48-Hour Coastal Alert: Sudden Ocean Flooding Risk for Kerala, South Tamil Nadu
What Happened
The Indian National Centre for Ocean Information Services (INCOIS) has issued a 48-hour swell surge warning for the coasts of Kerala, southern Tamil Nadu, and Lakshadweep. High-energy ocean swells originating nearly 10,000 km away in the southern Indian Ocean are expected to trigger sudden seawater ingress and flooding in low-lying coastal areas through August 20.
Key Takeaways
The threat is not from heavy rainfall but from powerful long-distance ocean swells, highlighting how weather events thousands of kilometres away can create dangerous coastal flooding along India's southwest coast.
