Sources: 2. Developments: 2. A cyclonic storm developing in the Bay of Bengal initially triggered forecasts for unseasonal rain, thunderstorms, and strong winds across approximately 20 Indian states, including Uttar Pradesh, Delhi, Bihar, and Jharkhand. In late October, meteorological models predicted the system would intensify toward the coasts of northern Andhra Pradesh and southern Odisha, bringing potential risks to standing crops in eastern Uttar Pradesh. By early November, the system, identified as Cyclone Murasu, made landfall on the Andhra Pradesh coast. While West Bengal was not expected to face a direct hit, the cyclone and associated low-pressure systems delayed the onset of winter in the region. Temperatures in Kolkata remained above normal, with the Alipore Meteorological Department suggesting that consistent winter weather might not arrive until early December, despite expected temperature dips following the clearing of cloud cover. ## Timeline ### 2026-11-02: Cyclone Murasu delays winter onset in West Bengal Cyclone Murasu and a Bay of Bengal low-pressure system are delaying the arrival of winter in West Bengal, with significant temperature drops expected later in November or December. 2 sources. https://clstr.news/cluster/cyclone-murasu-delays-winter-onset-in-west-bengal ### 2026-10-24: Cyclone in Bay of Bengal to trigger unseasonal rain across North India A cyclonic storm in the Bay of Bengal is set to bring unseasonal rain, thunderstorms, and wind to several Indian states, including Uttar Pradesh, Bihar, and Delhi, starting late October. 5 sources. https://clstr.news/cluster/cyclone-in-bay-of-bengal-to-trigger-unseasonal-rain-across-north-india --- Cite as: Bay of Bengal cyclonic activity and weather impacts.
