As Cyclone Dana approached the eastern coast of India, the states of Odisha and West Bengal faced a series of preparations and warnings aimed at mitigating the potential damage. Cyclones in the Bay of Bengal have historically been severe, bringing widespread impacts to both rural and urban regions, and Cyclone Dana is no exception. This article covers Cyclone Dana's impact on Odisha and West Bengal, the steps taken by authorities to protect communities, and what future preparedness might look like.

Understanding Cyclone Dana
Cyclone Dana formed in the Bay of Bengal, known as one of the most cyclone-prone areas in the world. The unique climatic and geographical conditions in this region make it especially vulnerable to powerful cyclonic storms, especially during pre-monsoon and post-monsoon seasons. After forming in the Bay of Bengal, Cyclone Dana quickly intensified, prompting warnings and advisories for India’s east coast.
Weather Warnings and Government Alerts
The Indian Meteorological Department (IMD) played a crucial role in tracking Cyclone Dana and alerting local authorities and residents. By issuing color-coded alerts, the IMD guided state governments, agencies, and citizens on the necessary precautionary measures. Red alerts indicated the highest danger levels, while yellow and orange alerts provided early warnings for areas expected to experience heavy rain and strong winds.
As Cyclone Dana neared the coast, Odisha and West Bengal officials coordinated with the IMD and other meteorological agencies. This collaborative approach ensured the dissemination of timely information, essential for minimizing casualties and damages.
Cyclone Dana's Impact on Odisha
Heavy Rainfall and Flooding
In Odisha, Cyclone Dana brought torrential rainfall, particularly affecting coastal districts such as Puri, Kendrapara, and Jagatsinghpur. This heavy rainfall led to significant flooding in several low-lying areas, impacting both agricultural lands and residential areas. Paddy fields and other crops faced damage, raising concerns for local farmers and threatening food supply in the area.
The impact of these floods extended beyond the coast, with rivers swelling and breaching embankments. Infrastructure, including roads and bridges, faced severe strain, disrupting transportation and communication networks. Flooding in urban areas led to waterlogging, adding to the challenges faced by emergency response teams.
Wind Damage and Property Destruction

High-speed winds accompanied the heavy rainfall, with gusts reaching over 130 km/h in certain areas. These winds tore down trees, damaged power lines, and left many communities without electricity. In rural regions, houses with thatched roofs and structures made of lightweight materials were the most affected, with many homes completely destroyed. Urban areas were also impacted, with fallen trees and debris obstructing roads and damaging vehicles and buildings.
Evacuations and Relief Efforts
To ensure safety, the Odisha government proactively evacuated thousands of residents from high-risk areas. Shelter camps were set up, providing food, water, and medical assistance. Volunteers, NGOs, and local communities worked together to provide immediate relief, with resources such as dry rations, blankets, and essential medicines distributed across affected areas.
Cyclone Dana's Impact on West Bengal
Severe Storm Surges and Coastal Erosion
West Bengal’s coastal areas, including the districts of South 24 Parganas and East Midnapore, experienced powerful storm surges. These surges, combined with high tides, caused coastal erosion and inundated villages, particularly in the Sundarbans region. The storm surges not only threatened human settlements but also raised concerns about damage to the delicate mangrove ecosystem, which serves as a natural buffer against storm damage.
Impact on Kolkata and Urban Flooding
In Kolkata, Cyclone Dana caused urban flooding, with several areas submerged under knee-deep water. The city’s drainage system struggled to handle the heavy rainfall, leading to waterlogging in areas like North and South Kolkata. This disruption impacted transportation, business activities, and daily life, as people faced challenges commuting and accessing essential services. Efforts by the Kolkata Municipal Corporation included the deployment of water pumps and personnel to clear major roads.
Effects on Agriculture and Fishing
Cyclone Dana’s impact extended to West Bengal’s agriculture and fishing sectors. The storm destroyed vast tracts of paddy fields, and the salinization of farmland posed a long-term threat to productivity. Additionally, the fishing industry, a significant livelihood in coastal areas, was disrupted as fishermen were advised to stay ashore, impacting daily income and livelihoods.
Preparedness and Mitigation Measures
Government Preparedness Initiatives
Odisha and West Bengal have historically invested in disaster preparedness due to their vulnerability to cyclones. Before Cyclone Dana’s landfall, both state governments implemented proactive measures, including:
1. Evacuations: Authorities conducted mass evacuations in high-risk areas, moving people to temporary shelters and providing basic supplies.
2. Medical Preparedness: Health facilities were equipped to handle injuries, and stockpiles of essential medicines were readied for emergencies.
3. Public Awareness Campaigns: Awareness drives encouraged citizens to follow safety guidelines, ensuring they stayed informed about the cyclone’s trajectory and potential impacts.
4. Coordination with NGOs: Collaborations with NGOs and community organizations allowed for faster and more effective responses in rural and remote areas.
The Role of Technology and Real-Time Tracking
In recent years, technology has become a cornerstone of India’s disaster management strategies. For Cyclone Dana, satellite-based tracking systems and real-time meteorological data allowed for early detection and timely alerts. The Indian government used digital platforms to share cyclone updates, providing citizens with information through mobile applications and SMS alerts. These technologies ensured that even remote communities received timely warnings, giving people the opportunity to evacuate or take safety measures.
Climate Change and Cyclone Intensity
Cyclone Dana’s intensity and trajectory also draw attention to the increasing frequency and severity of cyclones in the Bay of Bengal. Climate change has been linked to warmer sea temperatures, which can fuel the development of stronger cyclonic storms. As sea levels rise, the impact of storm surges is also expected to increase, resulting in more extensive flooding and coastal erosion.
Building Resilience for the Future
The impacts of Cyclone Dana highlight the need for improved resilience strategies, particularly in vulnerable coastal regions. Steps that could strengthen future disaster management include:
1. Strengthening Infrastructure: Investing in more resilient infrastructure, such as cyclone shelters, reinforced embankments, and drainage systems, would mitigate damage.
2. Mangrove Restoration: Mangroves play a critical role in protecting coastlines from erosion and storm surges. Efforts to restore and expand mangrove cover could help reduce cyclone impacts.
3. Improving Early Warning Systems: Upgrading meteorological technology and ensuring effective communication channels could enhance the early warning systems’ reach.
4. Community Involvement: Training and involving local communities in disaster preparedness and response can strengthen resilience at the grassroots level.

Cyclone Dana serves as a reminder of the powerful impact that cyclones can have on India’s eastern states. Odisha and West Bengal demonstrated a proactive approach in preparing for Cyclone Dana, but the cyclone also highlighted vulnerabilities that need to be addressed in the face of a changing climate. By focusing on resilience-building, technological advancement, and community involvement, India can better protect its coastal populations from future cyclonic storms.
As climate-related challenges grow, the importance of a robust and comprehensive disaster management framework becomes clearer. Cyclone Dana is a testament to the need for preparedness and resilience in the face of nature’s unpredictability.
