Australia is bracing for extreme weather conditions this weekend, with a severe heatwave set to impact the southern states, while intense rainfall threatens to cause major flooding in Far North Queensland. According to the Bureau of Meteorology (BoM), temperatures in some regions will soar up to 14°C above average, while parts of Queensland could receive up to 500 mm of rain in a single day.
Heatwave Conditions to Grip South-Eastern Australia
The heatwave, driven by an accumulation of hot air over Western Australia’s Pilbara region, is expected to push temperatures significantly higher across South Australia, Victoria, and Tasmania. Cities including Melbourne, Adelaide, and Hobart will experience consecutive days of extreme heat, with temperatures reaching 38-39°C in some areas.
Forecasted temperatures for major cities include:
- Melbourne: 31°C on Saturday, peaking at 37-38°C on Sunday and Monday.
- Adelaide: 36°C on Saturday, rising to 38-39°C by Monday.
- Hobart: A cooler start to the weekend, but climbing to 34°C on Tuesday.
- Perth: Milder temperatures over the weekend, but expected to hit 40°C by midweek.
The prolonged heatwave is exacerbated by the absence of cyclones in Western Australia and a delayed monsoon season, which have allowed temperatures to build up over time. According to BoM senior meteorologist Dean Narramore, this pattern is leading to an extended period of high temperatures, particularly across Western Australia’s Gascoyne region, where temperatures could reach 47°C.
High Fire Danger and Extreme Heat Risks
Authorities have warned of high fire danger across multiple states due to the combination of extreme heat and dry conditions. While strong winds are not currently expected, reducing the immediate bushfire risk, the South Australian Country Fire Service has alerted residents about smoke from Victorian bushfires moving westward.
Additionally, the intense heat poses health risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing conditions. The BoM urges residents to stay hydrated, avoid strenuous outdoor activities, and check on at-risk individuals.
Tropical Low Brings Major Flood Risk to Far North Queensland
While the southern states face extreme heat, Far North Queensland is preparing for significant flooding as a tropical low nears the coast. The system is forecast to bring widespread rainfall of 200-300 mm per day, with isolated falls reaching up to 500 mm over the weekend.
The heaviest rainfall is expected between Innisfail and Ayr, though flooding risks extend beyond these areas due to already saturated catchments. Mr. Narramore warns that the situation could worsen, stating:
“We’re likely to see quite a bit of flooding this weekend into early next week.”
Although the tropical low is unlikely to develop into a cyclone, its slow movement will prolong the heavy rain event, increasing the likelihood of flash flooding. Flood preparations are already underway, with authorities advising residents to monitor weather updates and prepare for possible evacuations.
Uncertain Outlook for Western Australia’s Tropical Systems
Meanwhile, meteorologists are also tracking multiple tropical lows across northern Australia, including two systems over Western Australian waters. At least one of these lows has the potential to develop into a cyclone in the coming days, though it currently poses no immediate threat to the mainland.
