Quick Revision: Very Severe Cyclonic Storms (VSCS) are classified by the IMD with sustained wind speeds of 118–165 kmph, requiring immediate evacuation, structural reinforcement, and multi-agency coordination for effective disaster mitigation.

Why is this in the news?

The Andhra Pradesh State Disaster Management Authority (APSDMA) has initiated large-scale evacuation and preparedness measures in coastal districts ahead of the anticipated landfall of a Very Severe Cyclonic Storm (VSCS) between Machilipatnam and Visakhapatnam on October 28, 2026. With wind speeds projected to reach 140 kmph and potential impacts on 8 districts, this event underscores the critical importance of India’s institutional disaster management framework, including the roles of the India Meteorological Department (IMD), NDRF, SDRF, and district-level authorities in mitigating cyclone-related risks.

Background

• The Bay of Bengal is one of the most cyclone-prone regions globally, with an average of 5-6 cyclonic storms forming annually, of which 2-3 typically intensify into severe cyclones.
• Andhra Pradesh’s coastline, spanning approximately 974 km, is highly vulnerable to cyclonic storms due to its geographical exposure and low-lying terrain in deltaic regions.
• Between 1971 and 2026, 61 cyclonic storms have made landfall on the Andhra Pradesh coast, with 10 classified as Very Severe Cyclonic Storms (VSCS), including Hudhud (2014) and Titli (2018).
• The National Disaster Management Authority (NDMA), established under the Disaster Management Act, 2005, provides the legal and institutional framework for disaster management in India, mandating a multi-tiered response system involving central, state, and district agencies.
• The Andhra Pradesh State Disaster Management Authority (APSDMA) functions as the nodal agency for disaster preparedness, response, and recovery, coordinating with the National Disaster Response Force (NDRF) and State Disaster Response Force (SDRF).
• Cyclone classification by the India Meteorological Department (IMD) follows the Saffir-Simpson Hurricane Wind Scale, with categories ranging from Depression to Super Cyclonic Storm based on sustained wind speeds and potential damage.

What is a Very Severe Cyclonic Storm (VSCS)?

• A Very Severe Cyclonic Storm (VSCS) is a meteorological phenomenon classified by the India Meteorological Department (IMD) when sustained wind speeds range between 118 kmph and 165 kmph, accompanied by torrential rainfall and storm surges.
• VSCSs are capable of causing extensive structural damage to kutcha (non-permanent) and semi-permanent structures, uprooting trees, disrupting power and communication networks, and triggering flash floods and landslides in vulnerable regions.
• The IMD uses a five-tier classification system for cyclones: Depression (<63 kmph), Deep Depression (63–87 kmph), Cyclonic Storm (88–117 kmph), Severe Cyclonic Storm (118–165 kmph), and Very Severe Cyclonic Storm (>165 kmph).
• Cyclone formation in the Bay of Bengal is influenced by warm sea surface temperatures (above 26°C), low vertical wind shear, and the presence of a pre-existing low-pressure system, often during the post-monsoon season (October–December).
• The IMD issues colour-coded alerts (Green, Yellow, Orange, Red) to indicate the severity of impending cyclones, with Red alerts signifying the highest risk and prompting large-scale evacuations and emergency responses.
• Storm surges, a rise in seawater level due to low atmospheric pressure and strong winds, are a major hazard during cyclones, particularly in low-lying coastal districts like those in Andhra Pradesh.
• The National Disaster Response Force (NDRF) and State Disaster Response Forces (SDRF) are deployed for search and rescue, relief operations, and restoration of critical infrastructure during and after cyclones.
• Post-cyclone recovery involves damage assessment, restoration of utilities, provision of relief materials, and psychological support to affected communities, coordinated by district disaster management authorities.

