The week leading up to New Year is likely to be pleasant for Chennai residents. The latest bulletin from Regional Meteorological Centre predicts cloudy skies and light showers in some areas of the city for the next 48 hours.

According to a report in The Times of India, light rain in the coastal districts of the state is expected around the first week of January. This is due to the extension of the Northeast Monsoon into January, N Puviarasan, director of Area Cyclone Warning Centre at RMC, Chennai said. Popular weather blogger Pradeep John, who runs Tamil Nadu Weatherman on Facebook, said, “Hopefully, there is some light rains expected around new year for KTC (Kancheepuram, Tiruvallur, Chennai) and there is also some rains in 1st week of January.”

According to RMC’s bulletin, light to moderate rain is likely to occur at isolated places over Tamil Nadu and Puducherry until December 29.
