Tamil Nadu is likely to experience heavy rainfall in its northern districts, the Indian Meteorological Department has said.
Speaking to media persons in Chennai on Friday, S Balachandran, Director, Area Cyclone Warning Centre, Chennai, said, “Over the next 24 hours, there will be moderate rainfall in Tamil Nadu and Puducherry. In northern districts of Tamil Nadu, there is a chance of heavy rainfall. Chennai and suburban areas will continue to be cloudy and experience moderate rainfall.”
According to a report in The Hindu, coastal districts of Tamil Nadu- Chennai, Cuddalore and Nagapattinam- may experience a change in weather from warm to cool. "An upper air trough in easterlies that continues to persist will bring scattered rainfall over north Tamil Nadu," says the newspaper.
As per a Times of India report, Chennai experienced a total of 4 cm of rainfall as of 8 am on Friday while Chidambaram and Villupuram received 9 cm of rainfall. As of August 29, Tamil Nadu has received a total of 170.2 mm of rainfall.
Balachandran also reportedly said that despite the weather system moving westwards, scattered rains would continue in the state.
The Director attributed the rains to the south-west monsoon which is still active in parts of Tamil Nadu and Puducherry.
The Hindu report quotes officials as saying that weather models have suggested 60-70% chances of El Nino. The El Nino is a warm ocean current of variable intensity that develops in the central and east-central equatorial Pacific, sometimes causing drastic weather conditions in other parts of the world.
“The State has recorded either normal or above normal rainfall in 15 years. However, El Nino is not the only determining factor for the monsoon,” the Director said.
