India's eastern coastline is bracing for another potential cyclone just days after Cyclone Arnab made landfall, raising critical questions about the region's capacity to manage back-to-back weather disasters. During the landfall of Cyclone Arnab on the night of August 27-28, authorities successfully evacuated over 180,000 people across Andhra Pradesh and Odisha, supported by satellite tracking from ISRO and coordinated efforts by disaster response units.
While India has spent over a decade developing a robust network of Doppler Weather Radars (DWRs), evacuation shelters, and early-warning systems, the rapid succession of storms presents a unique challenge. The India Meteorological Department (IMD) currently operates or integrates data from eight radar locations along the coast, including Chennai, Kolkata, Visakhapatnam, and Paradip. Despite this, the government acknowledges persistent gaps in radar coverage, particularly in hilly and island regions, and has proposed further expansion.
Andhra Pradesh has implemented a Cyclone Information Management System to map vulnerable populations and critical infrastructure. During Cyclone Arnab, the state deployed nearly 1,100 medical teams and opened over 2,000 shelters. However, officials noted that some local administrative units have yet to provide complete readiness data, complicating the assessment of total preparedness. Meanwhile, Odisha continues to rely on its Early Warning Dissemination System, which utilizes 122 alert towers to reach coastal communities even when conventional communication networks fail.
In Tamil Nadu, the focus remains on urban resilience. The Greater Chennai Corporation has been working to mitigate waterlogging through expanded stormwater drainage networks and the pre-positioning of pumps, though officials recognize that drainage infrastructure alone cannot fully withstand the intensity of cyclone-driven storm surges.
Much of this infrastructure was bolstered by the National Cyclone Risk Mitigation Project (NCRMP), which saw a combined expenditure of over Rs 4,300 crore across two phases ending in 2023. These investments funded multipurpose shelters, saline embankments, and underground electrical cabling.
Experts warn that the primary concern is not just the frequency of storms, but the rising heat content in the Bay of Bengal, which can fuel rapid intensification. As climate change alters weather patterns, the challenge for India's east coast has shifted from simple detection to the logistical strain of recovery. The ability to restore power, clear roads, and replenish medical supplies between storms remains the ultimate test of the region's disaster management framework.
