§  IMD Issues Heavy Rain Warning for West Bengal from September 28 (Panchami)

While the sun briefly appeared after Monday night’s devastating rainfall that claimed 11 lives through electrocution, Kolkata and surrounding districts face another round of heavy downpours from Thursday onwards. The India Meteorological Department has issued fresh warnings for widespread rain with thunderstorms across West Bengal, threatening to disrupt Durga Puja celebrations once again.

The weather department’s latest forecast reveals that heavy rainfall will persist until September 26 with Saturday (Panchami) particularly concerning for multiple districts. Regional Meteorological Center Director Habibur Rahman Biswas confirmed that East-West Midnapore, South 24 Parganas, Bankura and Jhargram could experience heavy to very heavy rainfall on Wednesday.

Renewed Weather Crisis Threatens Durga Puja Festivities

Despite the recent tragedy that left families devastated during Devi Paksha, crowds were spotted at pandals Tuesday evening, wading through waist-deep water with the simple logic— “Puja doesn’t come multiple times a year.!”. However, fresh weather warnings suggest more challenging days ahead for the festival celebrations.

Thursday and Friday will witness thunderstorms with lightning across all South Bengal districts. Saturday’s heavy rain warning specifically targets Bankura, East-West Midnapore, Howrah and South 24 Parganas, while Kolkata faces thunderstorms and moderate rainfall.

The IMD’s special bulletin for Durga Puja 2025 indicates that light to moderate rain will continue across South Bengal from September 24-29, with heavy rainfall warnings for coastal districts on multiple days. This prolonged wet spell could severely impact the festival atmosphere, forcing organizers to implement emergency measures.

District-wise Weather Breakdown and Warnings

·       Wednesday’s Forecast

o   Today, most areas in South Bengal face light to moderate rain with thunderstorms. Heavy rainfall (7-11 cm) is very likely at isolated places in Bankura, Jhargram, East Midnapore, West Midnapore and South 24 Parganas. Thunderstorms with gusty winds reaching 40-50 kmph are expected in coastal districts.

·       Thursday and Friday Outlook

o   Both days will see widespread light to moderate rain across South Bengal with thunderstorms. Coastal areas including South 24 Parganas, East Midnapore and West Midnapore face gusty winds of 40-50 kmph with lightning strikes. The weather pattern suggests continuous moisture influx from the Bay of Bengal systems.

·       Saturday (Panchami) - Peak Concern

o   Heavy rain warnings are in effect for Bankura, East-West Midnapore, Howrah and South 24 Parganas on September 28. Kolkata will experience thunderstorms with lightning, though rainfall intensity may remain moderate. Wind speeds could reach 40-50 kmph in coastal districts, making outdoor activities risky.

Historical Weather Context and Comparisons

o   Weather records show that September has historically been challenging for Kolkata during festival season. Approximately 47 years ago in September 1978, Kolkata recorded 370mm rainfall in 24 hours, creating widespread flooding. The 1986 deluge brought 270mm in a day on September 26, while 2007 witnessed 174.4mm on September 25.

Monday night’s rainfall measured 251.4mm, ranking among the city’s most intense September downpours in recent decades. Climate data indicates that Kolkata typically experiences 15-22 rainy days in September with average rainfall around 271mm for the entire month.

The current weather pattern mirrors the devastating 2020 pre-Puja period when similar Bay of Bengal systems brought continuous rainfall, affecting pandal preparations and public celebrations. Meteorologists note that such extreme weather events are becoming more frequent due to climate change impacts on regional monsoon patterns.

Bay of Bengal Systems Driving Weather Chaos

The persistent rainfall is attributed to multiple low-pressure areas forming over the Bay of Bengal. The first system, currently positioned over northeast Bay of Bengal is moving northwestward and will influence weather until Wednesday. A second low-pressure area is expected to develop around September 25, potentially intensifying into a depression by September 26-27.

Dr. H.R. Biswas from the Regional Meteorological Center explained, “Three consecutive weather systems are likely to affect Bengal over the next two weeks. If the second system crosses north Odisha, South Bengal including Kolkata will experience heavy rainfall during the festival period”. The third system, emerging from the South China Sea, could bring additional rain around September 30.

These weather patterns are typical during monsoon transition periods when systems over the Bay of Bengal carry significant moisture into Gangetic Bengal. The IMD has advised residents to carry umbrellas and plan pandal visits accordingly, as multiple rain spells are expected during peak celebration days.

Public Safety Measures and Advisory

Authorities have issued comprehensive safety guidelines following Monday’s tragic incidents. The warning includes risks of severe waterlogging in low-lying areas, traffic congestion during intense rainfall and potential lightning strikes. Citizens are advised to avoid open areas during thunderstorms and maintain distance from electrical installations.

Fishermen have been strictly prohibited from venturing into the sea along West Bengal coasts until September 27 due to rough conditions with wind speeds reaching 40-50 kmph. The IMD has also cautioned about reduced visibility during heavy rain spells, urging commuters to exercise extreme caution.

Emergency response teams are on high alert with drainage systems being monitored continuously. The Kolkata Municipal Corporation has opened all lock gates toward the Hooghly River to facilitate water drainage. Educational institutions may declare holidays if weather conditions deteriorate further.

Economic and Cultural Impact Assessment

The continuous rainfall threatens to severely impact Durga Puja’s economic ecosystem. Traders are already reporting decreased footfall during the crucial pre-Puja shopping period with concerns mounting about revenue losses if weather conditions persist. Pandal organizers are implementing emergency measures including waterproofing, drainage pumps and structural reinforcements.

Tourism revenue, a significant component of Bengal’s economy during Durga Puja, faces substantial risk. The festival typically attracts millions of visitors from across India and abroad but prolonged rainfall could deter tourists and reduce local business opportunities. Cultural events, processions and outdoor celebrations may require rescheduling or indoor alternatives.

Local vendors, particularly those selling festival merchandise, food and decorative items are experiencing reduced sales. The timing is particularly challenging as Durga Puja preparations require significant investment in perishable goods and temporary installations.

Conclusion

As West Bengal braces for another challenging weather phase, the resilience of Durga Puja celebrations will be tested once again. While Saturday’s heavy rain warning for multiple districts raises serious concerns, the indomitable spirit of Bengali culture continues to shine through adversity.

The weather department’s extended forecast suggests that light to moderate rain will persist through October 2, covering the entire Durga Puja period. However, proper preparation, safety measures and community solidarity can help minimize the impact on this cherished festival.

Citizens must remain vigilant, follow weather updates regularly and prioritize safety over festivities. The tragic loss of 11 lives serves as a stark reminder that no celebration is worth risking human life.
