Some parts of Victoria and South Australia have just recorded their strongest wind in years and it is only going to get windier. By early Monday afternoon northwesterlies had reached 104km/h at Aireys Inlet, on Victoria's South West coast, the windiest it has been at that location since winter 2009. In South Australia, it hasn't been as windy, but windy enough near the coasts earlier today to have knocked down the wall of house in Port MacDonnell, near Mt Gambier. Severe weather warnings have been issued for parts of SA, Victoria, Tasmania and New South Wales as an intense low swings a strong cold front across the region tonight and tomorrow. Wind is yet to peak, but it will most likely do so in SA and Tasmania by early this evening, in Victoria and southern NSW tonight and central NSW, including Sydney tomorrow. Wind is likely to exceed 100km/h on the coasts, hills and mountains in each state and get as strong as 120-to-130km/h on the highlands. Significant damage is on the cards, including downed trees and powerlines. For many areas this will be the strongest wind for the year so far. For some it is likely to be the strongest in several years.
