Chennai: The city and several other districts in this country tend to receive more rain in the coming days due to advantageous weather conditions and the possibility of withdrawal of Southwest Monsun from October 6.
Monsun withdrawals will open the way for the emergence of the northeast road of Monsun, which brings more than 60% of the city’s annual rainfall.
