A deep depression moving toward the West Bengal-Odisha coast is expected to cause heavy rainfall across southern districts until July 28. Fishermen have been advised against venturing into the sea due to rough conditions and strong winds. The weather system may disrupt local transport, agricultural activities, and logistics in coastal areas.
Detailed Coverage
A deep depression currently positioned over the Bay of Bengal is heading toward the coast between West Bengal and Odisha, bringing forecasts of heavy rainfall to several southern districts. The India Meteorological Department (IMD) expects the weather system to reach the coast by Monday afternoon, which may lead to significant precipitation through July 28.
Impact on Coastal and Inland Districts
Coastal regions such as South 24 Parganas and Purba Medinipur are bracing for heavy downpours that are likely to persist through Tuesday. Inland districts including Paschim Medinipur and Jhargram are also under observation for very heavy rainfall. Further north, the IMD has indicated that the sub-Himalayan regions, including Darjeeling, Jalpaiguri, and Cooch Behar, could experience isolated heavy rain that may continue as late as August 1.
Marine and Infrastructure Risks
The weather system is bringing strong winds with speeds reaching 55 to 65 kmph, potentially gusting up to 75 kmph. Due to these rough sea conditions, authorities have issued a strict advisory for fishermen to avoid the northwest Bay of Bengal and the West Bengal coast until July 29. From an investor perspective, such weather disruptions often impact logistics, supply chain operations, and port activities in the region. Areas like Haldia and the Sagar Island region, which recorded 29 mm and 52 mm of rainfall respectively in the 24 hours leading up to Monday morning, may see localized flooding or delays in commodity movement.
Monitoring Potential Disruptions
Investors with exposure to companies dependent on port operations, regional logistics, or agricultural supply chains in South Bengal may track the progress of this depression. While intermittent moderate rain is expected in Kolkata, any significant escalation in rainfall intensity could affect urban infrastructure and workforce attendance. The primary monitorables for the next 48 hours include the exact landfall location, the duration of the squally winds, and whether the heavy rain extends into the agricultural heartlands, which could influence short-term output or transport costs for regional businesses.
