Easter washout looms as Cyclone Megan heads south

A massive weather system that pummeled Australia's interior over the past week has begun its migration into the southeastern states, threatening to dampen Easter holiday plans across multiple regions through the long weekend.

The narrative began when ex-Tropical Cyclone Megan swept across the Northern Territory, parts of Queensland and northern Western Australia, dumping extraordinary rainfall totals. Rabbit Flat recorded its wettest March on file—277mm in just seven days. Alice Springs copped its heaviest 72-hour rainfall in nine years with over 150mm, while the Queensland township of Hughenden notched its most severe March precipitation in three decades. Satellite imagery captured a 7000km cloud band stretching across the continent toward the east of New Zealand.

As the Easter long weekend got underway over the past couple of days, that rain system began its slow journey southeastward. Forecasters predicted western South Australia and NSW would feel the system first, with 30mm expected across broad areas and isolated pockets receiving as much as 100mm. Crucially, a cold front was due to collide with the rain band on Monday, intensifying the system and driving it toward the NSW coast and central Victoria. Between 40 and 60mm was forecast for both states by Tuesday, while damaging winds threatened Victoria and flooding risk loomed over southern NSW.

The opening days of the long weekend played much as forecast. Friday and Saturday delivered warm, dry conditions across the south. Sydney sat at a pleasant 25°C under partly cloudy skies, Melbourne enjoyed similar warmth, and Adelaide basked at 31°C. Canberra soared to 29°C. The north, however, remained wet—Queensland's Townsville faced 8mm on Friday with light showers persisting, while Darwin continued to endure 10mm daily as Megan's tail lingered over the territory.

The shift came as the long weekend progressed. Sunday brought the first real warning signs—showers arrived across South Australia as forecast—while the system continued its southward march. By Monday and beyond, the full brunt would hit. Victoria faced a sharp temperature plunge and intensifying rainfall. New South Wales, especially the far west and northern coast around Byron Bay, was set for the heaviest falls. The system would intensify further through Tuesday and Wednesday, bringing 40-60mm and the threatened damaging winds and flooding.

For travellers hoping Easter would deliver beach and barbecue weather across the southeast, the pattern delivered real disappointment. The offsetting benefit came in genuine relief for inland water sources struggling through seasonal drought—a partial silver lining to an otherwise sodden long weekend.
