The Southern Highlands Rural Fire Service is now dealing with three bushfires which are burning west of Lake Burragorang that have burnt out around 23,000 hectares.
All three fires are still uncontained and pushing further to the east due to the strong winds.
Heading into tomorrow there is the chance there maybe some spotfires which could start on the eastern side of the lake.
Inspector David Stimson says they're advising all of the communities from Hill Top right up to Warragamba to stay up to date and keep their bushfire survival plan on hand.
Residents in the northern part of the Wingecarribee will likely receive letters tomorrow, advising them of the situation.
