Heavy Rain Alert Across Eastern UP and Gorakhpur as Bay of Bengal System Intensifies

Even as the southwest monsoon commences its seasonal withdrawal from northwestern India, atmospheric dynamics over the Bay of Bengal are set to deliver a significant parting spell of heavy precipitation across eastern Uttar Pradesh. A well-marked low-pressure area formed over the Bay of Bengal is advancing along a north-northwest trajectory traversing Odisha and Bihar, bringing renewed moisture directly into the Purvanchal region. The India Meteorological Department (IMD) has sounded a heavy rainfall alert for multiple districts in eastern Uttar Pradesh, with intense shower activity commencing from September 24 and persisting over the next two to three days. While the formal cutoff date for the monsoon’s complete retreat from eastern Uttar Pradesh is recognized as October 6—and October 15 for the rest of peninsular India—this late-season weather revival is anticipated to trigger vigorous rain bursts across urban and rural belts.Severe Deficit in Gorakhpur: District Trails Normal Precipitation by 439.5 mmThe incoming wet spell brings critical hydrological respite to Gorakhpur, where cumulative seasonal precipitation has lagged well behind typical historical benchmarks. Meteorological records reveal that between June 1 and September 22, the district accumulated only 704.5 mm of rainfall against a long-period average normal of 1144 mm, translating to an acute deficit of 439.5 mm. Monthly precipitation breakdowns demonstrate sharp variations across the season: Gorakhpur registered 126.9 mm in June, peaked at 355.7 mm in July, and slumped sharply in August to just 108.2 mm against its August normal of 319.5 mm. Through September 22, the district logged 114.2 mm compared to the monthly standard expectation of 253.4 mm, turning August into the driest operational stretch of the current cycle.Weather System to Expand Inward: Lucknow, Kanpur, and Central Belts on WatchClarifying the synoptic behavior of the prevailing atmosphere, meteorologist T.B. Singh indicated that while the monsoon withdrawal line has commenced its departure through western borders in Rajasthan, low-pressure depressions from the maritime boundary often alter withdrawal trajectories. Forecasters project that this active system will extend inward past the eastern districts, delivering scattered to heavy showers across central Uttar Pradesh, including the urban agglomerations of Lucknow and Kanpur. The localized convergence will significantly elevate humidity levels, lower daytime temperatures, and temporarily revive agricultural replenishment before the southwest monsoon permanently recedes from the state.
