The India Meteorological Department (IMD) on Saturday, 5 September confirmed that rainfall intensity has eased across south Bengal, with no heavy rain warning issued for the region — including Kolkata — over the next few days. Meanwhile, several north Bengal districts are forecast to receive moderate to heavy rainfall through Monday, as a low-pressure system continues to influence weather across the state.

Weather System Behind the Pattern

According to the Met Office, a low-pressure system remains active over the region, with the southwest monsoon trough stretching from Rajasthan to Manipur through north Bengal. This configuration is driving the divergence in rainfall distribution between the state's northern and southern zones. Light to moderate rain accompanied by thunderstorms is expected across parts of south Bengal in the coming days, though no heavy-rain alerts have been raised.

North Bengal Districts on Alert

Rain activity is expected to be significantly more pronounced across north Bengal. The IMD has forecast heavy rainfall in Malda, South Dinajpur, and Jalpaiguri districts within the next 24 hours. Murshidabad — which straddles the boundary between north and south Bengal — is also likely to receive heavy rain in the same window. Thunderstorms and intermittent showers are expected to persist across other north Bengal districts through Monday.

Kolkata Gets a Breather

Kolkata experienced continuous rainfall over the three days preceding Friday, 5 September, leading to waterlogging across several city stretches. Friday brought a marked respite as rainfall remained largely absent, allowing inundated areas to drain. The Met Office has confirmed no possibility of heavy rain in the city over the next three to four days, though isolated spells of light to moderate rain may still occur. No warning has been issued for fishermen along the south Bengal coast for the next 24 hours.

Kolkata Temperature and Humidity

On Friday, Kolkata recorded a maximum temperature of 31.08 degrees Celsius — marginally below normal — while the minimum settled at 25.09 degrees Celsius. Relative humidity ranged between 67% and 98%. On Saturday, the sky is expected to remain largely cloudy, with temperatures hovering around 32 degrees Celsius and 27 degrees Celsius.

With the monsoon trough remaining active, weather conditions across Bengal are likely to remain unsettled through the early part of next week, though the heaviest burden will continue to fall on the northern districts.
