Tasmania. It looks as if the low pressure had retreated and its 

 western parts forced their way north. What probably did take 

 place was that a storm centre south of the Australian Bight and 

 indicated by the northerly winds in Chart 39, had in the interval 

 surged northwards on to the west coast of Victoria, bringing with 

 it all its antarctic energy and severe cold. This view is sup- 

 ported by the fact that there was in the twenty-four hours but 

 little change in the New Zealand isobars, and further by the 

 upward tilting of the eastern part of the anticyclone caused by 

 the northing of the antarctic storm, and lastly by the blizzard- 

 like cold which was so marked a feature of this storm.
