Cyclone Arnab poses risks of structural damage, uprooted trees, power outages, and flooding in low-lying areas. Heavy rainfall could disrupt transportation and daily life across multiple states. Coastal areas are particularly vulnerable to dangerous sea conditions, which could impact fishermen and maritime activities. The government has deployed National Disaster Response Force (NDRF) teams and kept rescue and relief teams from the Army, Navy, Air Force, and Coast Guard on standby.
