La Niña's development in the Pacific and the Madden-Julian Oscillation (MJO) in the Arabian Sea are causing a swell surge. Coastal flooding is predicted for Kerala and Tamil Nadu until January 15, 5:30 PM. Waves up to 1 meter high pose a risk of sea incursion. Fishermen and coastal residents are urged to exercise caution and heed warnings due to potential sea erosion and heavy rainfall.
