At 9 a.m. on the 19th, an e.xtensive and eneigetic antarctic disturbance 

 covered the south-eastern Sta'es, and during the following forty-eight hours 

 was respon.sible for very stormy- conditions o\er a gretxt; area. The winds in 

 various districts reached the force of fresh to strong gales, and light to heavy 

 rainfall, associated with hail, was experienced almost genei-aliy east from the 

 Darling. 



As the depression worked eastwai'd, cold conditions set in, and many 

 places reported niinimum temperatui-es below the freezing-point. Snow also 

 occurred at scattered places on the highlands. In th(> city a westerly gale 

 with strong squalls commenced at 5 a.m. on the 20th, one of the squalls 

 registering a velocity of 55 miles per hour. 



By the 22nd the disturbance had practically passed off the seaboard to the 

 Tasman Sea, and although further light to moderate rainfall, with fresh to 

 strong westerly winds, still ]iersisted over Victoria and Tasmania, yet in 

 New South Wales fine weather obtained generally. 

 - At 9 a.m. on the following day, the eastern half of the continent was under 

 anticyclonic control, but the high jiressure was perceptibly weakening daily, 

 having lost three-tenths of an inch in central barometi'ic value since the 19th, 

 thus giving inducement to the I'ather rapid ad^"ancement of another depression, 

 "vthich, between 9 a.m. on the 22nd and 23rd, had travelled 900 miles eastward.
