Storms and heavy rainfall have made their mark over much of southwestern New South Wales as records tumble. A low and trough over the southeast brought the wet conditions. Lines of storms fired through the Upper Western down to the South Coast and up to the Central Tablelands. The storms were widespread, but two distinct lines appeared during Sunday, following small scale troughs. As a result, 'storm trains' set up. Namely, storms flowing over the same patch of land, one after the other. The result for some was exceptional rainfall that saw records fall. Wagga Wagga was a victim of one such storm train, taking 110mm in 24 hours and posting their highest total since at least 1942. The previous high of 104mm was registered in 1966. Across western NSW, rain rates in individual storms were huge too. 18mm in ten minutes was seen at Deniliquin, as were wind gusts up to 82km/h. The town took another 38mm in 24 hours to 9am today, bringing the March total to 126mm, their highest for any month in at least 12 years. Some other soggy facts: - Hail was reported at Hillston and White Cliffs - Corowa hit 73mm in 24 hours, their sixth highest on record and wettest in March in 120 years.
