The normal season of Northeast Monsoon is considered to be from the month of October to December. However, Northeast Monsoon commenced late and arrived by October 30. Moreover, most of the October almost remained dry.
During that time, two weather systems developed over Northeast Bay of Bengal. Out of the two, one intensified into a cyclone named Kyant moving along the Andhra Pradesh and Odisha coast. Though it failed to give significant rains over the region.
The second weather system also intensified into a depression giving good rains over Tamil Nadu and Andhra Pradesh Coast for a couple of days. Since then, easterly winds are strong but on and off scattered rains are continuing over Tamil Nadu and Kerala.
As of now, a feeble cyclonic circulation is seen over north Kerala and adjoining areas and a trough is extending from Konkan coast to south Kerala. Due to this, light to moderate showers at many places may occur over coastal Karnataka and south interior Karnataka for next couple of days.
Thereafter, rain will again decrease over entire southern peninsula. Though on and off rains are still expected to continue over Tamil Nadu and Kerala but these rains will not be sufficient to reduce the ongoing rain deficiency which is at present very high.
In a nutshell, it can be concluded that drought-like conditions are expected to continue over entire south India due to weak Northeast Monsoon.
