The reason behind the continuation of rain in South India is a weather system which is brewing in the proximity of the Bay of Bengal. The current weather system in the Bay is expected to intensify to become more prominent, affecting the weather condition over the entire peninsular India, including south interior Karnataka, Kerala and Rayalseema.
However, the feeble tropical storm expected is no way similar to Phailin, which witnessed strong winds and torrential rains. Another difference between Phailin and the present weather system will be their paths. This system will continue moving westward and reach Tamil Nadu coast by late night. Phailin, on the other hand, had moved north-westwards from its place of origination in the southeast Bay of Bengal and reached Odisha and north coastal Andhra Pradesh.
With these weather systems, Northeast Monsoon in South India will get back on track with enough rain to possibly mitigate the deficiency in the first half of November.
