Central and Southern Australian Will Experience Strong Winds, Cooling and Rainfall

From October 21 to 23, influenced by the eastward movement of an upper-level trough, a weather pattern characterized by strong winds, cooling, and rainfall will develop from west to east across central and southern Australia. Some areas will experience a temperature drop of 8 to 12°C, with localized exceeding 14°C (Figure 1). This will be accompanied by winds of 5 to 6 on the Beaufort scale, with gusts reaching 7 to 8, and locally as high as 9 to 10 (Figure 2). The southern and southeastern coastal regions of Australia will see light to moderate rain, with localized heavy downpours (Figure 3). Precautions are advised against the adverse impacts of these strong winds, cooling, and rainfall on local power transmission and maritime transportation.
