Reportedly as the northeast monsoon finally set in over Tamilnadu on Wednesday, Chennai will receive rains from October 20. Meanwhile the city experienced continuous rainfall on Thursday morning, becoming the wettest northeast monsoon day in Chennai since November 2017. Furthermore according to the Regional Meteorological Centre in Chennai, light to moderate rain is likely to occur at many places over Tamilnadu between Friday and Monday and heavy rain is likely to occur at isolated places over the state.
Further as far as Chennai is concerned, the weather agency predicts that the sky condition is likely to be generally cloudy. It states for Friday and Saturday “Light to moderate rain or thundershowers is likely to occur. Maximum and minimum temperatures are likely to be around 28 and 25 degree Celsius respectively”. Reports added the Nungambakkam weather observatory recorded 30 mm of rainfall while Meenambakkam recorded 52.6 mm in Chennai. A cyclonic circulation over the southwest Bay of Bengal is likely to induce a low pressure area near south Tamilnadu.
Moreover traffic signals in parts of the city were affected due to the rains. As per report this resulted in traffic snarls on Thursday, following which the Greater Chennai Traffic Police regulated traffic. Perhaps city based weather blogger pradeep John, who runs the popular Facebook page Tamilnadu Weatherman has predicted night and morning rains for this season.
