IMD has advised people to stay indoors during thunderstorms and avoid open areas, trees or water bodies, as lightning strikes are possible.

The India Meteorological Department (IMD) has said that West Bengal would continue to experience rain and thunderstorms over the next few days. Several districts are under yellow alerts, while a few northern districts are facing orange alerts for heavy rain.

In South Bengal, the forecast shows light to moderate rain or thundershowers at many places. Districts including Kolkata, Howrah, Hooghly, North 24 Parganas, South 24 Parganas, East Midnapore, West Midnapore, Jhargram, Purulia, Bankura, East Bardhaman, West Bardhaman, Birbhum, Murshidabad and Nadia are under yellow alert on different days this week.

The warning is for thunderstorms with lightning and gusty winds of 30–40 kmph at one or two places. These alerts are valid especially between September 13 and 16. IMD has advised people to stay indoors during thunderstorms and avoid open areas, trees or water bodies, as lightning strikes are possible.

In North Bengal, the alerts are stronger. The districts of Darjeeling, Alipurduar and Jalpaiguri are under orange alert for heavy to very heavy rainfall (7–20 cm) on September 13 and 14. Alongside, yellow alerts for heavy rainfall (7–11 cm) have been issued for Kalimpong, Cooch Behar and North Dinajpur, while South Dinajpur and Malda are under yellow warnings for thunderstorms with lightning and gusty winds. These conditions are expected to continue for the next few days, bringing widespread rain to most parts of North Bengal. The IMD has also cautioned that landslides are possible in the hills of Darjeeling and Kalimpong, while waterlogging may occur in low-lying areas of Jalpaiguri, Alipurduar and Cooch Behar.

For Kolkata, the local forecast for the next 24 hours says the sky will remain generally cloudy with light to moderate rain or thundershowers. The maximum temperature is expected to be around 33°C, while the minimum may be about 28°C.

“The low pressure area over west, central and adjoining northwest Bay of Bengal, north Andhra Pradesh south Odisha coasts persisted at 0830 hrs IST of today, the 13th September, 2025. The associated cyclonic circulation extended up to 5.8 km above mean sea level tilting southwestwards with height. It is likely to move west-northwestwards across south Odisha and adjoining north Andhra Pradesh and south Chhattisgarh during the next two days,” said IMD.

The monsoon trough at mean sea level passes through Sri Ganganagar, Rohtak, Seoni, Rajnandgaon and thence to centre of low pressure area over west, central and adjoining northwest Bay of Bengal, north Andhra Pradesh-south Odisha coasts.

According to IMD, the upper air cyclonic circulation over northeast Jharkhand and neighbourhood now lies over southwest Bihar and adjoining Jharkhand at 0.9 km above mean sea level.

The low pressure area, according to IMD, will have no direct impact over West Bengal. “However, under the presence of above meteorological conditions and strong moisture incursion, widespread light to moderate rainfall with isolated heavy to very heavy rainfall activity very likely over the districts of North Bengal. Light to moderate rainfall at many places with thunderstorm and lightning activity very likely over districts of South Bengal,” said IMD.
