A low system is currently heading towards the east coast of NSW with the Sydney-Illawarra region due to bear the brunt of the high winds and rainfall. It is hard to predict just how much rain will fall, but the NSW Bureau of Meteorology is predicting up to 200 ml in some parts of the region, with the possibility of localised flooding. Tess spoke to Anita Pyne from the Bureau, who gave a full prediction of the system change.
