The northeast monsoon is heading towards its end in South India as there is a very rare possibility of the emergence of any significant weather system in the Bay of Bengal any time soon. Rain has already reduced in coastal areas of Tamil Nadu and further, there shall be no rainfall in significant amounts in the coming few days.Tamil Nadu receives 90 percent of its rain from the northeast monsoon but this year, until now, the rainfall figures have proven to be deficient in the state.
According to our forecast, the northeast monsoon will bring some rain in South India throughout the remaining days of December but that will depend on some easterly winds from the Bay of Bengal. However, this may not be enough to cover up the deficit faced by the state.
Northeast monsoon rain has remained excessive in just one out of the five regions in South India (1st October till 11th December). Coastal Andhra Pradesh recorded 44 per cent more rain than the average of 315 mm. It has received 453.9 mm of rain during this period. Four other regions namely Rayalaseema, south interior Karnataka, Tamil Nadu and Puducherry have witnessed a deficit monsoon.
The northeast monsoon has been normal in Kerala which received 426.9 mm of rain against the average of 465.6 mm in the period from 1st October till 11th December.
