IMD Weather Update, October 23, 2026: A developing weather system over the Bay of Bengal has raised concerns about heavy rainfall, thunderstorms and strong winds across several parts of India. According to the India Meteorological Department (IMD) bulletin quoted in the latest reports, a low-pressure area formed over the east-central and adjoining southeast Bay of Bengal on October 23.
The system is forecast to strengthen into a depression on October 24, followed by a deep depression on October 25. It could intensify further into a cyclonic storm over the west-central Bay of Bengal by the morning of October 26.
The developing system is expected to move west-northwestwards towards the north Andhra Pradesh and adjoining south Odisha coasts over the following two days.
Meanwhile, separate weather disturbances affecting southern India could bring heavy to very heavy rainfall to parts of Tamil Nadu, Kerala, Karnataka, Puducherry and Lakshadweep.
Importantly, the system had not yet become a cyclonic storm as of the October 23 bulletin. Its eventual intensity, movement and coastal impact will depend on further development.

These are forecast stages, not confirmation that the system has already reached cyclone intensity.
IMD Confirms Low-Pressure System Over Bay of Bengal
The IMD's October 23 coastal weather bulletin confirms that the low-pressure area remained over the east-central and adjoining southeast Bay of Bengal during the day.
An associated cyclonic circulation extended up to approximately 5.8 kilometres above mean sea level.
The department forecast that the system would strengthen over the following three days before approaching the eastern coastline.
According to the IMD, the north Andhra Pradesh and adjoining south Odisha coasts could experience the system's effects around October 28, although its precise track and intensity remain subject to change.
Which States May Receive Heavy Rainfall?
Several states and Union Territories are expected to experience significant rainfall during the coming days.
| State or Region | Reported Rainfall Outlook |
|---|---|
| Tamil Nadu | Heavy to very heavy rainfall in isolated areas through October 26 |
| Puducherry and Karaikal | Heavy rainfall risk through October 26 |
| Kerala | Heavy rainfall in some areas through October 25 |
| Lakshadweep | Heavy rainfall risk through October 24 |
| Coastal Karnataka | Rain and thunderstorms in some locations |
| Andaman and Nicobar Islands | Heavy rainfall in isolated areas through October 26 |
| Coastal Andhra Pradesh | Risk of extremely heavy rainfall on October 27–28 |
| Odisha | Heavy rainfall risk on October 27–28 |
These warnings do not mean that every district within the listed states will experience severe weather.
The IMD's subdivision-wise warning issued on October 23 specifically identifies extremely heavy rainfall risk for coastal Andhra Pradesh on October 27 and 28, followed by a heavy-rain warning on October 29.
Andhra Pradesh and Odisha on Alert for October 27–28
The eastern coastline is receiving particular attention because of the projected west-northwestward movement of the developing weather system.
According to the forecast, the system may approach the north Andhra Pradesh and adjoining south Odisha coasts around October 28.
The Andhra Pradesh State Disaster Management Authority has also warned about the potential intensification of the low-pressure system and advised fishermen to return to the coast.
Heavy rainfall during a developing cyclonic system can create risks of local flooding, waterlogging, damage to temporary structures and disruption to transportation.
However, the location and timing of any eventual landfall should not be treated as confirmed until the IMD issues a more specific forecast.
Why Is Southern India Also Receiving Heavy Rain?
The heavy rainfall expected over parts of Tamil Nadu, Kerala and nearby areas is influenced by weather activity around the Comorin region and adjoining southern coastal areas.
This is distinct from the developing low-pressure system farther east over the Bay of Bengal.
The presence of multiple weather disturbances can lead to widespread rain across different regions during the same period.
Residents should therefore follow district-specific warnings rather than assuming that all rainfall is directly caused by the potential cyclone.
What Precautions Should Fishermen and Coastal Residents Take?
People living in coastal districts should monitor official weather warnings, particularly as the system develops between October 24 and 28.
Fishermen should follow the latest sea-area advisories and avoid entering waters for which warnings have been issued.
Coastal residents should secure loose outdoor objects, keep essential medicines and communication devices accessible, and avoid unnecessary travel during severe weather.
During thunderstorms, people should move indoors and avoid open fields, isolated trees and exposed coastal locations.
Drivers should exercise additional caution on waterlogged roads, while residents in flood-prone areas should follow instructions from local disaster-management authorities.
Where Can You Check Official Cyclone Updates?
The India Meteorological Department regularly publishes cyclone forecasts, rainfall warnings and coastal bulletins.

- IMD official weather website
- Regional Specialised Meteorological Centre, New Delhi
- NDMA SACHET disaster alert portal
Weather warnings may change as the system moves and intensifies.
Final Takeaway
The Bay of Bengal low-pressure system is forecast to become a depression on October 24, a deep depression on October 25 and potentially a cyclonic storm by October 26.
The developing system could approach the north Andhra Pradesh and south Odisha coasts around October 28, while parts of southern India are already facing separate heavy rainfall risks.
Residents should treat the cyclone as a developing forecast, not an already confirmed landfall event, and follow updated IMD advisories for their districts.
