Parched paddocks have received a thorough soaking in many regions where grain growers and livestock producers were desperate for rain.

Weather forecasting service Weatherzone noted a significant rain-bearing cold front, currently situated over the eastern parts of South Australia and western Victoria, has delivered some of the best June rainfall in decades.

Weatherzone said by 9am today (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 this morning. Further east, weather stations across Victoria's Wimmera have received 20-30mm since 9am today as the system slowly made its way eastward.

Nhill Airport (30mm), Horsham 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.
