During the next twenty-four hours, rapid movements were experienced in the 

 pressure translation. The high pressure, which was to the south-east, had 

 passed away to the Tasman Sea ; the antarctic low, after travelling 800 miles, 

 was now to the south of Portland (V^ictoria), and the anticyclone over West 

 Australia had expanded 1,200 miles eastward. One hundred and fifty-three 

 points at Mein was the only amount reported from Queensland, and 1 point 

 at Leeuwin, and 15 at Albany were the only I'ainfalls in West Australia; 

 otherwise, excepting for scattered cloud areas, the weather was fine throughout 

 the continent. Indications of monsoonal activity were ap])arent on the 25th 

 over Northern and West Australia, where unsettled and showery conditions 

 obtained, resulting for the most part in light i-ains over West Australia, and 

 moderate to heavy falls along the north coast of Queensland. The heaviest 

 amounts were 820 points at Geraldton, 300 at Mackay, and 40 at Cooktown. 

 Strong west to south-west winds also occurred in the south-east corner of the 

 continent and over Tasmania, with rough seas in Bass' Straits, 



During the early morning of the 26th a retrogressive movement took place 

 in the pressure systems over the continent, and an energetic flisturlmnce 

 appeared in the south-east' States, with a central barometric value of 29*4 

 inches in the M-est of Tasmania; These conditions during the next forty-eight 

 hours resulted in light consistent rain over the southern portion of West 

 Australia, also at scattered places in southern New South Wales and Victoria 

 and Tasmania, where rough seas and very strong winds obtained. On the 28th 

 fine, cool weather ruled over south-eastern districts of our State, particularly 

 on Central and Southern Tablelands. Blayney reported frost in the early 

 morning, and temperatures at Braid wood and Nimity belle fell as low as 30 

 degrees and 32 degrees respectively. Warmer conditions, however, occurred 

 in other parts of the State, the highest being 99 degrees at Mungindi, 95 

 degreps at Grafton, 94 degrees at Casino and Lismore, 93 degrees at Moree 

 and Clarence Heads, 92 degrees at Narrabri, and 90 degrees each at Brewarrina, 

 C'obar, and Bingara. 



The low pressure had remained practically stationary during the preceding 

 twenfy-four hours, and was still centrally situated to the south-east of 

 Tasmania, where it caused tierce squalls and gales, with high seas. The "high' 

 had lost some'*'hat in value, and moved in a north-east direction, whilst anothei' 

 low pressure appeared in West Australia, between Geraldton and Perth, and 

 was responsible for some light to moderate rainfall in the south-west districts. 



At 9 a.m. on the 30th, this disturbance was shown over the south-east 

 States, its centre occupying al)out the same position as the one on the 2Sth, 

 having travelled 1,600 utiles in forty-eight hours. The rear isobar of the 

 ''high" was also shuwn over the coastal districts of Queensland. Within 

 the following two days, light rainfall occurred all along the southern coast- 

 line of the continent, and northern p9,rts of our south-west slopes, southern 

 tablelands, coast, and exti-eme south-west districts. 



During the month rather mild temperatures ruled generally over the 



continent, l)ut a very interesting feature in connection with recent weather 



was the development und eri'atic track of the cyclonic storm which, at the
