West Bengal Weather: Low-Pressure System to Bring Heavy Rain Across South Bengal

West Bengal weather is set to remain unsettled as a fresh low-pressure area develops over the northwest Bay of Bengal, while an active monsoon trough continues to influence the southern parts of the state. The combination of these two weather systems is expected to bring heavy rainfall to several districts, with a yellow alert issued for parts of South Bengal.

The weather system is likely to intensify over the Bay of Bengal on Saturday, raising the possibility of widespread rain across Gangetic West Bengal. Coastal areas are also expected to experience stronger winds and rough sea conditions.

Fishermen along the West Bengal coast have been advised not to venture into the sea on Saturday due to the expected deterioration in weather conditions.

Low-Pressure Area Developing Over Bay of Bengal

According to the forecast, a low-pressure area is expected to form over the northwest Bay of Bengal on Saturday. The associated system is likely to extend across Gangetic West Bengal.

At the same time, the monsoon trough is extending through Kanthi towards the east-central Bay of Bengal. The interaction between these weather systems is expected to increase rainfall activity across South Bengal.

As a result, several districts could experience heavy showers, thunderstorms and gusty winds.

The latest West Bengal weather forecast suggests that the rainy spell may continue into the coming week, although rainfall intensity is expected to fluctuate from day to day.

Heavy Rain Forecast in Six South Bengal Districts

Heavy rainfall has been forecast for six districts of South Bengal on Saturday.

The districts likely to receive heavy rain are:

• Bankura
• Purulia
• Paschim Medinipur
• Jhargram
• Paschim Bardhaman
• Birbhum

A yellow warning has been issued for these areas, highlighting the possibility of intense rainfall over some locations.

Apart from these districts, Kolkata and other parts of South Bengal may also experience scattered rain accompanied by thunderstorms.

Gusty Winds Expected

Rainfall may not be the only weather concern.

According to the forecast, gusty winds with speeds of around 30–40 kmph could accompany thunderstorms and showers in several parts of South Bengal.

Residents in areas likely to experience thunderstorms have been advised to remain cautious, particularly during periods of strong winds and lightning.

Kolkata is also expected to see intermittent showers and thunderstorms, although rainfall intensity may vary across the city and neighbouring districts.

Rain May Ease Temporarily on Sunday and Monday

The West Bengal weather pattern is expected to change slightly after Saturday.

Rainfall activity across South Bengal may decrease on Sunday and Monday. However, the improvement is expected to be temporary.

Another spell of heavy rainfall is forecast from Tuesday through Thursday, with a yellow warning issued for several areas.

This means residents should remain prepared for another round of widespread rain even after the weather briefly improves at the beginning of the week.

Fishermen Warned as Sea Turns Rough

The developing weather system has also prompted warnings for the coastal areas of West Bengal.

As the low-pressure system forms over the Bay of Bengal, sea conditions are expected to become rough. Strong winds and high waves could make conditions dangerous for fishing activities.

Fishermen along the West Bengal coast have therefore been advised not to venture into the sea on Saturday.

The warning is particularly important for those operating smaller fishing boats, as rapidly changing weather conditions can create hazardous conditions offshore.

North Bengal Also Set for Rain

The unsettled West Bengal weather will not be restricted to the southern districts.

North Bengal is also expected to receive scattered rainfall across several districts. Thunderstorms accompanied by light to moderate rain are likely in parts of the region.

Darjeeling, Jalpaiguri, Malda, North Dinajpur and South Dinajpur may experience scattered thunderstorms and showers.

Heavy rainfall is also possible in Jalpaiguri, Alipurduar and North Dinajpur, where a yellow warning has been issued.

Rainfall Activity to Increase on Sunday

Rainfall activity in North Bengal is expected to increase on Sunday.

Malda and the two Dinajpur districts—North Dinajpur and South Dinajpur—could see more intense thunderstorms and rain.

Residents in these areas should remain alert to sudden changes in weather, particularly during thunderstorms.

However, the weather situation in North Bengal is expected to improve gradually from Monday, with rainfall activity likely to decrease.

Yellow Alert Amid Changing Weather Conditions

The repeated yellow alerts indicate that residents should remain cautious as weather conditions could change rapidly.

The combination of a low-pressure system and the active monsoon trough is expected to maintain rainfall activity over the state. While Sunday and Monday may bring some relief in South Bengal, another wet spell is expected from Tuesday onwards.

For coastal residents and fishermen, the sea-related warning remains particularly important as rough conditions are expected over the Bay of Bengal.

With the monsoon remaining active, the West Bengal weather forecast points to several days of rain, thunderstorms and gusty winds across both South and North Bengal.

Residents are advised to follow official weather updates and take necessary precautions during thunderstorms and periods of heavy rainfall.
