New low-pressure area developing over Bay of Bengal: Met
The Statesman | 26 September 2025According to the Meteorological Department, thunderstorms with lightning will continue in south Bengal districts, including Kolkata, till Sunday, when Durga Puja will begin as per tradition. However, the weather office has ruled out any possibility of heavy rain till Saturday.
“There is a cyclonic circulation over the Bay of Bengal adjacent to the Myanmar coast. It is slowly moving westward. Due to this, a new low-pressure area will be formed in the north Bay of Bengal today. This will gradually transform into a depression on Friday. By Saturday, the low pressure may enter the land through the south Odisha coast. Due to this, there is a possibility of scattered light to moderate rain in the south Bengal districts, including Kolkata, on Saturday,” said a Meteorological Department official.
Apart from this, there is a possibility of another cyclonic circulation forming in the Bay of Bengal on ‘Ashtami’.
As a result, the intensity of thunderstorms may start again from 1 September. However, it is still premature to predict the exact course of that weather system.
Meanwhile, rain is likely in Kolkata, Howrah, Hooghly, North 24-Parganas, South 24-Parganas, East Midnapore, West Midnapore, Jhargram and Bankura districts from Friday. There is a possibility of heavy rain in South 24-Parganas, East Midnapore, West Midnapore and Jhargram districts on Saturday.
Apart from this, thunderstorms will continue in all the southern districts till Sunday. Along with this, there will be gusty winds at a speed of 30 to 40 kilometres per hour.
Meanwhile, there is little possibility of rain in north Bengal for now. There is a possibility of light rain with thundershowers and lightning at one or two places, but there is no possibility of heavy rain. There is a possibility of rain in Darjeeling, Jalpaiguri and North Dinajpur districts on Thursday.
There is also a rain alert in Cooch Behar on Friday. There may be rain in all districts of north Bengal on Saturday.
