The observations of the 1st indicate that the barometric depression 

 moved during that day in the same direction as hitherto and at a rate of 

 about 15 miles per hour. The westward motion of the depression had caused 

 a fall of nearly two-tenths of an inch in the barometer over the greater 

 part of the Central Provinces, and a general, although a slight, decrease 

 over the whole of the Peninsula and Bombay. In Bengal, the rapid recovery 

 in progress on the 30th continued. A rapid rise had also occurred over 

 the Punjab and the western districts of the North Western Provinces, due 

 to some other and independent action. A very distinct circula.tion of the 

 air was shown round the centre of depression. In the mid-Gangetic 

 valley, the winds had drawn round to north-east, and, over the western 

 portions of the Central Provinces, they were blowing from north-west. 

 Moderately strong winds continued at the Head of the Bay and in South 

 Bengal. No change of importance had occurred in the wind directions 

 over Bombay and the south of the Peninsula. Strong west winds pre- 

 vailed along the Bombay coast, where, however, little or no rain was 

 falling. Local winds obtained in the Punjab. The sky was less clouded, 

 the weather finer, and rainfall less in amount over the Gangetic delta 

 and valley. The depression was, however, giving very heavy rain to the 

 Central Provinces, where the sky was overcast. Over the remainder of 

 the country, the weather was of the usual monsoon character. 



The storm had advanced through the Clihatisgarh division of the 

 Central Provinces (which includes the Sambalpore, Bilaspore, and llaiporo 

 districts), and was now passing through the Jubbulpore and Nagpur 

 divisions.
