Authorities on high alert
Heavy rainfall led to severe waterlogging in several districts across the state. The new bus stand in Tamil Nadu’s Viluppuram district, leaving passengers stranded and disrupting movement, PTI reported.
Heavy rainfall in Thoothukudi has also led to widespread waterlogging in the city. Local administrations have been instructed to stay on high alert, ensure relief camps are operational, and prepare for potential flooding and power outages.
The Tamil Nadu State Disaster Management Authority (TNSDMA) has reportedly deployed disaster response teams across coastal districts and intensified monsoon preparedness measures.
Officials have urged residents in low-lying and coastal areas to stay indoors, avoid unnecessary travel, and follow weather advisories closely as the deep depression continues to strengthen over the Bay of Bengal.
