Weather patterns in eastern India have shown variability leading up to the Durga Puja festival. Initially, the India Meteorological Department (IMD) predicted drier conditions for West Bengal, including Kolkata, as a depression moved away from the north Andaman Sea and the southwest monsoon began to withdraw.

However, subsequent forecasts for Odisha indicated potential disruptions to festivities. A developing cyclonic circulation in the Bay of Bengal was expected to emerge around October 12, with the possibility of intensifying into a depression by October 15. If this system moves toward the Andhra Pradesh-Odisha coast, it could bring widespread rain during the festive period starting October 16.
