Cyclone Arnab poses a significant threat to India's eastern coastline, particularly the state of Andhra Pradesh. The storm is expected to bring destructive winds with speeds of 115-125 km/h (71-78 mph) and gusts up to 140 km/h (87 mph) at landfall. Heavy rainfall is anticipated, which could lead to flooding in low-lying areas and disrupt transportation. Coastal regions may experience dangerous sea conditions, with the potential for damage to infrastructure, power outages, and uprooted trees. Communities in the projected path are advised to prepare for severe weather impacts.
