Tropical cyclone activity was restricted to three cyclones, extending from 29 November to 19 February. There was no cyclone activity in the months of January, March or April. This unusual state of events was associated with much higher than normal mean pressures over Eastern Australia and with a tendency toward s the formation of a 500 mb trough "graveyard" over the Coral Sea area, where thickness patterns showed the absence of the usual w arm ridges, these having been displaced eastwards to the longitude of Fiji. Of the three storms only the first was a major cyclone; the others failed to reach maturity. Locations of outbreak were: Solomons Sea, western Coral Sea near Willis Island and eastern Arnhem Land. All three storms showed a predominant E or SE movement.
