The India Meteorological Department (IMD) issued an urgent high-level weather warning across the eastern coastal belt after a deep depression over the west-central and adjoining northwest Bay of Bengal made landfall along the north Andhra Pradesh and south Odisha coasts. Bringing gale-force winds reaching speeds up to 75 km/h alongside torrential downpours, the storm system disrupted localized regional transit networks, power transmission lines, and maritime fishing activities across coastal districts. In response to the intensifying coastal threat, state disaster response management teams, alongside emergency personnel from the National Disaster Response Force (NDRF), were deployed to evacuate low-lying coastal communities, clear fallen debris, and establish temporary disaster shelter camps. Environmental scientists and regional hydrologists noted that sudden shifts in sea surface temperatures in the Bay of Bengal have increased the frequency of severe coastal depressions, reinforcing the need for continuous urban drainage upgrades and modernized early-warning storm systems. Local municipal authorities urged coastal residents to remain indoors, suspend marine operations, and follow real-time advisory updates as emergency response teams work to mitigate local flood risks.

Bay of Bengal Weather System Crosses Coast Near Kalingapatnam

The India Meteorological Department (IMD) placed multiple coastal and interior districts of North Andhra Pradesh, Odisha, and adjoining Telangana and South Chhattisgarh on high alert as a deep depression over the Westcentral Bay of Bengal crossed the eastern coastline. Striking between Visakhapatnam and Gopalpur—close to the southwest of Kalingapatnam—the front sector of the weather system brought heavy to extremely heavy downpours accompanied by squally winds gusting up to 75 kmph.

Torrential Rains Disrupt Infrastructure and Prompt Evacuations

The coastal landfall triggered extremely heavy precipitation exceeding 21 cm across southern Odisha and coastal Andhra districts. In Odisha, the state government deployed National Disaster Response Force (NDRF) and Odisha Disaster Rapid Action Force (ODRAF) teams across vulnerable districts including Ganjam, Gajapati, Rayagada, Koraput, and Malkangiri, evacuating over 5,000 residents from low-lying areas to flood shelters. District administration officials in Srikakulam, Parvathipuram Manyam, Vizianagaram, and Visakhapatnam ordered school closures and set up 24x7 control rooms to manage power line outages and fallen trees blocking highway corridors.

IMD bulletins warned of low-to-moderate flash flood risks across watershed areas due to fully saturated soils. The weather agency advised complete suspension of fishing operations along and off the Andhra Pradesh, Odisha, and West Bengal coasts through September 24, noting that sea conditions will remain "rough to very rough".

Forecast for Interior Movement and Gradual Weakening

According to IMD meteorologists, after completing its coastal entry, the deep depression is projected to continue moving west-northwestwards across South Odisha and South Chhattisgarh. The system is expected to maintain its deep depression intensity for 12 hours before gradually weakening into a standard low-pressure area over interior central India.

However, heavy rainfall warnings remain active for Telangana, Vidarbha, and eastern Madhya Pradesh through September 25 and 26 as the remnants of the moisture-laden system trek inland. Disaster management authorities have urged citizens in low-lying and hilly regions to avoid unnecessary travel, stay clear of dilapidated structures, and follow local municipal safety advisories.
