The India Meteorological Department (IMD) has issued a cyclone alert for the Bay of Bengal as it predicts the formation of a low-pressure area in the southeastern part of the Bay, set to develop around November 23. This system, triggered by a cyclonic circulation near Sumatra and the adjoining South Andaman Sea, is expected to bring heavy rainfall and potential cyclonic weather to southern India, particularly Tamil Nadu and Andhra Pradesh.
The IMD has forecast the system will likely move west-northwestwards, intensifying into a depression over the central parts of the south Bay of Bengal within two days. The weather department has also highlighted the presence of another cyclonic circulation over the Comorin area, further fueling concerns about adverse weather conditions in the region.
Rainfall Forecast Across Affected Areas
The IMD has predicted light to moderate rainfall, thunderstorms, and lightning in several parts of southern India. Heavy rainfall is expected to hit Tamil Nadu, Andhra Pradesh, and neighboring regions. Isolated heavy rain is forecast for south Tamil Nadu on November 21 and 26, with similar conditions in Coastal Andhra Pradesh and Yanam on November 26 and 27.
Tamil Nadu and Andhra Pradesh:
- Isolated heavy rainfall is expected in south Tamil Nadu on November 21 and 26. Coastal Andhra Pradesh and Yanam will see heavy rainfall on November 26 and 27.
- Additional rainfall is predicted for Kerala and Mahe on November 21, 25, and 27, along with the Andaman and Nicobar Islands.
- The northeastern states, including Assam, Meghalaya, and Nagaland, are also expected to receive light to moderate rain from November 21 to 22.
Ongoing Heavy Rains in Tamil Nadu
Parts of Tamil Nadu have already experienced intense rainfall, leading to severe flooding and waterlogging. Thoothukudi city, in particular, has seen significant disruptions. Urban areas such as Rajagopal Nagar, Pushpa Nagar, and Raju Nagar have been heavily waterlogged, with submerged houses making headlines across social media.
Since the northeast monsoon began in October, large swathes of northern and delta regions of Tamil Nadu, including Chennai, Chengalpattu, and Kanchipuram, have received substantial rainfall. The delta districts of Thanjavur, Nagapattinam, Tiruvarur, and Mayiladuthurai have been particularly affected, with waterlogged roads and disruptions to daily life.
The IMD has warned that this weather system will continue to bring rainfall, along with thunderstorms and lightning, to Tamil Nadu, Andhra Pradesh, and nearby regions over the next several days.
Impact on Local Communities
The continuous heavy rainfall has severely affected local infrastructure, including transportation and power supply in many areas of Tamil Nadu. As the cyclone intensifies, authorities have urged residents to stay alert and follow safety guidelines, with the possibility of more localized flooding.
The IMD’s forecast of isolated heavy rainfall highlights the need for vigilance, especially as the cyclone’s path evolves. Both state and central authorities are monitoring the situation closely, with relief efforts in place to address the immediate impact on affected communities.
Conclusion
With the IMD’s cyclone alert in place and expected heavy rainfall, residents of Tamil Nadu, Andhra Pradesh, and nearby regions should be prepared for potential disruptions. Authorities have emphasized the importance of staying informed and following weather updates closely to minimize the impact of the impending weather system.
