As flood water gushed out, onto the residential neighbourhoods and roads, houses were inundated and people were marooned.

At Krishnaberi in Tirunelveli, local people mobilised resources to rescue the stranded residents.
The huge volume of water flowing in waterfalls including Courtallam and Agasthiyar looked like multiple cloudbursts happening continuously.
Due to soil erosion, the ballast over which railway tracks were fixed firmly was washed away in Srivaikundam and iron tracks with only supporting cement slabs dangling precariously.
The water level rose above four feet in several locations of Thoothukudi and Tirunelveli and the bus termini in both the southern cities appeared like large swimming pools.

Vehicles parked near the bus terminus areas went under water.
Though there was a respite from rains in some areas, release of surplus water from dams continued, also contributing to water-logging.
