Weather Situation

A strong high pressure system south of the Bight is slowly moving east, extending a ridge across southeastern Australia and establishing a southerly flow over the coastal waters. This ridge is expected be the dominant synoptic feature over the following few days. During Thursday a low pressure trough will develop over northeastern New South Wales as the high moves east across the southern Tasman Sea and the ridge weakens. The trough is expected to move offshore during Friday and deepen before moving away from the coast on Sunday.
