Weather Situation

A complex low pressure system, with multiple centres, lies off the New South Wales coast and will move away to the east today. Vigorous southerly winds on the western side of the low are expected to gradually ease during the day as the low loses influence and a high pressure ridge approaches from the west. This ridge is forecast to be slow-moving and remain the dominant feature in the region through the weekend. The next significant frontal system looks set to cross the coast during Monday and Tuesday.
