Fresh Low Pressure Area Likely: South India To Gear Up For Heavy Rains

Low pressure area is likely to form over Bay of Bengal(BoB), early next week. Remnant of an active weather system over Southeast Asian region is likely to make its way to BoB, shortly. Currently, a depression is marked over South Vietnam, South Laos, Southeast Thailand and neighboring West Pacific Ocean with a well marked broad cyclonic circulation over that area. This feature will move eastward across Thailand and Myanmar over the next 2days. Weakened cyclonic circulation of this depression is expected to hop across Arakan Coast and enter BoB on 16^thOctober.

Cyclonic circulation over extreme East-Central BoB will move over the central parts on 17^thOct. It is expected to consolidate further and turn in to a low pressure area over West-Central BoB on 18^thOctober. Looks like that the weather feature will remain parked over the sea for the subsequent 2-3 days, albeit gathering pace and force. It is likely to shift closer to the coastline of South Andhra Pradesh and North Tamil Nadu, during this period. It seems to be breaching the coastline and move inland on 22^ndOctober.

Central and Southern parts of Bay of Bengal and the Andaman Sea witness frequent cyclonic circulations as part of seasonal easterly systems, anytime after 15^th October. This is in anticipation of onset of Northeast Monsoon over South Peninsula. Such systems set the stage and paves way for the annual feature, exclusive to South India. States, down the coastline from Odisha to Tamil Nadu, across Andhra Pradesh will observe spike in the weather activity between 18^th and 20^th October.  However, the spread and intensity of weather will shoot between 21^st and 23^rd Oct, particularly so for South Coastal Andhra Pradesh and North Coastal Tamil Nadu. The weather activity will travel deep inland as well, covering interior parts of Andhra Pradesh, Tamil Nadu, Rayalaseema, South Interior Karnataka, Coastal Karnataka and Kerala.
