As on predicted lines, South Coastal Tamil Nadu received heavy rainfall in the past 24 hours. The popular fishing port of Pamban received a downpour of 280mm rainfall, the heaviest of this season so far. Karaikal, a town of the Union Territory of Puducherry, also got lashed with heavy showers, amounting to 90mm of rainfall. The other places like Atiramapattinam and Tuticorin also registered moderate showers. All these four coastal stations have been thrashed by heavy rains for the last four days. The intense weather activity is likely to cease and at best, very light rain and drizzle is expected over the next three days.
The Cyclonic Circulation over the Comorin region and coupled with the north-south trough was the main trigger for this uptick in the weather activity. The circulation will be moving westward across the Maldives and equatorial parts. Also, there is a likelihood of a powerful weather system forming over the South Bay Of Bengal, during this week. Presently, a cyclonic circulation has come up over the South Andaman Sea. This will become more marked, move westward and evolve into a depression over the next 3-4 days.
The wind pattern over Sri Lanka and Coastal Tamil Nadu will be under the direct influence of this strong weather system. Northeasterly winds are likely to pick up along the coastline for the next 3-4 days. As this flow will be steered by the upcoming system, the weather activity will reduce to minimal, during this period. By 25th Nov 2024, the system may develop into a storm and get positioned over the Southwest Bay of Bengal. The coastline of Tamil Nadu will once again come within the area of influence of the storm. Fresh and intense weather activity will start again and the first half of the next week will be vulnerable to inclement weather conditions. The complete scenario will be under observation and reviewed. Threat of cyclone, if any, and its implications for the region will be shared at the earliest.
