A bus driver died after heavy rainfall triggered multiple mudslides in the Nilgiris, burying a government bus travelling from Coonoor to Mettupalayam on the intervening night of October 23 and 24.
The India Meteorological Department forecast heavy to very heavy rainfall across several Tamil Nadu districts over the next three days, alongside a cyclonic storm likely to form over the west-central Bay of Bengal on October 26.
Authorities closed tourist spots, suspended mountain train services, and shut schools in the Nilgiris, while flash floods washed away a temporary causeway in Krishnagiri district.
