Weather Situation
Northerly winds will persist about Sydney Waters as a high pressure ridge extends across the region, strengthening further on Thursday. Following this, a cold front and its associated trough are forecast to move across the NSW from Friday through early Saturday, bringing a fresh and gusty southerly wind change to Sydney Waters in its wake. Winds will tend northerly again from Sunday as another high pressure system moves into the Tasman Sea.
