Quick Revision: Cyclone ‘Arnab’ is classified as a Very Severe Cyclonic Storm (VSCS), expected to make landfall near Bapatla–Visakhapatnam on 28 October 2026, necessitating the evacuation of 48,000 people in Odisha under the State Disaster Response Fund framework.

Why is this in the news?

The Odisha government has initiated large-scale evacuation of 48,000 people across eight districts in anticipation of the very severe cyclonic storm ‘Arnab’, which is projected to make landfall near the Andhra Pradesh–Yanam coast on 28 October 2026. This proactive measure underscores India’s evolving cyclone preparedness framework, integrating meteorological forecasting, multi-agency coordination, and community-based disaster risk reduction strategies.

Background

• Tropical cyclones are among the most destructive natural hazards in India, particularly affecting the eastern coast (Odisha, Andhra Pradesh, West Bengal) and the western coast (Gujarat, Maharashtra, Kerala).
• Odisha has historically been one of the most cyclone-prone states in India, with major cyclones such as Phailin (2013), Hudhud (2014), Titli (2018), and Fani (2019) causing significant loss of life and economic damage.
• The Indian Meteorological Department (IMD) classifies cyclones based on wind speed: Cyclonic Storm (62–87 km/h), Severe Cyclonic Storm (88–117 km/h), Very Severe Cyclonic Storm (118–165 km/h), and Extremely Severe Cyclonic Storm (166–220 km/h).
• The Disaster Management Act, 2005, provides the legal and institutional framework for disaster management in India, mandating the establishment of the National Disaster Management Authority (NDMA) and State Disaster Management Authorities (SDMAs).
• The National Disaster Response Force (NDRF) and State Disaster Response Forces (SDRF) are key operational agencies for rescue and relief during cyclones.
• The State Disaster Response Fund (SDRF) and National Disaster Response Fund (NDRF) are critical financial instruments for immediate relief and rehabilitation.

What is a Tropical Cyclone and How is it Classified?

• A tropical cyclone is a rapidly rotating storm system characterised by a low-pressure centre, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.
• Cyclones form over warm ocean waters near the equator, drawing energy from the sea surface and intensifying as they move over warmer waters.
• The IMD classifies cyclones based on maximum sustained surface wind speed: Cyclonic Storm (62–87 km/h), Severe Cyclonic Storm (88–117 km/h), Very Severe Cyclonic Storm (118–165 km/h), and Extremely Severe Cyclonic Storm (166–220 km/h).
• Cyclones are further categorised as ‘Deep Depression’ (52–61 km/h) and ‘Super Cyclonic Storm’ (>220 km/h) based on intensity.
• The Saffir-Simpson Hurricane Wind Scale, though used globally, is not adopted by IMD; instead, IMD uses the above classification for Indian Ocean cyclones.
• Cyclones are named by regional bodies such as the World Meteorological Organization (WMO) to facilitate communication and reduce confusion; names are pre-decided and rotated periodically.
• The Bay of Bengal and Arabian Sea together account for approximately 7% of the world’s tropical cyclones, with the Bay of Bengal being more prone due to its geography and warm waters.

Key Features

Feature	Significance
Evacuation of 48,000 people across eight districts	Mitigates human casualties by relocating vulnerable populations to cyclone-resistant shelters before landfall.

Why it Matters

Disaster Preparedness and Mitigation

• Demonstrates Odisha’s institutional capacity in cyclone risk reduction, building on lessons from past cyclones like Phailin (2013) and Fani (2019).
• Highlights the integration of early warning systems with evacuation protocols to minimise loss of life.
• Showcases the role of multi-agency coordination (ODRAF, NDRF, fire services) in large-scale disaster response.

Institutional Framework

• Illustrates the functioning of the State Disaster Management Authority (SDMA) under the Disaster Management Act, 2005.
• Emphasises the role of the India Meteorological Department (IMD) in providing critical meteorological inputs for disaster management.
• Demonstrates the fiscal and logistical preparedness of state governments in disaster risk financing.

Vulnerability and Resilience

• Exposes the geographical and socio-economic vulnerabilities of coastal and southern Odisha districts to cyclonic storms.
• Underscores the importance of resilient infrastructure, including cyclone shelters and early warning dissemination systems.
• Highlights the need for community awareness and training in disaster preparedness and response.

Challenges

1. Logistical Constraints in Evacuation

• Limited transport infrastructure in remote districts like Malkangiri and Nabarangpur may delay evacuation.
• Ensuring safe shelter for evacuees, particularly vulnerable groups such as the elderly, disabled, and livestock.
• Maintaining supply chains for food, water, and medical aid during adverse weather conditions.

Way Forward

• Strengthen inter-agency coordination between ODRAF, NDRF, and local authorities for seamless evacuation and relief operations.
• Enhance community-based disaster preparedness through regular drills, awareness campaigns, and mock evacuation exercises in vulnerable districts.
• Invest in resilient infrastructure, including cyclone shelters, early warning systems, and decentralised relief storage facilities.
• Improve real-time data sharing and forecasting models to reduce uncertainties in cyclone tracking and impact assessment.
• Develop contingency plans for post-disaster recovery, including livelihood restoration and psychological support for affected populations.
• Integrate climate change adaptation strategies into disaster risk reduction plans to address long-term vulnerabilities.
• Leverage technology for efficient resource allocation, including GIS mapping for evacuation routes and shelter locations.
• Ensure transparent and timely disbursement of disaster relief funds to prevent bottlenecks in emergency response.
