Cyclone Fenjal was a severe tropical cyclone that made landfall near Chennai, India on November 30, 2024. The cyclone brought heavy rainfall and strong winds, causing widespread damage and disruption to the city and surrounding areas. With sustained winds of up to 120 km/h (75 mph) and heavy rainfall exceeding 200 mm (7.9 in) in some areas, Cyclone Fenjal posed a significant threat to the region’s infrastructure, economy, and human life. As climate change intensifies, cities like Chennai must draw lessons from this experience. A key takeaway is the importance of bolstering water storage resilience in coastal cities.
Impact of Cyclone Fenjal on Chennai
Cyclone Fenjal brought heavy rainfall and strong winds to Chennai, resulting in widespread damage and disruption. The city’s water storage infrastructure was severely tested, highlighting the need for robust and adaptable systems to mitigate the impact of extreme weather events.
Key Lessons for Coastal Cities
The experience of Cyclone Fenjal in Chennai offers valuable insights for coastal cities:
Develop adaptive water storage infrastructure: Coastal cities must prioritize the development of water storage systems that can withstand extreme weather events. This includes designing and constructing water storage structures that can resist strong winds, flooding, and storm surges.
Implement integrated water management practices: Cities should adopt holistic water management approaches, incorporating water harvesting, conservation, and efficient use. This includes implementing measures such as rainwater harvesting, greywater reuse, and efficient irrigation systems.
Foster community engagement and participation: Cities must engage with local communities and involve them in the planning and management of water storage systems. This includes educating communities about the importance of water conservation, involving them in decision-making processes, and providing them with access to water storage infrastructure.
Establish early warning systems and emergency preparedness plans: Cities should develop robust early warning systems and emergency preparedness plans to ensure effective response to extreme weather events. This includes establishing emergency response teams, conducting regular drills and exercises, and providing emergency supplies and equipment.

Challenges and Opportunities
While Cyclone Fenjal highlighted the importance of water storage resilience in coastal cities, it also underscored the challenges and complexities involved in achieving this goal. Some of the key challenges include:
– Insufficient funding: Developing and maintaining robust water storage infrastructure requires significant investment, which can be a challenge for many coastal cities.
– Limited institutional capacity: Coastal cities often lack the institutional capacity and expertise to design, construct, and manage robust water storage systems.
– Climate change uncertainty: Climate change is introducing new uncertainties and complexities into water management, making it challenging for coastal cities to anticipate and prepare for extreme weather events.
Despite these challenges, Cyclone Fenjal also presents opportunities for coastal cities to enhance their water storage resilience. Some of the key opportunities include:
– Innovative technologies: New and innovative technologies, such as green infrastructure and smart water management systems, can help coastal cities enhance their water storage resilience.
– Collaboration and knowledge-sharing: Coastal cities can learn from each other’s experiences and share knowledge and best practices in water storage resilience.
– International cooperation and support: International organizations and donors can provide critical support and funding to help coastal cities enhance their water storage resilience.
Conclusion
The experience of Cyclone Fenjal in Chennai serves as a wake-up call for coastal cities to prioritize water storage resilience. By investing in adaptive water storage infrastructure, implementing integrated water management practices, fostering community engagement and participation, and establishing early warning systems and emergency preparedness plans, cities can reduce their vulnerability to extreme weather events and build a more resilient future.
