Quick Revision: The ‘Zero Casualty’ approach in cyclone management prioritises early warning dissemination, community evacuation, and inter-agency coordination, with Odisha’s preparedness for the impending cyclonic storm serving as a model for other coastal states.

Why is this in the news?

The Odisha government has initiated comprehensive cyclone preparedness measures, including the closure of educational institutions and the deployment of disaster response teams, in anticipation of a cyclonic storm expected to make landfall on October 28, 2026. This proactive approach underscores the state’s commitment to the ‘Zero Casualty’ doctrine in disaster management. The impending event highlights the critical role of early warning systems, inter-agency coordination, and community awareness in mitigating the impact of cyclonic disasters.

Background

• The Bay of Bengal is a primary cyclone genesis basin, accounting for approximately 58% of India’s cyclonic storms, with peak activity during the post-monsoon season (October–December).
• Odisha, with its 480 km coastline, is one of India’s most cyclone-prone states, having faced 11 cyclones of severe intensity (wind speeds ≥ 118 km/h) since 1970, including the devastating Super Cyclone of 1999.
• The India Meteorological Department (IMD) operates a Cyclone Warning System (CWS) with four-stage warnings: (1) Cyclone Watch, (2) Cyclone Alert, (3) Cyclone Warning, and (4) Post-Cyclone Watch, ensuring timely dissemination to vulnerable regions.
• The National Disaster Management Authority (NDMA) was constituted in 2005 under the Disaster Management Act, 2005, to coordinate disaster response and preparedness across states, including the formulation of the National Cyclone Risk Mitigation Project (NCRMP).

What is a Cyclonic Storm and How is it Classified?

• A cyclonic storm is a meteorological phenomenon characterised by a low-pressure system over tropical or subtropical waters, with organised convection and a defined circulation pattern around a central eye.
• The India Meteorological Department (IMD) classifies cyclonic disturbances in the Indian Ocean basin into four categories based on wind speed: (1) Depression (wind speed 31–49 km/h), (2) Deep Depression (50–61 km/h), (3) Cyclonic Storm (62–88 km/h), and (4) Severe Cyclonic Storm (89–117 km/h), with further classifications for Very Severe (118–166 km/h) and Extremely Severe Cyclonic Storms (167–221 km/h).
• Cyclones in the Bay of Bengal typically form due to warm sea surface temperatures (≥ 26.5°C), high humidity, and low vertical wind shear, conditions that are prevalent during the post-monsoon season (October–December).
• The life cycle of a cyclone includes four stages: (1) Formation (low-pressure area), (2) Intensification (depression to cyclonic storm), (3) Maturity (severe cyclonic storm), and (4) Decay (landfall and dissipation), with landfall being the most destructive phase due to storm surges, high winds, and torrential rainfall.
• Storm surges, the abnormal rise in sea level due to cyclonic winds, are the primary cause of coastal flooding and account for the majority of cyclone-related fatalities in India.
• The IMD’s Cyclone Warning Division issues bulletins every three hours during active cyclones, providing critical data on track, intensity, and expected landfall time to state governments and disaster management authorities.
• The National Disaster Response Force (NDRF) and State Disaster Response Forces (SDRF) are deployed preemptively to conduct evacuations, set up relief camps, and manage post-cyclone operations, with the NDRF currently having 12 battalions strategically located across cyclone-prone states.

Key Features

Feature	Significance
Intensification of low-pressure area into cyclonic storm	Demonstrates the meteorological progression of cyclones over the Bay of Bengal, critical for disaster forecasting and preparedness.
Red alerts issued by IMD for coastal districts	Ensures timely dissemination of high-risk warnings to enable evacuation and resource allocation in vulnerable regions.
Closure of educational institutions in five districts	A preventive measure to ensure student safety and reduce public movement during peak cyclone impact.
Deployment of disaster response teams on high alert	Reflects institutional readiness to execute rapid relief operations, including search-and-rescue and medical aid.
Fisheries advisory restricting sea ventures	Mitigates risks to coastal communities dependent on marine livelihoods by preventing exposure to hazardous sea conditions.

Why it Matters

Disaster Management

• Illustrates the phased approach of cyclone preparedness, from early warning to ground-level execution, aligning with the Sendai Framework for Disaster Risk Reduction.
• Highlights the role of the India Meteorological Department (IMD) in providing accurate and timely forecasts to inform state-level responses.
• Demonstrates Odisha’s established disaster response protocols, built on lessons from past cyclones such as Phailin (2013) and Fani (2019).

Institutional Coordination

• Showcases the collaborative mechanism between the IMD, state disaster management authorities, and local administration in crisis mitigation.
• Underscores the importance of inter-state coordination, as Andhra Pradesh also issues red alerts for districts likely to be affected.
• Emphasises the role of the National Disaster Response Force (NDRF) and State Disaster Response Forces (SDRF) in pre-positioning teams for rapid deployment.

Socio-Economic Impact

• Exposes the vulnerability of coastal districts to extreme weather events, particularly in southern Odisha, where livelihoods are tied to agriculture and fisheries.
• Raises concerns about potential disruptions to education and public services, necessitating contingency plans for remote learning and essential service continuity.
• Highlights the economic cost of cyclone preparedness, including resource allocation for relief, rehabilitation, and infrastructure repair.

Challenges — UPSC Perspective

Issue	Concern
Forecast Uncertainty	Variability in cyclone intensity and landfall predictions may lead to either over-preparedness or under-preparedness.
Evacuation Bottlenecks	Narrow roads, traffic congestion, and inadequate transport facilities in coastal districts hinder swift evacuation.
Shelter Management	Inadequate or poorly maintained cyclone shelters may fail to accommodate displaced populations safely.
Health Risks	Post-cyclone conditions increase the likelihood of vector-borne diseases, respiratory issues, and injuries.
Data Gaps	Lack of granular data on vulnerable populations, such as migrant workers or elderly residents, complicates targeted relief efforts.

Way Forward

• Strengthen inter-state coordination between Odisha and Andhra Pradesh to ensure seamless evacuation and resource sharing.
• Conduct mock drills and community awareness campaigns in high-risk districts to familiarise residents with evacuation routes and shelter protocols.
• Pre-position essential supplies, including food, medical kits, and potable water, in cyclone-prone districts to ensure rapid distribution.
• Enhance real-time monitoring of critical infrastructure (e.g., power grids, telecom networks) to minimise disruptions during cyclone landfall.
• Integrate climate-resilient infrastructure in coastal urban planning, such as elevated roads and flood-resistant buildings.
• Establish rapid assessment teams to evaluate damage and prioritise relief efforts immediately after cyclone passage.
• Promote sustainable livelihood alternatives for coastal communities to reduce dependency on high-risk sectors like fisheries during cyclone seasons.
