The northeast monsoon arrived in Tamil Nadu on October 29 as parts of the State received heavy rainfall accompanied by thunderstorms leading to waterlogging in several parts of the State. Chennai received the heaviest rainfall in a day in October since 2014 and several areas were flooded. According to the Tamil Nadu Metrological Department, Chennai will most likely continue to receive heavy rain over the next few days. R Pradeep John, who runs The Tamil Nadu Weatherman, a popular blog covering the weather, posted ‘Very active phase of monsoon, yet to begin, and when MJO comes in, we are in for a treat. Yesterday massive rains was just a bonus’ on his Facebook page recently.
Three days of continuous heavy rainfall led to massive floods that killed several people in Telangana, Andhra Pradesh and Maharastra earlier this month. This was caused by a weather that formed in the Bay of Bengal, hitting the east coast and moving westward, weakening on the way.
