As we've been announcing for the past two days, fierce winds are battering the southeast of the country, with some locations registering their highest wind gusts in one to three years. The culprit, a strong low-pressure system now moving east across the Tasman Sea. This system caused significant and widespread damaging winds across parts of southern SA yesterday and it will continue to bring wild winds to parts of VIC and eastern NSW until early Sunday morning, including populated areas of NSW and the ACT. The system has also delivered welcome snowfalls to alpine regions, with at least 30 cm of snow accumulating overnight at the NSW and VIC resorts.

Winds will gradually ease to fresh (strong at times) after dawn on Sunday as the low moves further east and a high pressure system takes over.
