Cold temperatures and gusty winds for south-east Australia as major flooding continues in New South Wales


A late spring cold burst is moving over south-east Australia, with damaging winds, cold temperatures and low-level snow impacting multiple states.

There have been strong to damaging winds along the south-east. Wind gusts of 70-90 km/h have been observed across parts of Melbourne, leading to trees toppling in some parts of the city. Small hail was also reported in some suburbs in Melbourne on Monday morning.

Some of the highest rain totals in the 24 hours to 9am AEDT Monday include:

  • 63 mm at Perisher Valley, NSW
  • 43 mm at Thredbo, NSW
  • 36 mm at Tooma Dam, NSW
  • 36 mm at Lake Margaret, Tas
  • 35 mm at Burbury Pluvio, Tas
  • 33 mm at Portland, Vic

Some of the strongest wind gusts in the 24 hours to 9am AEDT Monday include:

  • 126 km/h at Hogan Island, Vic
  • 119 km/h at Wilsons Promontory, Vic
  • 109 km/h at Cape Grim, Tas
  • 107 km/h at Neptune Island, SA
  • 107 km/h at Mt Hotham, Vic

Widespread strong to damaging winds above 90km/h will continue on Monday through a Severe Weather Warning area, which covers parts of South Australia, Victoria and New South Wales/ACT. Peak gusts approaching 100km/h are also possible, especially about the coast and elevated terrain.

Winds will ease from the west into tonight, but the risk of damaging winds may persist across elevated parts of Victoria and New South Wales into Tuesday morning.

Due to ground saturation, the risks of trees and powerlines toppling are elevated.

A Road Weather Alert and Bush Walkers Alert are current for Tasmania due to snow-covered roads.

For the rest of today, a cold and brisk south-west airstream will continue to move over south-east Australia with a surface rough.

This will maintain showery conditions across the south-east with local hail and thunder possible for south-east South Australia, southern Victoria and western Tasmania.

Maximum temperatures will be 6-14 degress below average for this time of year, but the gusty winds will make it feel much colder. Snow is possible above 500m in Tasmania, and 800-900m in Victoria and New South Wales, and there has already been snow at the ski resorts.

For tomorrow, showers will continue across south-east South Australia, Victoria and Tasmania; however, they will become more isolated and will contract to coastal and elevated areas by the evening. Another burst of winds will move through, this time mostly impacting Tasmania, and a Severe Weather Warning may be issued for parts of Tasmania.

Maximum temperatures on Tuesday will rise slightly but will remain 5-10 degrees below average.

On Wednesday, a high pressure ridge will develop over south-east Australia which will help to clear conditions, although patchy showers are still possible.

Temperatures will gradually rise into the latter part of this week but will remain slightly cooler than average on Thursday.

Major flooding continues to impact many communities across inland New South Wales, and along the Victorian border.

Moderate flooding is occurring at Forbes, and the peak has now moved through Condobolin, but with Major Flooding.

Floodwaters are now making their way downstream, including into South Australia.

Residents and communities living on or near any rivers, creeks, and streams or in low-lying areas should stay up to date with the latest forecasts and warnings via our website and BOM Weather app and follow the advice of emergency services.
