The Nancowry and Port Blair observations prove that strong steady 

 south-westerly winds continued to blow in that part of the Bay. These 

 winds were also extending to Diamond Island. The average wind 

 velocity during the past 24 hours at that station was 10 miles, and for 

 the previous day had been 8 miles per hour. The sea was also reported 

 to be rising. Hence it is certain that the vigorous current indicated by 

 the strong winds at Port Blair on the 25th was steadily advancing up the 

 east of the Bay, and that its front was off the West Burmese coast on the 

 morning of the 26th. The Pemba, which left Rangoon at 10 A. m., had 

 south-westerly winds of force 5 with frequent rain squalls, as she ad- 

 vanced westwards in the Martaban Gulf to the south of the Burmese coast. 



It is almost certain that this strong current was giving heavy rain 

 over a portion of the north-east of the Bay in the neighbourhood of the 

 Burmese and AiTacan coasts. The direct evidence of this does not appear 

 in the extracts from the logs of the vessels given above, but it will 

 appear in those for the 27tli. It is, however, indicated by the large rain- 

 fall at Diamond Island and other stations in South Burmah and in 

 Arracan. 



For the present wc shall accept it as almost certain that in the front
