The India Meteorological Department (IMD) has forecast a significant change in weather conditions across West Bengal later this week, with thunderstorms, strong winds and possible hailstorms expected to affect several districts of South Bengal, including Kolkata, from Friday. While the state is currently experiencing mild spring weather, meteorologists have indicated that a fresh spell of unstable conditions is likely to develop towards the weekend.
According to the IMD, dry weather is expected to continue across both South and North Bengal on Wednesday and Thursday, with no major rainfall activity anticipated during this period. However, conditions are set to shift from Friday onwards with the onset of Nor’wester activity, locally known as Kalbaisakhi, which typically brings sudden thunderstorms, lightning and gusty winds during the pre-monsoon season in eastern India.
In Kolkata, the day began with a partly cloudy sky and light haze, although brief sunny intervals were observed. Weather officials said the sky is likely to clear gradually during the day. The minimum temperature in the city was recorded at 24.6 degrees Celsius, slightly above normal, while the maximum temperature is expected to hover around 31.9 degrees Celsius, which is below the seasonal average. Despite relatively moderate daytime temperatures, both day and night temperatures are showing a gradual upward trend, indicating the transition towards warmer conditions.
From Friday onwards, Kolkata and adjoining areas are likely to witness cloudy skies accompanied by thunderstorms and rainfall. Strong winds associated with Nor’wester systems are also expected, which could lead to localized disruptions. The Alipore Meteorological Office has warned that thunderstorms and rain are likely across all districts of South Bengal on Friday and Saturday, with districts such as Purulia, Bankura, Jhargram, Paschim Medinipur and Purba Bardhaman likely to experience gusty winds ranging between 50 and 60 kilometres per hour. Isolated hailstorms are also expected in some areas.
Weather conditions in South Bengal are expected to remain humid due to high moisture levels in the atmosphere, particularly in coastal regions. Morning haze may continue during the week, while temperatures are likely to rise gradually, adding to the discomfort before the onset of storm activity.
In North Bengal, adverse weather conditions are expected to affect several districts on Wednesday, with forecasts of thunderstorms, heavy rainfall and possible hail. However, this activity is likely to reduce after the afternoon, followed by relatively stable conditions on Thursday. Rainfall intensity across the state is expected to remain low briefly before increasing again from Friday.
The IMD continues to monitor the evolving weather pattern and has advised residents to remain alert and follow official updates. The forecast is particularly important for those planning travel or outdoor activities, as Nor’wester storms can develop rapidly and bring sudden changes in weather, including strong winds and lightning, posing potential risks to safety and property.