Key Features

Feature	Significance
Forecasted landfall zone	Determines the spatial distribution of impact, guiding evacuation and resource allocation in districts such as Krishna, West Godavari, and Visakhapatnam.
Wind speed projections (140 kmph)	Indicates the potential for structural damage to infrastructure, particularly to kuchha houses and standing vegetation, necessitating preemptive reinforcement measures.
Evacuation protocols	Ensures systematic relocation of vulnerable populations to cyclone shelters, reducing human casualties and facilitating post-disaster relief operations.
State Disaster Response Force (SDRF) and National Disaster Response Force (NDRF) deployment	Enhances the State’s capacity for rapid response, search-and-rescue, and medical aid during the cyclone’s landfall and aftermath.
Cyclone shelter preparedness	Involves sanitation, stocking of essential commodities, and crowd management, ensuring habitability and reducing disease outbreaks post-landfall.

Why it Matters

Disaster Risk Reduction

• Andhra Pradesh’s proactive measures align with the Sendai Framework for Disaster Risk Reduction (2015–2030), emphasizing early warning systems and community preparedness to mitigate cyclone impacts.
• The deployment of SDRF and NDRF battalions reflects India’s institutional framework for disaster management under the Disaster Management Act, 2005.
• Evacuation protocols demonstrate adherence to the National Disaster Management Plan (NDMP), which prioritizes life-saving interventions during cyclonic events.

Climate Resilience

• The increasing frequency of cyclonic storms in the Bay of Bengal underscores the need for climate-resilient infrastructure and urban planning in coastal districts.
• Historical data (61 cyclones since 1971) highlights the vulnerability of Andhra Pradesh’s coastline, necessitating long-term adaptation strategies such as mangrove restoration and coastal zone regulation.

Institutional Coordination

• The role of the India Meteorological Department (IMD) in forecasting and the APSDMA in coordination exemplifies multi-agency collaboration in disaster management.
• The requisitioning of additional NDRF battalions demonstrates inter-state resource sharing, a critical component of the NDMP’s collaborative approach.

Humanitarian Impact

• The cyclone’s potential to disrupt livelihoods in fishing and agriculture sectors necessitates post-disaster economic rehabilitation measures under the Pradhan Mantri Fasal Bima Yojana (PMFBY) and other welfare schemes.
• Evacuation and shelter management address the immediate humanitarian needs of displaced populations, including women, children, and the elderly.

Challenges

1. Predictability of Cyclone Intensity

• Rapid intensification of cyclones challenges early warning systems, requiring real-time monitoring and adaptive response strategies.
• The transition from a deep depression to a cyclonic storm within hours necessitates agile decision-making by disaster management authorities.

2. Logistical Constraints in Evacuation

• High population density in coastal districts complicates the evacuation process, particularly in urban areas like Visakhapatnam and Machilipatnam.
• Transportation and communication disruptions during landfall may hinder the movement of relief teams and supplies.

3. Infrastructure Vulnerability

• Kuchha houses and informal settlements are highly susceptible to damage, exacerbating post-disaster displacement and homelessness.
• Critical infrastructure such as power lines, water supply systems, and healthcare facilities may face operational disruptions.

5. Resource Allocation Under Uncertainty

• The need for additional NDRF battalions and cyclone shelters strains State resources, particularly in fiscally constrained scenarios.
• Balancing immediate relief with long-term recovery planning requires careful prioritization of funds and materials.

Challenges — UPSC Perspective

Issue	Concern
Rapid intensification of cyclones	Limits the time available for evacuation and resource mobilization, increasing the risk of casualties.
Urban evacuation bottlenecks	High-density coastal cities face challenges in managing large-scale evacuations due to limited shelter capacity and traffic congestion.
Damage to critical infrastructure	Disruptions to power, water, and healthcare services can prolong recovery and exacerbate humanitarian crises.
Post-disaster disease outbreaks	Flooding and poor sanitation in shelters create conditions for epidemics, particularly in densely populated areas.
Inter-agency coordination gaps	Delays in decision-making or resource sharing between State and Central agencies can undermine response effectiveness.

Government Initiatives — Must-Memorise for Prelims

• National Disaster Management Plan (NDMP)
• Pradhan Mantri Fasal Bima Yojana (PMFBY)
