Australia Braces for Extreme Weather Conditions This Weekend

Australia is set to experience a mix of extreme weather conditions this weekend, with heavy rain expected for the eastern seaboard, a possible late-season cyclone in the Gulf of Carpentaria, frosty nights in southern states, and record-breaking unseasonable warmth in Western Australia.

The Bureau of Meteorology predicts that the eastern states will see a broad rainband bringing heavy showers, with the potential for minor flooding. Sydney temperatures will reach just 23°C on Saturday, down from 25°C the previous week, with a 90% chance of 3-15mm of rain. Coastal areas may face winds up to 45km/h.

Meanwhile, a tropical low in the Arafura Sea threatens to develop into a cyclone, though it is expected to track away from the mainland. This late-season cyclone development is an uncommon occurrence for this time of year.

In the south, overnight temperatures will drop to single digits, with Melbourne and Adelaide experiencing their coldest weather so far this year. Melbourne will see a high of only 18°C on Saturday amid cloudy conditions, after experiencing a maximum of 28°C just a few weeks earlier. Canberra and Hobart will hover around 10°C on Saturday morning, warming to no more than 20°C.

Brisbane is forecast to receive up to 15mm of rain in the afternoon and evening, despite starting the day at 20°C.

Why this matters: The extreme and varied weather conditions across Australia this weekend highlight the country's vulnerability to climate change impacts. The unseasonable warmth in Western Australia and potential for a late-season cyclone raise concerns about shifting weather patterns and their effects on communities and ecosystems.

In sharp contrast to the rest of the country, Western Australia continues to experience an exceptionally warm and dry autumn. Perth is expected to see sunny and warm conditions with temperatures around 30°C, while the city has received just 1mm of rain this month, well below the April average. Perth's temperatures are averaging 5°C above normal for this time of year.

The Bureau of Meteorology advises residents in affected areas to stay informed about local weather conditions, follow the advice of emergency services, and take necessary precautions to ensure their safety during this period of extreme weather. As one meteorologist noted, "This weekend's weather is a reminder of the diverse and challenging conditions that Australia can face, and the importance of being prepared for all eventualities."
