Frontal deluge for South Australia, Victoria and Tasmania
A significant rain-bearing cold front, currently situated over the eastern parts of South Australia and western Victoria, is slowly making its way over the southeastern parts of the country, bringing the best June rainfall in decades to some stations.
By 9am on Wednesday, numerous stations across the West Coast, Mount Lofty Ranges, Adelaide, Mid North and Murraylands forecast districts of South Australia had received 30-60mm of rainfall, while falls of 15-25mm were recorded over the peninsulas.
Most of this rainfall fell in the early hours of Wednesday morning.
Mount Crawford's 45mm, Adelaide's 38mm at its Kent Town Station and Rosedale's 31mm accounted for the heaviest June rainfall in six years for these stations. The 29mm that fell at Karoonda was the heaviest June rainfall in 25 years, while Adelaide's West Terrace station's 40mm was its heaviest June rainfall in over 60 years.
Further east, stations across Victoria's Wimmera have received 20-30mm since 9am on Wednesday as the system slowly makes its way eastward. Nhil Airport (30mm), Horhsam Airport (22mm) and Longerenong (22mm) all have already recorded their heaviest June rainfall in at least six years, while Warracknabeal's 27mm so far has been its heaviest June rainfall in 14 years.
In addition to healthy rainfall totals, the system is bringing very strong winds across the southeast of the country. Wind gusts in excess of 100km/h have been recorded across the alps on Wednesday, while sustained winds of 50-60km/h have been recorded across Victoria. Severe weather warnings for damaging winds are in place for each district in Victoria and parts of the Snowy Mountains in New South Wales as a result.
The system is expected to bring further falls of 10-20mm across the remainder of Victoria and Tasmania during the rest of Wednesday and into early Thursday, before the front moves into the Tasman Sea and winds begin to ease over mainland Australia. However, strong winds in the wake of the system may still affect Tasmania, and more severe weather warnings could be issued.
