Bay of Bengal Low Pressure November 13: IMD Issues Tamil Nadu Rain Alert and Fishermen Warning

The formation of a new low-pressure area over the Bay of Bengal has drawn attention as the Northeast Monsoon continues to influence weather conditions across Tamil Nadu.

According to the IMD, an upper-air cyclonic circulation over the South Andaman Sea and adjoining areas contributed to the development of the system. The low-pressure area formed over the Southeast Bay of Bengal around 5:30 AM on Friday, November 13.

The weather system is expected to move northwestwards over the next few days and gradually gain strength.

Low Pressure Likely to Intensify into a Depression by November 15

The IMD has forecast gradual intensification of the newly formed low-pressure area.

The expected development is as follows:

November 13: Low-pressure area formed over the Southeast Bay of Bengal.

November 14: Likely to intensify into a well-marked low-pressure area.

November 15: Expected to strengthen into a depression over the central parts of the South Bay of Bengal.

The system`s movement and intensity will be closely monitored by the weather department as it progresses northwestwards.

IMD Issues Fishermen Warning for Bay of Bengal

Following the formation of the low-pressure area, the IMD has issued warnings for fishermen operating in the Bay of Bengal and adjoining sea regions.

Fishermen have been advised not to venture into the following areas:

- Andaman Sea and Southeast Bay of Bengal on November 13 and 14.

- Southeast Bay of Bengal, Southwest Bay of Bengal and adjoining East Central Bay of Bengal during November 15 to 17.

The Tamil Nadu Fisheries Department had also instructed fishermen operating along the eastern coastal regions to return to shore by the night of November 12.

Fishing tokens will not be issued to fishing boats from November 13 until further notice.

Rain Expected in Tamil Nadu and Puducherry

The developing weather system is likely to influence rainfall activity across Tamil Nadu, Puducherry and Karaikal.

According to the weather forecast:

- Light rainfall is likely in parts of Tamil Nadu, Puducherry and Karaikal.

- Moderate to widespread rainfall is possible on November 15.

- Isolated heavy rainfall is forecast in parts of Tamil Nadu on November 15 and 16.

- The Andaman and Nicobar Islands may also receive heavy rainfall.

Rainfall activity will depend on the movement and strengthening of the low-pressure system over the Bay of Bengal.

Possible Cyclone Development Between November 1 19 and 25

The IMD`s extended-range forecast indicates the possibility of further intensification into a cyclonic storm during November 19–25.

However, the future movement, intensity and possible impact of the system remain subject to changes in weather conditions. Different weather models have also indicated variations in its potential track.

Further clarity is expected through upcoming IMD weather bulletins.

Coastal Residents and Fishermen Advised to Follow Weather Updates

With the low-pressure area expected to strengthen over the coming days, coastal communities and fishing personnel should closely follow official weather announcements.

Fishermen are advised to follow the restrictions issued by the IMD and the Tamil Nadu Fisheries Department and avoid entering the warned sea areas.

The coming days will be important for monitoring the system`s development and its possible impact on Tamil Nadu`s weather conditions.
