The pressure distribution on the 2-l:th and 25th was rather unusual, for 

 the depression by 9 a.m. on th<^ former day had assumed abnormal proportions 

 and covered the area south of lines joinin<^ Perth, Alice Springs, and Mel- 

 bourne, whilst over portions of Northern Australia, monsoonal activity was 

 in evidence between the Gulf of Cai-pentaria, l^oulia, and Alice Springs. 



Strong dusty northerly winds, with tierce squalls, occurred over South 

 Australia and on the sliores of the Great Bight, and rising temperatures 

 together with falling barometers, were reported from all the States but West 

 Australia. In tlie latter State showery weather, with south-west gales and 

 rough to high seas obtained on the South Coast. 



Tl:.' highest and lowest temperatures recorded over the various subdivision.^ 

 of the State between the 19th and 25th were as follow : — 



Western Division ... 

 North-western Slopes 

 Central-western Plains 

 Riverina

Between the 2Gth and 30th, two high and two low pressure systems travelled 

 across the continent. The first " high," represented by only one isobar, was 

 shown on the 26th over New South Wales and the South Island of New 

 Zealand, and was associated with fine, clear, and quiescent weather conditions. 

 The "low" which appeared on that day, was situated over the southern 

 districts of tlie continent, from Esperance to the Great Bight, ami controlled 

 fresh to strong northerly winds for the most part, but strong south-westei'lies 

 on the south-western seaboard, and a strong westerly gale at Eddystone in 

 Tasmania. Moderate to rough seas also occurred between the Leeuwin and 

 Wilson's Promontory. By the 28th, the incipient high pressure had passed 

 off the main land, but the i-ear isobars of the depression were shown running 

 along the coastal districts from Clarence Heads to Hobart ; and showery 

 weather obtained south from Jervis Bay. In proximity to the "low" was the 

 advance portion of the second anticyclone, on the north east side of which 

 had appeared a I'ather pronounced depression. During the night of the 28th, 

 or early on the morning of the 29th, as the result of this distribution, some 



,sevex'e .squalls and rain, with scattered thunderstorms, were experienced along 

 the coastal and north-eastern districts of New South Wales, as also in south- 

 eastern parts of Queensland. The jjatli of the centre of the high pressure 



■ which had attained the barometric value of 30'47 inches, was well to the 

 south of the continent. This circumstance assisted in the development of 

 severe wind and sea conditions on our seaboard.
