The Bureau of Meteorology has issued severe weather warnings for damaging winds across the New South Wales and Victorian alps and much of Tasmania, with blizzards possible in both alpine areas from Monday afternoon. A gust of 139 km/h was recorded at Scotts Peak Dam, in Tasmania's south west, at 5.51am.

The warnings were issued between 10.41am and 10.56am on Monday, as a cold front embedded in a strong westerly airstream crossed Tasmania. The Snowy Mountains warning had been easing over the weekend. It was reissued on Monday morning with blizzards added.

Above 1900 metres in the Snowy Mountains, the Bureau forecasts winds averaging 80 to 90 km/h with peak gusts up to 110 km/h from Monday afternoon. Isolated damaging gusts near 90 km/h are possible below that level. Thredbo, Perisher Valley and Charlotte Pass are inside the warning area, which runs into early Tuesday. Perisher Valley recorded a 94 km/h gust at 1.58am. The NSW National Parks and Wildlife Service recommends that back country travel be postponed until conditions improve.

In Victoria's north east and Gippsland above 1500 metres, winds are forecast to average 60 to 70 km/h with peak gusts around 100 km/h, again with blizzards possible. Falls Creek, Mount Hotham and Mount Buller are named. That warning eases early on Tuesday.

Tasmania's warning covers King Island, the Furneaux Islands and the state's west, north west and central north, with winds averaging 55 to 65 km/h and peak gusts in excess of 100 km/h through the afternoon, easing late in the evening. Low Rocky Point recorded a 113 km/h gust at 6.09am.

Coastal hazard warnings for abnormally high tides are current in both Tasmania and Victoria for Monday evening's high tide. In Tasmania, sea water flooding of low lying areas is likely between Southport and Maria Island, taking in Hobart, Bruny Island, Huonville, Port Arthur and Lauderdale. The Bureau gives a benchmark: "The high tide on Monday evening is expected to be about as high as that of the 24th of June 2025 - similar inundation impacts are possible." In Victoria, sea water flooding is possible from Cape Schanck to Point Hicks, including Phillip Island, Hastings, Inverloch, Port Albert and Lakes Entrance.

Three flood warnings are current in Victoria's north east. A new minor flood warning was issued for Seven Creeks at Euroa, where the gauge sat at 2.31 metres and steady and may reach the 2.50 metre minor flood level on Monday evening. Minor flooding is already occurring on the Kiewa River at Bandiana. The King River at Docker Road Bridge was at 3.16 metres and may pass its 3.70 metre minor flood level overnight.

Snow is falling across the Victorian resorts, with the snow level above 1400 metres on Monday and dropping to above 1200 metres on Tuesday. In Tasmania the Bureau expects snow down to about 600 metres on Monday evening. Sheep graziers warnings are current for the Snowy Mountains and for Tasmania's Upper Derwent Valley and south east. The Bureau cancelled the sheep graziers warning for the Southern Tablelands.

Western Australia and the Northern Territory have no warnings current.

The westerly airstream weakens on Wednesday as a high pressure system over the Bight ridges in, and the Bureau expects the front to clear. The next round of warnings is due by 5pm on Monday.
