Coastal thoroughfares across north Chennai and Tiruvallur district witnessed sudden marine inundation and high waves on Tuesday evening, October 27, 2026, as Very Severe Cyclonic Storm Arnab churned through the western Bay of Bengal toward Andhra Pradesh.
Tidal waters spilled onto the Ennore Expressway and adjacent roadways, prompting residents in Kasikoilkuppam, Ennore, Tiruvottiyur, Bharathi Nagar, and Ramakrishna Nagar to vacate ground-level areas in alarm. Local civic authorities and Tiruvottiyur MLA N. Senthil Kumar visited vulnerable shoreline pockets, urging the public to avoid panic while monitoring teams tracked sea-level changes. Weather officials expect calmer marine conditions along the northern Tamil Nadu coastline by noon on October 28.
According to updates from The Hindu, the center of Cyclone Arnab lay approximately 140 kilometers from Kakinada and 170 kilometers from Visakhapatnam as of 2:30 p.m. Tuesday. The India Meteorological Department (IMD) projects the system to make landfall just south of Yanam by Wednesday forenoon, bringing sustained wind speeds of 125 to 135 kmph with gusts reaching 150 kmph.
Multi-State Evacuations and Operational Halts
Emergency services across Andhra Pradesh and Odisha initiated extensive disaster-mitigation protocols ahead of landfall. In Andhra Pradesh, nearly 89,000 residents across vulnerable belts in the Kakinada district are being shifted to 101 designated relief camps. Maritime port authorities hoisted the highest danger signal at Kakinada Port as seawater breached coastal defenses in Uppada.
In neighboring Odisha, disaster management authorities initiated procedures to evacuate roughly 48,000 residents living along prone shorelines. Local resistance in vulnerable deltas prompted stepped-up enforcement, with Yanam Regional Administrator Shivraj Meena noting, "Most of them are not willing to move to the relief camps, forcing us to deploy NDRF personnel and local police to persuade them."
Transport networks faced heavy shutdowns across the eastern corridor. Rail operators cancelled at least 72 train services operating through coastal Andhra Pradesh, while flight operations at Visakhapatnam airport were either diverted or cancelled. Coastal leisure areas and public beaches in Visakhapatnam were ordered closed after parts of the city logged over 100 millimeters of rain in a single day.
