Australia's Skies Glow Orange as Powerful Winds Pull Dust From Parched Land

The skies of southern Australia turned a hazy orange this week as a dust storm reduced visibility, prompting health warnings and creating scenes reminiscent of an apocalyptic movie, rather than a late-autumn day. The storm was driven by powerful winds carrying dust from the drought-stricken ground of South Australia into the neighboring states of Victoria and New South Wales on Monday and Tuesday. Skies were smothered in major cities including Melbourne, Canberra and Sydney. The Bureau of Meteorology issued a severe weather update early Monday as a very strong cold front moved in from the south and reached the mainland of southern Australia on Monday morning. By Monday afternoon, wind gusts had reached over 78 miles per hour in parts of South Australia. Wind alerts extended across parts of South Australia, Victoria and New South Wales, warning that strong winds might lead to falling trees and branches, as well as dust and reduced visibility. The dust storm is a result of very dry land from longer-term weather conditions across Australia. Since early 2023, Western Australia, South Australia, Victoria and Tasmania have seen some of their lowest rainfall since 1900, the Bureau of Meteorology reported in early May. Slow-moving high-pressure systems have led to unusually warm and dry conditions — a continuation of weather patterns seen through much of 2024, the report said. But not everywhere is dry: Other parts of southeastern Australia were battered by relentless rounds of rain this month, and a part of New South Wales received roughly four months' worth of rain in three days. At least four people were killed, including a man who was found in a car trapped in floodwaters. Entire towns saw homes destroyed by floodwaters, and livestock were swept away. In Sydney, water on rail tracks affected some train lines, including services to the airport. Sydney Airport was also forced to shut down two of its three runways. As the dust this week traveled east, air quality deteriorated. Air quality ratings of very poor to extremely poor were issued on Monday afternoon for northwestern parts of Victoria and southwestern areas of New South Wales. By Tuesday morning, the dust had reached eastern parts of New South Wales, prompting extremely poor air quality ratings there as well. The health agency in New South Wales warned of high levels of particulate matter during the dust storms, specifically PM10 particles, which are the most common type during bush fires and dust storms, and are small enough to enter the lungs and pose serious health risks. A spokesperson for NSW Health said in a statement on Tuesday that the risk to health was likely to be low, as conditions were expected to improve. However, forecasters warn that the continued dry conditions will most likely lead to more of these dust storms, as soil becomes drier and more exposed to the winds. According to the Bureau of Meteorology's long-range forecast, rainfall is expected to remain below average through July in parts of the southwest, southeast and east. Australia is no stranger to dust storms, though the Bureau of Meteorology said they are more common in spring because of the cold fronts that move over Australia's southeast and interior. In September 2009, a similar combination of drought and winds clogged Sydney and other parts of the east coast with a haze so thick that flights were diverted.

Hazardous dust storm turns sky eerie orange as residents urged to ‘stay inside'

Parts of Australia have been hit by a hazardous dust storm which has turned the sky completely orange, with the public warned to stay inside. Footage shared by the District Council of Orroroo Carrieton shows a fierce storm raging across a town in South Australia, with trees and signs shaking wildly. 'Stay safe everyone, stay off the roads and inside if you possibly can', the council said online. The Bureau of Meteorology has issued a severe weather warning for most of the state. The storm has also spread to New South Wales, with the state's health agency issuing alerts for very poor air quality.

New South Wales battered by hazardous dust storm in wake of record floods

Australians in New South Wales are facing yet another extreme weather challenge even as thousands are still reeling from days of storms and unprecedented flooding. Massive dust clouds blanketed parts of the state, including the capital of Sydney, on Tuesday, creating conditions which experts warn are hazardous to health. Authorities warned of 'extremely poor' air quality in some suburbs, with PM10 particle levels exceeding 600 – far above the 'good' threshold of 40, according to environmental standards. PM10 refers to particles with a diameter of 10 micrometres or fewer, which are 'small enough to pass through the throat and nose and enter the lungs', according to NSW Health. Short-term exposure to them can exacerbate pre-existing health conditions such as asthma and lung or heart disease. Particles in the air may include dust, sea salt, and by-products from fires, vehicles and industrial sources, according to Air Quality NSW. 'These particles can pass into the lungs,' the agency said, adding they can trigger breathing difficulties, eye and throat irritation, or worsen chronic bronchitis and asthma. The dust storm originated in South Australia and swept across Victoria, reducing visibility to as little as 300 metres (1,000 feet) before moving into central and southeastern New South Wales, according to the Australian Broadcasting Corporation.
