather app and follow the advice of emergency services.
