Cyclone Arnab has completed its landfall process in India's Andhra Pradesh, transitioning from a very severe cyclonic storm to a severe cyclonic storm as it moved entirely over land, according to the India Meteorological Department (IMD). Authorities had evacuated approximately 180,000 people ahead of the storm's arrival, with Chief Minister Naidu stating that no loss of life had been reported in the state following the event.

In preparation for the cyclone, the state government had placed Andhra Pradesh on high alert, intensifying disaster preparedness measures. Heavy to extremely heavy rainfall was forecast for 13 districts on October 28 and 29. As part of these efforts, 4,711 pregnant women were moved to health facilities, and 15 teams from the National Disaster Response Force (NDRF) and State Disaster Response Force (SDRF) were deployed. The Roads and Buildings (R&B) department also established emergency teams to maintain road safety and ensure prompt restoration of traffic flow.

Further social mobilisation saw schools in 16 coastal districts closed, with 609 of these institutions repurposed as relief shelters. Over 17,000 volunteers from organisations including the National Cadet Corps (NCC), National Service Scheme (NSS), and Scouts were mobilised to assist with response efforts.

The cyclonic weather system led to disruptions in air travel and train schedules across the region. Neighbouring Telangana also experienced meteorological effects, with temperatures dropping by up to 2.5°C in some areas due to the storm's influence.
