IMD issues red alert for several districts of Tamil Nadu, Puducherry . on Nov. 11

The Indian Meteorological Service issued a red alert on Nov. 11 for several districts of Tamil Nadu, including Chennai, Tiruvallur, Kallakurichi, Salem, Vellore, Tirupattur, Ranipet, Thiruvannamalai and Puducherry.

Thunderstorms with heavy to very heavy rainfall are expected in some places, the IMD warned on Wednesday.

“There is now widespread rainfall in Tamil Nadu. After 8pm it increased, especially in the northern regions,” a weather department official here told PTI. Announcing the expected formation of the depression, the IMD bulletin said the well-marked low pressure area over central parts of the southern Bay of Bengal was moving west-northwestward, concentrating into a depression Wednesday night.

It was about 430 km east-southeast of Chennai and 420 km east-southeast of Puducherry. “It is very likely to move west-northwest and reach the north coast of Tamil Nadu in the early morning of 11 November 2021. Thereafter, it is likely to continue to move west-northwestwards and into northern Tamil Nadu and the adjacent south coast of Andhra Pradesh between Karaikal and Sriharikota close to the north of Puducherry by the evening of November 11, 2021.”

The IMD warned of light to moderate, heavy, very heavy and extremely heavy rainfall in several areas and isolated places. Such regions are covered with the northern coast of Tamil Nadu, Puducherry, northern TN, the southern coast of Andhra Pradesh, Rayalaseema and southern Karnataka.

The low pressure area on November 9 over the southeastern Bay of Bengal was well marked Wednesday morning. The weather system is expected to bring rain in Tamil Nadu in the next two days.

Rainfall is expected to be scattered, heavy, very heavy and extremely heavy in certain regions and light to moderate in most other places.

On Tuesday, there was a decrease in rainfall here and nearby northern regions. However, the Cauvery Delta regions of Tamil Nadu and Karaikkal (Puducherry) witnessed very heavy showers. Nagapattinam led the list with 31 CM, followed by Karaikkal (29 CM) and Vedaranyam (25 CM).

Other delta areas, including Tiruvarur, Thanjavur, Mannargudi, Mayiladuthurai and Pattukottai, also experienced heavy rainfall.
