Details & Context
The southwest monsoon is making a bold entry into West Bengal, arriving earlier than expected. On May 13th, 2025 monsoon winds swept into the Nicobar Islands, South Bay of Bengal and Andaman Sea as reported by the India Meteorological Department (@IMD). Now, these winds have reached the eastern Bay of Bengal, covering the Andaman Islands and advancing toward central and northern Bay regions. A dynamic cyclonic circulation in the southeast Bay, tilting southwest is fuelling this stormy weather.

Quotes
· “The monsoon’s early arrival is a game-changer. Expect heavy rain and storms across West Bengal for the next few days.” – An @IMD official, quoted in a recent weather bulletin.
· “Kolkata’s streets are already waterlogged. This rain is intense.!” – A local resident’s post on X, reflecting real-time sentiment.
· “Farmers are worried but the cooler weather is a relief.” – A farmer from Purulia, shared via a local news outlet.
Additional Information
The early monsoon surge is linked to a strong cyclonic circulation in the Bay of Bengal, as noted in X posts and @IMD updates. This system is driving moisture-laden winds causing widespread rain and thunderstorms. In South Bengal, districts like Purulia and Bankura are at higher risk of Kalbaishakhi known for sudden destructive winds. North Bengal’s hilly regions, especially Darjeeling and Kalimpong, face potential landslides due to heavy rain, a concern echoed in X discussions.
The @IMD’s forecast aligns with recent web reports, predicting a 2-3°C temperature drop by Wednesday, offering relief from the pre-monsoon heat. However, the high humidity (100% in Kolkata) is making conditions sticky with waterlogging already reported in low-lying areas. X users have shared images of flooded Kolkata streets, urging civic authorities to act. The weather system’s intensity is expected to peak Monday-Tuesday, with North Bengal’s upper districts bearing the brunt.

Impact Analysis
This stormy weather is a double-edged sword for West Bengal. On one hand, the rain and cooler temperatures (down from 36.2°C to ~34°C) provide relief from the scorching heat, benefiting residents and crops in drought-prone areas like Purulia. On the other hand, heavy rain and Kalbaishakhi pose serious risks. Waterlogging in Kolkata could disrupt traffic and daily commutes while hailstorms in South Bengal may damage crops and property. In North Bengal, heavy rain raises fears of flash floods and landslides, especially in Darjeeling and Alipurduar.
X posts highlight public concern with hashtags like #KolkataRain and #WestBengalWeather trending as users share real-time updates. The fishing and agriculture sectors are on high alert with coastal communities advised to avoid sea travel due to gusty winds. Schools and offices may face closures if flooding worsens, and power outages from lightning strikes are a growing worry. The @IMD has issued advisories for farmers to protect crops and for residents to avoid open fields during storms.
Conclusion
West Bengal’s weather is turning wild with heavy rain, thunderstorms and gusty winds sweeping across 12 districts. From Kolkata’s waterlogged streets to Darjeeling’s rain-soaked hills, the early monsoon is making its mark. While the cooler weather brings relief, the risks of flooding, hailstorms and landslides demand caution. As the state navigates this turbulent week, staying informed and prepared is key. Keep an eye on the skies and stay safe, Bengal.!
