Cyclone Arnab prompted authorities to issue warning signal No. 2 at nine ports across Tamil Nadu and Puducherry on Monday, 26 October 2026, as the storm intensified over the Bay of Bengal and moved towards the Andhra Pradesh coast. Officials confirmed the measure, urging fishermen still at sea to return to shore immediately.
What Signal No. 2 Means
Signal No. 2 indicates that gale-force winds of 62 to 88 km/h are expected within 24 hours, posing a moderate threat to life and property. The warning level is a step above routine advisories and activates specific precautionary measures at affected ports. Fishing communities along the coastline have been alerted to the rapidly changing conditions offshore.
Ports Under Warning
The nine ports placed under the warning span both the state and the Union Territory. In Tamil Nadu, the affected ports are Chennai, Ennore, Kattupalli, Cuddalore, Nagapattinam, Pamban, and Thoothukudi. In Puducherry, the ports of Puducherry and Karaikal are also under the alert.
Storm's Track and Expected Intensification
Cyclone Arnab originated as a low-pressure area over the Bay of Bengal and intensified through successive stages before being classified as a cyclonic storm on Monday. As of the latest advisory, the system was positioned over the east-central Bay of Bengal and adjoining west-central waters. According to officials, the storm is expected to move northwestwards and strengthen into a severe cyclonic storm by Tuesday, before crossing the Andhra Pradesh coast. The precise timing and location of landfall had not been specified in available forecasts.
Tamil Nadu Rainfall Situation
Notably, available forecasts do not indicate rainfall directly linked to Cyclone Arnab for Tamil Nadu. Officials clarified that rain already experienced in the state is described as unrelated to this weather system. The distinction is significant given public concern over simultaneous rain and the developing storm. Port warnings along Tamil Nadu's coastline and Puducherry relate specifically to deteriorating sea conditions, and should not be conflated with expectations of cyclone-driven rainfall over land, officials said.
Precautions and What Comes Next
The immediate priority for authorities remains ensuring that fishermen at sea return to shore before conditions worsen further. Coastal communities in both Tamil Nadu and Puducherry have been briefed. The storm's continued northwestward movement and any further intensification will determine the precise areas affected along the Andhra Pradesh coast. Authorities are expected to revise advisories as the system progresses closer to landfall.
Point of View
Such distinctions have created public confusion and delayed precautionary action. Authorities would do well to communicate the dual narrative — sea-state warnings versus land rainfall — with maximum clarity, especially for fishing communities who must make real-time decisions. With intensification to severe cyclonic storm status expected by Tuesday, the advisory window is narrowing fast.
