CHENNAI: The Regional Meteorological Centre (RMC) on Monday issued an advisory warning fishermen to avoid venturing into the sea due to rough weather conditions ('Kallakkadal') along the coast of Tamil Nadu, Comorin area, and the Gulf of Mannar. Experts describe 'Kallakkadal' as a phenomenon where the normally calm sea suddenly turns turbulent without any prior indication, causing impact along the coast.
