The Indian Meteorological Department (IMD) has issued an alert predicting heavy to very heavy rainfall across several northeastern and eastern states in the coming week. States including Assam, West Bengal, Sikkim, Meghalaya, and parts of Bihar and Odisha are expected to experience significant downpours due to an active monsoon system. The IMD’s forecast warns that the heavy rains could lead to localized flooding, waterlogging, and landslides, particularly in hilly areas and regions near rivers.
Weather System Driving the Rainfall
The current weather patterns indicate the strengthening of the monsoon trough, which is expected to remain active across the eastern and northeastern parts of the country. A low-pressure system over the Bay of Bengal has also intensified, contributing to increased moisture and driving heavy rains into Assam, West Bengal, and neighboring states. This low-pressure system, in combination with cyclonic circulation, is pushing humid air inland, creating the ideal conditions for widespread rainfall.
According to the IMD, Assam and West Bengal are likely to receive some of the heaviest rainfall, with certain regions bracing for 100 mm to 200 mm of rain over the next few days. Along with these states, Sikkim, Meghalaya, Arunachal Pradesh, and Nagaland are expected to experience significant rainfall, with localized heavy showers possible.
Flooding Concerns in Assam and West Bengal
In Assam, the threat of flooding is particularly concerning. The state has a long history of severe floods during the monsoon season, largely due to the Brahmaputra River and its tributaries, which tend to overflow during heavy rainfall. The IMD has warned that the river could swell beyond its danger levels, especially in the districts of Dhemaji, Lakhimpur, and Majuli.
West Bengal is also expected to see heavy rains across the northern districts, especially in Darjeeling, Jalpaiguri, and Alipurduar. The IMD has cautioned that these areas are prone to landslides during intense rainfall, posing a risk to local communities. Additionally, districts in southern West Bengal, including Kolkata and the surrounding areas, could experience waterlogging and traffic disruptions due to the heavy rains. Urban centers like Kolkata often face challenges with drainage systems during intense downpours, leading to flooding on roads and residential areas.
In response to the forecast, state governments have begun issuing advisories and preparing for potential relief efforts. Local authorities in Assam and West Bengal are closely monitoring water levels in rivers and reservoirs, while disaster management teams have been put on high alert. Temporary shelters are being prepared in flood-prone areas, and people living near riverbanks have been advised to move to safer locations.
Impact on Sikkim and Northeast India
The hill state of Sikkim, which is already prone to landslides during the monsoon, could face additional risks due to the predicted heavy rainfall. The IMD has issued warnings of potential landslides along key highways, particularly on the National Highway-10, which connects Sikkim to West Bengal. Road closures and disruptions in transportation are likely if heavy rains trigger landslides in the hilly areas of the state.
Meghalaya and Arunachal Pradesh, which are also expected to receive substantial rainfall, face similar challenges. Both states are known for their high rainfall during the monsoon season, but heavy, sustained downpours often lead to flash floods and landslides, especially in areas with steep terrain. The IMD has advised caution for travelers and residents in these regions, urging people to avoid unnecessary travel during periods of intense rainfall.
Bihar and Odisha: Increasing Rainfall Intensity
Bihar and Odisha are also expected to see increased rainfall activity over the next week, though the intensity is expected to vary. The northern districts of Bihar are likely to experience heavy rainfall, with localized flooding possible in low-lying areas. Rivers such as the Ganga, Kosi, and Gandak, which flow through Bihar, may experience rising water levels. The IMD has highlighted concerns about waterlogging in urban areas and has urged local administrations to ensure proper drainage facilities are in place.
In Odisha, while heavy rainfall is expected, it is less likely to be as intense as in the northeastern states. However, the state’s coastal regions could experience isolated heavy downpours, particularly in districts like Ganjam, Puri, and Khurda.
Precautionary Measures and Preparedness
As heavy rainfall is expected to continue in these regions over the next several days, authorities are advising residents to remain vigilant. People living in flood-prone areas have been advised to stay updated with weather alerts and to move to safer locations if necessary. In Assam and West Bengal, the governments have activated their flood relief protocols, ensuring that rescue and relief teams are ready to respond in case of emergencies.
The National Disaster Response Force (NDRF) is on standby in Assam, West Bengal, and Sikkim, prepared to assist with evacuation efforts and provide aid in areas affected by floods or landslides. Fishermen along the coastal regions of Odisha and West Bengal have been advised not to venture into the sea due to rough conditions triggered by the low-pressure system over the Bay of Bengal.
The IMD’s prediction of heavy rainfall in Assam, West Bengal, and other northeastern states highlights the ongoing challenges posed by the monsoon season. While the rains are crucial for agriculture and water supply, the risk of floods, landslides, and infrastructure damage requires careful monitoring and preparedness. As the situation unfolds, authorities in these states are on high alert, ready to respond to any emergencies and minimize the impact on vulnerable communities.
