Weather Situation
A broad high pressure system over Victoria extends a ridge over New South Wales. The high is forecast to move over New South Wales today, and reach the northern Tasman Sea early Tuesday, turning the winds north to northwesterly. Winds will freshen ahead of a trough and cold front crossing the coastal waters during Wednesday and Thursday, driving west to southwesterly winds in its wake.
