The Bureau of Meteorology warns these winds have the potential to bring down trees and powerlines.
Emergency services are urging people to clean-up loose items around their properties, and reconsider marine activities such as boating or rock fishing.
The cold front behind the windy conditions will also bring additional snow falls to the alpine areas, with blizzard conditions possible.
Snow levels are expected to drop significantly on Saturday, with light falls possible in parts of the Monaro Country, Southern Tablelands, ACT and Central Tablelands. Although it's unlikely any snow that does fall will be deep or long lasting

Rain totals are not expected to be high in most areas but with many catchments near saturation river flooding is a risk, and a number of Flood Warnings are in place.
