# Low-pressure system threatens rain during Bengal Puja week 2026-09-21T09:46:57+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet Kolkata and several West Bengal districts face rain and gusty winds from Tuesday, 22 September, as a low-pressure system over the Bay of Bengal strengthens. The India Meteorological Department has warned of thunderstorms, lightning and winds of 40 to 50 kmph in coastal areas like East Midnapore and South 24 Parganas. Heavy rain is likely in Sub-Himalayan West Bengal from 23 September, with very heavy showers indicated for 25 September. The unsettled spell coincides with final Durga Puja preparations, raising concerns over pandal work, outdoor shopping and travel. The IMD forecast shows rain or thundershowers continuing in Kolkata at least through 25 September, with gusty winds accompanying thunderstorms. The system is expected to influence weather across the state over the coming days as the countdown to the festival continues. ## Indian Opinion Analysis This low-pressure system is the same monsoon trough feature that often delivers a burst of rain to the east coast in late September. Durga Puja falls between the autumn equinox and the winter monsoon onset, making last-minute weather disruption a recurring concern for organisers. Pandal construction is typically in its finishing stage now, tarpaulin and bamboo structures are vulnerable to gusts above 40 kmph. Waterlogging in low-lying Kolkata neighbourhoods like Tollygunge and Behala can stall foot traffic during the peak shopping days. The IMD watches for the system to move inland over Bangladesh or recurve into the northeast, a track toward Odisha would spare Kolkata the heaviest spells. Pandal committees will watch the 22 September morning bulletin before deciding whether to anchor extras or delay finishing work. ## Coverage - english.mathrubhumi.com Tags: Bay of Bengal, Durga Puja, India Meteorological Department, Kolkata, West Bengal Canonical: https://indianopinion.org/low-pressure-system-threatens-rain-during-bengal-puja-week/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
