A deep depression over the Bay of Bengal is moving toward the north Andhra Pradesh and south Odisha coasts, bringing the threat of heavy to extremely heavy rainfall, strong winds and rough sea conditions to several coastal and inland areas.

The India Meteorological Department (IMD) said the system was moving west-northwestward and was expected to cross the coast near Kalingapatnam between Visakhapatnam and Gopalpur during the night of September 23. The latest IMD bulletin places the system over the west-central and adjoining northwest Bay of Bengal.

Deep Depression Moves Toward the Coast

According to the latest meteorological assessment, the system was moving at around 7 kmph. It was located approximately 100 kilometres east-southeast of Kalingapatnam in Andhra Pradesh and around 150 kilometres south of Gopalpur in Odisha in the IMD’s latest bulletin.

The weather system is expected to continue moving west-northwestward before crossing the north Andhra Pradesh–south Odisha coast as a deep depression.

The approaching system has prompted heightened monitoring by weather authorities and local administrations, particularly in areas vulnerable to flooding, landslides and disruption caused by strong winds.

Heavy Rainfall Expected

The major threat associated with the system is rainfall.

The IMD has forecast widespread rain and thunderstorms across affected coastal areas, with heavy to very heavy rainfall expected in parts of Odisha and Andhra Pradesh. Some locations could experience extremely heavy rainfall.

Other states, including Telangana and Chhattisgarh, are also expected to receive significant rainfall under the influence of the system.

Heavy rainfall over a short period can rapidly increase water levels in rivers and drainage channels. Low-lying urban and rural areas may therefore face temporary waterlogging or flooding.

Strong Winds Along the Coast

The weather system is also producing strong winds over the Bay of Bengal.

The IMD’s coastal bulletin indicates that winds along parts of the south Odisha coast could reach 30–35 knots, with gusts up to 45 knots. Sea conditions are expected to become very rough to high in affected areas.

Along the north Andhra coast, squally winds of around 25–30 knots, with higher gusts, have also been forecast.

These conditions can make marine activity hazardous and can affect fishing operations, small boats and coastal transportation.

Odisha Takes Precautionary Measures

Authorities in Odisha have already begun precautionary measures because of the expected rainfall.

Several districts have announced school closures as the state prepares for worsening weather conditions. Local authorities have also been monitoring vulnerable areas and preparing for possible disruption from heavy rain and strong winds.

In parts of southern Odisha, heavy rain and strong winds have already affected road connectivity. Reports indicate that trees were uprooted in Ganjam and Gajapati districts, temporarily blocking roads before authorities cleared the debris.

Flood and Landslide Risk

The combination of heavy rainfall and saturated ground can increase the risk of flash flooding and landslides, particularly in hilly and poorly drained areas.

Residents living near rivers, streams and low-lying locations are likely to face greater exposure if rainfall becomes prolonged or exceptionally intense.

Authorities are therefore monitoring rainfall patterns and water levels while emergency teams remain prepared to respond if conditions deteriorate.

No Confirmed Cyclone at This Stage

Despite speculation about whether the system could become a named cyclone, the IMD’s current assessment describes it as a deep depression.

The next cyclone name on the regional naming list would be “Arnab,” but the presence of a name on the list does not mean that the current system has reached cyclone intensity.

The immediate weather threat is therefore being assessed on the basis of the deep depression’s rainfall, wind and sea impacts rather than on whether it receives cyclone classification.

Impact Could Extend Beyond the Coast

The effects of the system are not expected to remain limited to the immediate coastal zone.

Rainfall associated with the depression can spread inland as the system moves across the region. Andhra Pradesh, Odisha, Telangana and parts of central and eastern India may experience varying levels of rainfall depending on the system’s exact track and intensity.

For communities, heavy rainfall can affect road traffic, agriculture, electricity infrastructure and everyday activities.

Authorities Continue Monitoring

The IMD is continuing to issue updates as the system approaches the coast. Weather conditions can change quickly, making updated forecasts particularly important during the landfall period.

People in affected districts are advised to follow instructions issued by local authorities and weather agencies, particularly regarding travel, fishing and movement through areas vulnerable to flooding.

Residents should also avoid entering flooded roads or waterways, where rapidly moving water can pose serious risks even when the water does not appear deep.

A Major Weather Event for Eastern India

The deep depression represents a significant weather event for eastern India, particularly because it combines heavy rainfall with strong coastal winds and rough seas.

The immediate focus for authorities is on reducing exposure to dangerous weather, protecting vulnerable communities and responding quickly to any flooding or infrastructure damage.

As the system moves toward the coast, further IMD updates will determine how rainfall and wind conditions evolve across Andhra Pradesh, Odisha and neighbouring states.

For now, the weather system remains a major rainfall threat, with the most significant impacts expected around the north Andhra Pradesh and south Odisha coastal belt.
