South to southwesterly winds as a high pressure system centred over the state moves east into the Tasman Sea. A weak trough developing over the southern waters today brings northeasterly winds to the southern coasts. North to northwesterly winds redevelop across the state's coast ahead of a vigorous cold front crossing the waters late Saturday into Sunday.
