A dramatic shift in weather patterns is anticipated across eastern and southeastern Australia over the coming days, with temperatures set to drop significantly.
According to Jonathan How from the Bureau of Meteorology (BoM), regions including New South Wales, Victoria, Tasmania, South Australia, and Brisbane will experience notably cooler conditions.
Central Australia has already seen wet weather, with record rainfall reported around Uluru.
Yulara Airport recorded its highest September rainfall in 37 years, with 31.6 mm falling within 24 hours up to 9 a.m. on September 24, surpassing the previous record of 24.8 mm set in 2010.
Additionally, Curtin Springs reported 33.4 mm, marking its highest September daily total in 72 years of records.
Record rainfall was reported at Uluru; snow is expected in Tasmania and southern NSW.Meteorologist Miriam Bradbury indicated that heavy rain, storms, and potential flooding will continue in Western Australia, the Northern Territory, and South Australia before advancing to eastern states by Thursday.
In Sydney, temperatures are expected to plummet from a high of 31°C on Wednesday to between 19°C and 20°C on Thursday and Friday. This significant drop is notable, given that average September maximums for Sydney typically hover around 20°C.
The BoM forecasts widespread rainfall in New South Wales, estimating 40 mm to 60 mm across the state, with some areas potentially receiving up to 80 mm. Chief Superintendent Sonya Oyston of the NSW State Emergency Service has urged caution, advising residents against traversing flooded roads.
In Melbourne, temperatures are projected to decrease from 23°C on Tuesday to around 14°C by Thursday. Meanwhile, Hobart and Adelaide will also experience cooler temperatures, with Hobart expecting up to 300 mm of snow in the coming days.
As conditions improve late Friday, warmer weather is anticipated just in time for the AFL Grand Final, although additional showers may return early next week.
