Intense rainfall lashed Chennai, neighbouring northern districts, and several coastal belts across Tamil Nadu on Friday under the active influence of the Northeast Monsoon. The Regional Meteorological Centre (RMC) has issued weather alerts as atmospheric conditions over the central and southwest Bay of Bengal indicate the development of an active low-pressure area over the next 24 to 48 hours.

Morning showers across Chennai led to localized water stagnation along several interior stretches and slowed early vehicular traffic on key arterial corridors. Widespread precipitation has also been reported from Chengalpattu, Kanchipuram, Tiruvallur, Cuddalore, Villupuram, and districts across the Cauvery delta region including Nagapattinam and Mayiladuthurai.

Bay of Bengal Low Pressure: What the Weather Report Indicates

Meteorological observations show a cyclonic circulation active over the southwest Bay of Bengal, which is likely to trigger heavy to very heavy rainfall spells across northern coastal districts of Tamil Nadu and Puducherry. Weather officials clarified that while social media speculation points toward a severe cyclone, current atmospheric conditions primarily forecast heavy continuous rainbands and gusty coastal winds reaching 35 to 45 km/h rather than an immediate super cyclonic storm.

Civic Measures and Disaster Preparedness in Chennai

The Greater Chennai Corporation (GCC) and district administrative authorities have deployed emergency field squads and equipment to manage excess surface runoff:

• Pump Operations: High-capacity dewatering pumps have been stationed at subways, underpasses, and vulnerable waterlogging hotspots.
• Reservoir Levels: Officials are tracking inflow rates at Poondi, Chembarambakkam, Puzhal, and Cholavaram reservoirs to ensure regulated discharge of surplus water.
• Fishermen Warning: Coastal fishers have been advised against venturing into deep-sea areas off the southwest Bay of Bengal and the Gulf of Mannar until surface sea conditions normalize.
• Control Rooms: Civic helplines and 24x7 control rooms remain active across all city zones to address water stagnation complaints and fallen tree clearance.

Advisory for Residents and Commuters

Commuters are advised to exercise caution, maintain safe vehicle speeds on wet roads, and monitor local municipal traffic updates before planning daily transit. Citizens living in low-lying areas are encouraged to track verified alerts from the meteorological department and keep essential emergency kits ready in case of prolonged regional power cuts or thunderstorm warnings.
