A well-marked low-pressure area over the Strait of Malacca and adjoining south Andaman Sea has positioned itself over Malaysia and the adjacent Strait of Malacca as of November 24, poised for rapid intensification into a depression over the South Andaman Sea within the next 24 hours, escalating further into the cyclonic storm Senyar—named after the Arabic word for "lion"—over the southeast Bay of Bengal in the following 48 hours.

The system is advancing west-northwestwards with increasing vigour, driven by an upper air cyclonic circulation over the Comorin area and adjoining Lakshadweep and the Indian equatorial ocean, where a separate low-pressure area is anticipated to develop around November 25, potentially amplifying regional weather disruptions across the southern peninsula.

While the India Meteorological Department has withheld precise landfall coordinates, the storm's trajectory suggests significant threats to coastal regions, with wind speeds in the Andaman and Nicobar Islands projected to reach 40-50 kmph over the next six days, accompanied by squally conditions that could endanger maritime navigation and low-lying settlements.

IMD has issued urgent advisories for intense rainfall and thunderstorms, forecasting heavy downpours over Tamil Nadu from November 25 to 27, Kerala and Mahe from November 24 to 26, Lakshadweep on November 24, and Andaman and Nicobar Islands on November 25 and 29, with very heavy episodes likely in Tamil Nadu on November 24 and from November 28 to 30, as well as in Andaman and Nicobar from November 26 to 28 and coastal Andhra Pradesh on November 30.

Thunderstorm activity with lightning is deemed very likely over Tamil Nadu until November 28, Kerala and Mahe through November 26, Lakshadweep on November 24, and coastal Andhra Pradesh and Yanam on November 27 and 28, prompting authorities in affected states to monitor developments closely and implement precautionary evacuations where necessary to mitigate potential flooding and infrastructure damage.
