The India Meteorological Department (IMD) on Friday issued an alert predicting the formation of a fresh low-pressure area over the Bay of Bengal on September 25, 2025, which could bring widespread rainfall to several districts of Odisha.
According to IMD’s forecast, a cyclonic circulation is expected to form over the east-central and adjoining northeast Bay of Bengal around September 24, before intensifying into a low-pressure system the following day. The system is likely to move towards the Bangladesh–Myanmar coast, with its impact being felt across eastern India.
Weather Pattern and Intensification
IMD officials indicated that the system may further strengthen into a depression around September 26. The development is expected to increase rainfall activity across coastal and interior Odisha, particularly between September 24 and 26.
“Under the influence of this system, several districts of Odisha will receive moderate to heavy showers. Rainfall intensity in northern Odisha is expected to increase between September 27 and 28,” the forecast stated.
Expert Analysis
Weather expert highlighted that the situation could evolve further due to the interaction of two different weather systems.
“A cyclonic circulation is likely to form over the northwest Bay of Bengal between September 23 and 24, which may intensify into a low-pressure system near the Odisha coast around September 25–26. Meanwhile, another system is developing over the South China Sea, which is expected to turn into a severe cyclonic storm by September 22. While it will weaken after landfall in Bangladesh or Myanmar, its remnants may merge with the Bay of Bengal low-pressure system, thereby enhancing rainfall activity,” Sahoo explained.
He added that rainfall intensity is expected to peak over north Odisha districts from September 26 onwards, raising the possibility of flood-like situations in low-lying areas.
Impact on Odisha
-
September 24–26: Moderate to heavy rainfall likely in several coastal and central districts.
-
September 27–28: Increased rainfall activity in north Odisha, including Mayurbhanj, Balasore, and Keonjhar.
-
Possibility of waterlogging, localized flooding, and disruption of transport in some areas.
Authorities have been advised to stay prepared for contingency measures, especially in flood-prone districts. Farmers are also being alerted about possible crop damage in case of heavy and prolonged showers.
Monitoring and Preparedness
The Special Relief Commissioner’s office in Odisha has already begun coordinating with district administrations for precautionary measures. The IMD has advised fishermen to stay cautious and avoid venturing into the Bay of Bengal during the period of intensified weather activity.
Given the expected interaction of multiple weather systems, meteorologists have cautioned that rainfall distribution may vary depending on the eventual track and strength of the low-pressure area. Continuous monitoring will be essential in the coming days.
Conclusion
With the Bay of Bengal entering its peak cyclone season, the possibility of multiple weather systems interacting raises concerns of intense rainfall and localized flooding across Odisha. While the IMD has assured timely updates, residents and local authorities have been urged to remain vigilant and take necessary precautions.
