Chennai Rains Subside, BoB Depression Crosses TN-Andhra Coast; Bengaluru To Get More Showers

Southern states have been reeling under heavy rains for the past few days, with Tamil Nadu's Chennai and Karnataka's Bengaluru being among the worst-hit cities along with several other areas. The intense rain in parts of south India, particularly Tamil Nadu, is due to the northeast Monsoon that set in on Tuesday and was intensified due to a well marked low pressure area over Bay of Bengal that turned into a depression in the evening that day and was expected to cross coast near Chennai on October 17 morning, as per the India Meteorological Department (IMD).

Rains subsided on Wednesday in Tamil Nadu, a day after intermittent, widespread rains lashed Chennai and other parts of the state, bringing residential neighbourhoods and roads under knee-deep water and leading to traffic congestion besides affecting public transport services.

The Tamil Nadu government had announced closure of government schools, colleges and offices for October 16 in Tiruvallur, Kancheepuram, Chengalpattu and Chennai districts.
