India Meteorological Department says the Bay of Bengal weather system will intensify quickly. A well-marked low is expected to become a depression today, 15 November. It may strengthen into a cyclonic storm by Monday evening, 16 November. Students across Tamil Nadu, Puducherry, and Andhra should prepare for rain-led travel and exam changes.
Model guidance keeps cyclogenesis over the central South Bay, then a north-northwest drift. Officials have not specified landfall or naming, pending intensification. IMD has urged, “Fishermen out at sea are advised to return to coasts by 15th November, 2026.” Expect frequent bulletins as the system consolidates today.
IMD Bay of Bengal depression: What the next 48 hours mean
Expect a staged escalation over open waters through Monday. IMD indicates depression formation today over the southeast Bay, then cyclonic storm strength over the central Bay by Monday evening. Rain bands could brush coastal Tamil Nadu and south Andhra late tonight into Monday, with stronger squalls near the coast.
| Date | Stage | Zone | Key advisory |
|---|---|---|---|
| 15 Nov | Depression likely | Southeast Bay | Plan essential travel only; monitor district alerts. |
| 16 Nov | Cyclonic storm likely | Central Bay | Expect stronger winds, squally rain near coast. |
| 15–18 Nov | Rough to very rough sea | Southwest Bay | No fishing; port operations may slow. |
South India rain and travel advisory: flights, trains, roads
Build buffer time for airport and railway reporting, and keep tickets handy. Waterlogging risk rises during squalls, especially near coastal corridors and low-lying city pockets. Keep devices charged and store offline tickets. IMD flags rough to very rough seas over the Southwest Bay during 15–18 November.
Exam schedule watch: schools, colleges, and entrance tests
Sunday exams may face delays if heavy bands arrive by evening. For Monday, 16 November, institutions in coastal districts could review timings based on rain and power status. Track notices from district administrations, universities, and exam controllers. Carry waterproof sleeves for admit cards and reach early if conditions permit.
Fishermen and coastal safety: official IMD advisory and helplines
Fishermen should not venture into the sea from today. Those already at sea must return by tonight, 15 November, per IMD guidance. Port authorities may issue additional signals. For forecast clarification, IMD lists 011-2434-4599 on bulletins; follow local disaster control rooms for district-specific alerts.
How to track IMD updates and district warnings in real time
Follow IMD’s cyclone and sea-area bulletins for system stage and track. Cross-check with your district collector’s advisories before starting travel. Students should finalise Monday logistics tonight, keep rain-safe kits ready, and refresh notifications by early morning, 16 November. Expect updated guidance through Monday evening as intensity and track clarify.
