The remnants of Cyclone Kirrily are expected to bring heavy rainfall and flash floods to parts of Australia’s most populous state, NSW, this week. The Bureau of Meterological warned that the extreme weather conditions could affect the region’s Upper Western region.
According to the weather agency, the ex-tropical cyclone was located near Innamincka in South Australia. It’s expected to move toward the NSW Upper Western district sometime this morning. It’s then expected to move southeast and reach central regions of the state later in the evening.

The agency noted that the western and eastern parts of the NSW Upper Western region could receive heavy rainfall starting Monday morning. It could also cause flash flooding. It’s estimated that up to 80mm could fall within six hours. On the other hand, 24-hour totals of up to 100mm could occur.
Intense rainfall that could lead to dangerous flash flooding is also possible in some areas, particularly near the low. The agency noted that powerful winds with gusts of up to 90 kilometers per hour could occur in some parts of the state, such as Bourke, White Cliffs, and Tibooburra. The agency predicted that the remnants of the storm will affect Sydney and Canberra by Tuesday.
According to the bureau, Canberra is expected to receive heavy rainfall. As the ex-tropical cyclone moves south of Sydney, it’s expected to bring moderate or light rain to the city’s periphery. However, it’s expected to bring heavier falls over the next couple of days along the NSW coast from Wollongong to the Victorian border. Weatherzone also warned that the storm’s damaging winds and dangerous flash flooding could occur.
According to the weather service, the remnants of Cyclone Kirrily will bring heavy rainfall to parts of NSW and eastern Victoria on Monday. It noted that the wild weather system will be driven by the abundance of tropical moisture.
The storm is expected to affect southeastern NSW from Tuesday to Wednesday, and it’s threatening areas such as Canberra and Sydney. The NSW State Emergency Service urged residents to avoid driving through floodwaters and to stay at least 8 meters away from downed power lines.
In addition, the SES also urged residents to avoid driving through floodwaters and to stay away from storm drains and creeks. It noted that people trapped by flash flooding should seek higher ground. Also, be aware that the run-off from heavy rainfall in bushfire-affected areas can behave differently. It can contain objects such as rocks, soil, and ash.
After bushfires, heavy rainfall can cause the ground to become soft and heavy, which could lead to landslides. In Queensland, the Bureau of Meteorology has issued flood warnings for several rivers, including the Cloncurry, Moonie, Balonne, and Flinders. The state is still reeling from Cyclone Kirrily’s effects, which hit the north on January 25. It caused severe damage to various areas, including Townsville.
Residents of the Kynuna community in the McKinlay Shire were evacuated to Cloncurry on January 29. In southeast Queensland, some people in the Moreton Bay Council were forced to relocate after their homes were submerged by floodwaters on January 30.
