Cyclone Arnab has caused significant disruption in Andhra Pradesh and Odisha, with uprooted trees, power outages, and a storm surge of 1.5 to 2.5 metres inundating low-lying areas. Coastal districts in Odisha, including Kendrapara, Jagatsinghpur, and Puri, experienced heavy rain and strong winds. Inland flooding remains a risk as the storm moves further into Andhra Pradesh, Telangana, and Chhattisgarh. Rail services have been suspended along 53 routes, and schools in affected districts are closed. Despite the storm's intensity, no deaths have been reported, highlighting the effectiveness of pre-landfall evacuations.
