Chennai rain: NDRF teams deployed, schools shut in 4 districts | 10 points – Hindustan Times

Chennai is still recovering from the heavy pounding it received by the rainfall, which started on Saturday. The continuous downpour for 24 hours led to inundation of most areas on Sunday and opening up of sluice gates of three city reservoirs to let out surplus water.

This is the heaviest rainfall on record since 2015 and has been caused by the northeast monsoon, which has been impacted by continued La Nina, a complex weather pattern caused by variations in ocean temperatures in the equatorial band of the Pacific Ocean. News agency PTI quoted Tamil Nadu’s revenue and disaster management minister KKSSR Ramachandran as saying that four people have died in rain related incidents and one person has been injured.
