A major winter storm system is sweeping across southern Australia, bringing a hazardous mix of heavy rainfall, damaging winds, and highly volatile alpine conditions. The intense cold front, which made landfall on the Western Australian coast, is moving rapidly eastward and is expected to intensify over South Australia, Victoria, and New South Wales over the coming days.

Flooding Rains and Agricultural Relief

While the agricultural sector welcomes the incoming rain—which promises the most significant downpours in over a month—the sheer volume of water has prompted serious safety concerns. Emergency services have already issued a flood watch for ten catchments across the Victorian ranges, where heavy rain is predicted to pool rapidly.

Total rainfall over the next five days is forecast to exceed 25 millimeters across vast areas of the southern continent. High-risk zones, including the Adelaide Hills and coastal regions, could see more than 50mm, while parts of northeast Victoria's high country could be drenched with up to 100mm of rain.

Damaging Winds Target Major Cities

Associated with a deep low-pressure system, destructive wind gusts are poised to cause widespread disruption. While Western Australia's southern coast bears the initial brunt—with Perth's coastal suburbs preparing for 80 km/h gusts—the wild weather will expand eastward. Adelaide is on alert for gusts reaching 70 km/h by Sunday afternoon.

By Monday, the strongest winds will shift to the eastern states. Major metropolitan hubs including Sydney, Canberra, and Melbourne could experience gusts exceeding the severe weather warning threshold of 90 km/h. Exposed coastal areas and alpine ridges may see extreme winds topping 100 km/h, bringing a high risk of fallen trees, structural damage, and widespread power outages.

Ski Resorts Face Dramatic Weather Swing

The wild weather presents a critical turning point for Australia's struggling ski season, which has suffered from substandard snow depths at lower elevations. Unseasonably warm temperatures ahead of the front will initially bring heavy rain rather than snow to alpine areas on Sunday, threatening the already depleted snowpack.

Initially, snow may fall down to 1,500 meters early Sunday morning, but warming temperatures during the day will push the snow line to only the highest peaks. The combination of rain and gale-force winds is expected to cause severe snow loss on low and mid-level slopes, creating hazardous and unpleasant skiing conditions.

A Massive Snow Dump on the Horizon

Fortunately for snow enthusiasts, a dramatic drop in temperature early Monday morning will see the rain transition into heavy snow. Forecasters project up to 40 centimeters of fresh snow within 24 hours starting Monday, accompanied by potential blizzard conditions.

A secondary cold front following closely on Tuesday and Wednesday is expected to deliver an additional 10 to 20 centimeters. This late-season surge could ultimately dump up to 50 centimeters of fresh powder on the higher slopes, setting up the best skiing conditions of the year so far, even if the initial snow quality remains somewhat wet and heavy.
