Additional Information

·      What Are Cumulonimbus Clouds.?

Cumulonimbus clouds, often called “thunderclouds,” are towering giants that form during intense atmospheric conditions. Fuelled by excessive moisture and heat, these clouds can trigger heavy rain, hail and lightning. Their massive size—sometimes reaching 13 km—makes them a key driver of severe weather. When multiple clouds collide, the friction generates electric charges, resulting in frequent lightning strikes.

·      The Damini App

Launched in 2019, the Damini app (available on Google Play Store) is a lifesaver for thunderstorm-prone areas. With a lightweight file size of 2.63 GB, it uses minimal phone resources but requires active GPS and data connectivity. The app provides alerts 20-40 minutes before lightning strikes within a 20-40 km radius. According to the @IMD, it has reduced lightning-related deaths by providing timely warnings, especially in rural areas where 96% of India’s 2,000 annual lightning fatalities occur.

Impact Analysis

The thunderstorm alert has significant implications for South Bengal’s 80 million residents. Lightning strikes claim 2,000 lives annually in India with rural areas bearing the brunt (96% of fatalities). The @IMD’s red alert for five districts on June 2nd underscores the urgency, as frequent strikes could disrupt daily life, damage infrastructure and threaten agriculture. In Kolkata, power outages were reported in some areas due to last night’s storms (Source: X posts, June 3rd, 2025).

The Damini app’s role is critical. Its real-time alerts could save lives, especially in rural districts like South 24 Parganas and Purba Medinipur where awareness is low. Social media campaigns on X are amplifying safety messages with influencers urging followers to spread the word. Businesses including local shops and farmers’ markets, may face disruptions, as heavy rain could damage crops and halt outdoor activities.

The alert also highlights climate change’s role in intensifying weather patterns. Experts on X note that rising temperatures are fuelling stronger cumulonimbus clouds, leading to more frequent storms (100K+ mentions of #ClimateChangeImpact). This could push South Bengal into a cycle of extreme weather, demanding better preparedness.

Conclusion

South Bengal is bracing for a turbulent week as severe thunderstorms and lightning strikes loom from June 3rd to 9th, 2025. The @IMD’s warnings, powered by nowcast technology and the Damini app, aim to protect millions from nature’s wrath. With Kolkata already reeling from last night’s lightning barrage, residents must stay vigilant. By downloading the Damini app and following safety guidelines, South Bengal can weather this storm. Stay safe, stay informed and let’s ride out this chaos together.!
