With the arrival of October—historically a volatile month for tropical storms along India’s eastern seaboard—fresh signals indicate potential cyclonic activity brewing in the Bay of Bengal during the second week of the month.
Coastal residents and disaster authorities are maintaining close watch following weather forecasts hinting at a developing system between October 8 and 15.
According to prominent meteorologist Dr. Surendranath Pashupalak, the Bay of Bengal is currently transitioning from the active southwest monsoon phase to the post-monsoon period. While the monsoon flow has weakened over the north-western and west-central parts of the bay, it remains active over the east-central and southern Bay of Bengal, as well as the Andaman Sea. This atmospheric shift is restructuring lower-level wind patterns, creating an environment conducive to tropical cyclogenesis.
Short-Term Forecast: “October Heat” to Persist Until Oct 7
Before any potential storm system takes shape, Odisha is expected to experience typical early-October weather conditions. Until October 7, the state will witness predominantly dry weather accompanied by bright sunshine, elevated daytime temperatures, and high humidity—a combination commonly known as “October heat.” Isolated afternoon thunderstorms and lightning remain possible in select interior and coastal pockets.
The Oct 8–15 Window: High Potential for System Formation
Global weather forecasting models indicate that a low-pressure system or cyclonic circulation is likely to form in the Andaman Sea, south-east Bay, or east-central Bay of Bengal between October 8 and 15.
Dr. Pashupalak emphasized that while atmospheric indicators point strongly toward system formation, predicting the exact dates, intensity, and landfall point at this early stage involves significant uncertainty.
Possible Trajectories
The path of the potential storm will largely depend on the exact latitude where the atmospheric system consolidates:
- Southern Origin: If the system develops further south near the Andaman Sea, it is more likely to track west-northwestward toward Tamil Nadu or southern Andhra Pradesh.
- Central Origin: If consolidation occurs further north in the east-central Bay of Bengal, the system could move toward northern Andhra Pradesh or the Odisha coastline.
- Recurvature Risk: Should the steering ridge weaken, the system could recurve north or north-eastward toward Bangladesh or Myanmar.
Clarity Expected by October 5
Meteorologists caution that it is too early to determine whether the developing system will intensify into a severe cyclonic storm or make direct landfall in Odisha.
A clearer picture regarding the trajectory, wind speeds, and potential impact zones will emerge following the fresh weather model runs around October 5.
Authorities continue to advise coastal populations to remain updated through official bulletins.
