A high pressure system over the central Tasman Sea is maintaining a ridge into New South Wales and directing southeast to northeasterly winds along the coast. Northeasterly winds are expected to increase during Wednesday as a trough approaches from the west. This trough is forecast to bring a southerly change to the Sydney coast later Thursday. Another high is forecast to move in behind the trough during Friday as the low moves rapidly away to the east, and this high should remain the dominant feature in the region through the weekend.
