Weather Situation
A high centred over Victoria extends a ridge across most of the state while a trough lies off the the north coast bringing south to southeasterly winds to NSW waters. Over tomorrow the coastal trough will decay while the high moves over the Tasman bringing southeasterly winds to the northern part of the coast and northerly winds to the southern part of the coast. Over Monday winds will tend north to northeasterly as the high moves further east before a southwesterly change associated with a trough makes its way up the coast Tuesday, with winds tending strong southwesterly on Wednesday as the trough moves east and develops into a deep low pressure system.
