During the 1960/61 season, cyclonic activity along the northern and western coasts of Western Australia and over adjacent waters was very marked, being almost constant from late December 1960 until early March 1961. During this period, a number of major cyclones caused damage and severe flooding in the northern parts of the State, and were responsible for consistent heat wave conditions, accompanied by disast rous forest and scrub fires, in the southern parts. The depressions are classified into three types according to the diameter of the area affected by the winds of gale force. The depressions are listed and catalogued. Finally each depression is discussed in detail.
Perth Staff of Divisional Office (Fri,) studied this question.
