The sixth cyclone of the season was Erica . This revolving storm developed in an extensive low pressure area which had persisted off the Pilbara coast for some days. It travelled between Barrow Island and Onslow and then passed across the peninsula south of Learmonth to the eastern Indian Ocean where it decayed over tropical waters.
Erica was a storm of only moderate intensity but because of the location of its development it caused considerable concern though only minor damage resulted.
