IMD issues heavy rain warning in West Bengal, yellow alert for Kolkata

The India Meteorological Department (IMD) has issued a warning of heavy rainfall in southern West Bengal over the next three days, from September 24 to 26. The rains are expected due to a low-pressure area forming over the northeast Bay of Bengal, which is associated with cyclonic circulation. The IMD has also cautioned people about thunderstorms, strong winds, waterlogging, and traffic congestion in affected areas.

According to the IMD, light to moderate rainfall will prevail across South Bengal, with isolated heavy rainfall at some places. The low-pressure system is likely to move northwest towards the northwestern part of the Bay of Bengal, maintaining wet conditions in the region. The IMD has advised people to remain alert and take precautions during intense rain spells.

Orange and yellow alerts in several districts

The IMD has issued a mix of orange and yellow alerts for different districts in West Bengal. An orange alert has been issued for South 24 Parganas, which may experience heavy rainfall. Yellow alerts have been sounded for Kolkata, Paschim Medinipur, Bankura, Purulia, Birbhum, North 24 Parganas, Murshidabad, and Malda.

For September 23, the IMD predicts heavy rainfall of 7–11 cm in East and West Midnapore, South 24 Parganas, and Bankura. These rains will be accompanied by thunderstorms, lightning, and gusty winds reaching speeds of 30–40 kmph. From September 24 to 26, light to moderate rain is expected over most parts of South Bengal, with thunderstorms in a few areas. Rainfall is expected to decrease from September 27, with only isolated light to moderate showers.

Authorities have warned that low-lying areas and underpasses may experience severe waterlogging and flooding. Drivers are advised to be careful during heavy rains, as low visibility could lead to traffic jams. People are also warned to avoid standing near electric poles during rain and to take shelter in safe areas.

Impact on life and festivities

The weather warning comes just before Durga Puja, a major festival in West Bengal. Pandals and festive setups have already been made across the state, and heavy rain may affect public gatherings and celebrations. Authorities are preparing to manage traffic and ensure safety during the festival period.

Fishermen have also been advised not to venture into the sea along and off the West Bengal coast until September 27 due to rough sea conditions caused by the low-pressure system. The IMD has urged all residents to stay informed through official weather updates and to follow safety instructions to avoid accidents or injuries.

The southern districts of West Bengal are particularly vulnerable to heavy rain due to their geography, with rivers and drainage systems already under stress during monsoon season. People living in flood-prone areas are advised to keep emergency supplies ready and remain vigilant about local warnings and advisories.

The IMD’s warning emphasizes that the upcoming days may bring sudden intense rain, gusty winds, and possible lightning strikes. Authorities have urged residents to avoid unnecessary travel during peak rainfall periods and to stay indoors as much as possible. Schools, offices, and public transport authorities are being alerted to prepare for disruptions due to waterlogging and traffic congestion.

The forecast suggests that this period of rainfall may impact daily life, agriculture, and urban infrastructure. Farmers in South Bengal have been advised to protect crops and manage water levels carefully to minimize damage. Similarly, city residents are being warned to prepare for temporary waterlogging in streets and residential areas.

By September 27, the low-pressure system is expected to weaken, leading to lighter showers and a gradual improvement in weather conditions. Until then, residents of West Bengal, especially in South Bengal and Kolkata, are advised to follow updates from the IMD and local authorities.
