Northeast Monsoon has made its onset over some parts of South India. In last 24 hours, Chennai has witnessed scattered rainfall. These rains can be attributed to the cyclonic circulation which is persisting over Southwest Bay of Bengal off Tamil Nadu Coast. Moreover, easterly and north-easterly winds are prevailing over Coastal Andhra Pradesh and Tamil Nadu. We can expect some more scattered rains in next 2 days as well. Thereafter, rains are expected to be subdued over the city.
Generally, the arrival of Northeast Monsoon is around October 20, but this year it has been delayed a bit. The commencement of Monsoon is quite slow this time around, however due to a weather system which is developing over southeast Bay of Bengal near Malay Peninsula, rain intensity is expected to increase over northern parts of Tamil Nadu including Chennai by November 9.
Though Chennai has received good rains during Southwest Monsoon, but in the month of October the weather has remained almost dry. The prolonged dry spell over Chennai has finally come to an end.
From October 1 till October 30, actual rainfall received over the city of Chennai is 26.5 mm whereas normal rainfall for this time period is 252.7 mm. So in totality the rainfall has decreased to 90% below normal.
