NOTES ON THE CYCLONE 
Bay and adjacent coast districts are usually very uniforin. 
Bearing these conditions in mind let us turn to the Daily 
"Weather Eeports for a few days preceding the 9th 
November. In these we find that on the 1st of the month 
the highest barometric pressure in India was 30-071 inches at 
Sibsagar, and the lowest 29'910 inches at Karwar ; on the 
2nd the highest and lowest were 30-076 at Sibsagar and 
29-927 at Colombo; and that fairly strong winds between 
north and east prevailed over most of India. By the 4th, 
however, the barometric gradient between north and south 
had decreased, and the weather throughout Madras was un- 
settled, with tolerably heavy rain. On the 5th a barometric 
minimum showed itself off the Coromandel Coast, and at 
Diamond Island the barometer was falling, with a brisk north- 
east wind and heavy rain. At Madras the barometer was 
oscillating considerably from day to day with, on the whole, 
a downward tendency. Next day's reports showed that 
these disturbed conditions were getting more strongly marked, 
and the minimum off the Coromandel Coast was better de- 
fined. On the 7th the Reporter was able to write : " A 
cyclonic storm of tolerably large d im ensions is approaching 
the Coromandel Coast, and is influencing the dii'ection of 
the winds over the whole of the Bay as well as in Central 
and Southern India." Information obtained from ofiicers of 
ships that had come from Colombo showed that in the south 
of the Bay there was still a strong south-westerly air cui-rent 
bringing into the Bay the large quantities of moist aii' which 
are necessary for the development of a cyclone. On the 7 th 
the barometer at Madi-as rose till about 4 p.m. when it began 
to fall rapidly. The Weather Report for the 8th — based 
on the 10 o'clock observations — stated that " the depression 
noted yesterday as existing over the Bay of Bengal off the 
Coromandel Coast has thus slightl}' intensified, and the centre 
of the storm has moved slowly towards the coast."
