Wilcannia has received the third heaviest 24-hour rainfall total since records began back in 1879, causing the Darling River to rise. Located in the Upper Western district of NSW, Wilcannia picked up 118mm of rain in the 24hrs to 9am this morning, making it their wettest March day on record and more than five times the monthly average. The extreme weather has meant that what is typically one of the driest places in Australia was the wettest for a brief period, as it was the only place in the country to exceed 100mm. This latest rain comes on the back of previous falls, bringing the town's March total to 166mm on the third day of the month. With rain continuing today, there is a chance that this month will be Wilcannia's wettest on record, which currently stands at 258mm. The Darling River was already at a Minor Flood level before last night's rain. The latest falls have bumped this level to Moderate, with the river height currently pushing 10 metres. The heavy rainfall is part of a broad rain-band that has stretched from western NT, through SA and into NSW and VIC over the past week. The rain-band has been caused by a low pressure trough which has fed huge amounts tropical moisture from the north of the country into the southeast. Rain is expected to keep falling in Wilcannia today before the trough moves further east, bringing the heaviest rainfall to central NSW tomorrow.
