Cyclone Arnab is expected to cause significant disruption in coastal Andhra Pradesh, Telangana, Odisha, and Chhattisgarh. Extremely heavy rainfall and strong winds may lead to flooding, waterlogging, and damage to infrastructure, particularly in low-lying areas. A storm surge of 1 to 1.5 metres above the astronomical tide is anticipated along the Andhra Pradesh coast, posing risks of coastal inundation. Gale-force winds could damage homes, uproot trees, and disrupt power and communication lines. Residents in affected areas are advised to prepare for potential evacuations and follow official advisories.
