There is a low-pressure area over the Southwest Bay of Bengal and adjoining Sri Lanka and the Comorin region. This system will move west-northwest towards the Southeast Arabian Sea and the Lakshadweep region. It may pick up strength over the open waters of the south-central Arabian Sea. In the meantime, another low-pressure area is likely to form over the Southeast Bay of Bengal and adjoining central equatorial parts anytime around 21st/22nd Nov 2025.
Once the low-pressure area forms, there is a fair chance of strengthening and tracking west-northwest towards the south-central parts of the Bay of Bengal and further on to the Southwest Bay of Bengal. Since model accuracy drops with a lead time of 4–5 days, developments will be closely monitored. In anticipation, coastal parts of Tamil Nadu and Andhra Pradesh will be at risk of inclement weather conditions early next week.
Climatology and the season both favour intensification of such systems over the Bay of Bengal around this time of the year. Earlier, the Bay of Bengal had hosted Severe Cyclonic Storm Montha in the last week of October 2025. Cyclones forming in November often threaten the coastlines of Tamil Nadu, Andhra Pradesh, Odisha, and West Bengal. The majority of these systems head towards Andhra Pradesh and Odisha. Some of these storms recurve, keeping close to the East Coast and travelling up towards West Bengal and Bangladesh. Information regarding this weather system will be updated and shared after the low-pressure area forms over the Bay of Bengal.
