Kolkata Weather Takes Sudden Turn, IMD Issues Yellow Alert
West Bengal Weather Update | Heavy Rain & Thunderstorm Alert
Weather conditions across West Bengal have changed sharply, prompting the India Meteorological Department (IMD) to issue a Yellow Alert for several districts, including Kolkata.
According to the IMD, thunderstorms, lightning, strong winds, and moderate to heavy rainfall are likely to affect multiple parts of the state over the next 48 hours.
Officials said unstable atmospheric conditions and rising humidity levels are contributing to the sudden weather shift.
What Is the Current Situation?
The weather department warned that several districts could witness:
- Wind speeds between 40–60 km/h
- Heavy rainfall with thunderstorms
- Frequent lightning activity
- Sudden storm development in isolated areas
The IMD has advised residents to remain cautious, especially during evening and night hours when storm activity could intensify.
Districts Likely to Be Affected
The following districts are expected to face the strongest impact:
- Kolkata
- Howrah
- Hooghly
- North 24 Parganas
- South 24 Parganas
Authorities have also warned about possible:
- Waterlogging
- Traffic disruption
- Power cuts
- Falling trees and branches in vulnerable areas
Why Is the Weather Changing?
Meteorologists say the sudden change is linked to a local pressure system combined with increasing moisture levels over eastern India.
Such pre-monsoon weather activity is common during April and May in West Bengal, though officials believe this spell could be slightly more intense than usual.
IMD Advisory for Residents
The weather department has urged people to follow safety precautions during severe weather conditions.
Residents Are Advised To:
- Avoid unnecessary outdoor movement during storms
- Stay away from electric poles and trees
- Drive carefully during rainfall and low visibility
- Keep emergency lights and mobile phones charged
Advisory for Farmers
Farmers have also been advised to take precautionary measures ahead of expected rainfall.
Farmers Should:
- Store harvested crops safely
- Complete urgent harvesting work early
- Protect farming equipment from rain damage
How Long Will the Weather Remain Unstable?
According to the IMD, the unstable weather pattern is likely to continue for the next 48 hours before conditions gradually improve.
However, officials said localized thunderstorms may still occur in some areas depending on atmospheric changes.
Conclusion
West Bengal is expected to remain weather-sensitive over the next two days as thunderstorms and rainfall activity continue across several districts.
Residents are advised to stay updated with official IMD forecasts and take necessary precautions to remain safe during severe weather conditions.
