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 supported 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.
