The IMD has flagged a low to moderate risk of flash floods in certain watersheds and neighbourhoods of Kerala and Tamil Nadu over the next 24 hours. Intense rainfall could overwhelm drainage systems, leading to rapid runoff and localised flooding. Coastal areas of Andhra Pradesh and other eastern regions may face strong winds and heavy rainfall as the system moves closer to the coast by October 28. Fishermen and coastal communities are particularly vulnerable due to squally winds of 50-60 kmph, gusting to 70 kmph, over the Bay of Bengal on October 25.
