Cyclone Season Begins : Why October Remains a Sensitive Month for Odisha

October is once again sounding the alarm over the Bay of Bengal. Just when the monsoon season is drawing to a close, the possibility of a fresh weather system emerging over the Andaman Sea has put coastal areas on watch. A potential cyclonic circulation around October 12 could lead to a low-pressure area around October 13, with the system possibly becoming a depression over the southern and adjoining central Bay of Bengal around October 15.

But before panic spreads, there is an important point to remember this is only a forecast possibility at this stage, not a confirmed cyclone or landfall warning. Still, with October historically known for powerful cyclones affecting the Odisha coast, every developing system over the Bay of Bengal is being watched closely.

A fresh weather system is being closely watched over the Bay of Bengal, but there is no confirmed cyclone or landfall threat at this stage. According to the forecast scenario cited in the supplied report, a new cyclonic circulation could emerge over the North Andaman Sea around October 12, potentially leading to the formation of a low-pressure area around October 13. If the system strengthens further, it could develop into a depression over the southern and adjoining central Bay of Bengal around October 15.

However, these are extended-range projections and can change considerably as the system develops. As of October 2, the India Meteorological Department’s latest sea-area bulletin reported no storm warning over the Bay of Bengal, with the sea remaining generally smooth to slight in the areas covered by the bulletin.

The possibility of a new system is nevertheless attracting attention because October is climatologically an important month for post-monsoon cyclonic activity over the Bay of Bengal. The region becomes particularly favourable for tropical systems during the post-monsoon transition, when atmospheric circulation and oceanic conditions can support the formation and intensification of low-pressure systems. Historical records underline why Odisha’s coastline remains watchful during this period. The 1999 Odisha Super Cyclone developed from a depression over the North Andaman Sea before becoming an extremely severe system and crossing the Odisha coast; the India Meteorological Department notes that several severe cyclonic storms have historically developed over the east-central Bay of Bengal and crossed the

Odisha coast during October. October has also witnessed major cyclones such as Phailin in 2013, which made landfall near Gopalpur on October 12, and Titli in 2018; IMD records also document the severe impacts associated with these systems. This history explains why every emerging weather system during October receives close attention along the Odisha and Andhra Pradesh coasts. However, the appearance of a low-pressure area does not automatically mean that a cyclone will form or that it will hit Odisha.

A developing system must be monitored for its organisation, central pressure, wind speed, movement and interaction with surrounding atmospheric conditions before its intensity and track can be assessed with greater confidence. For now, residents along the Odisha coast need not panic, but fishermen, coastal communities and disaster-management authorities will continue to watch official IMD updates closely. The coming days will be important in determining whether the projected mid-October system actually develops and, if it does, how strong and where it eventually moves.
