Some parts of Tamil Nadu are likely to continue to be in the grip of searing heat. The Meteorological Department has forecast heatwave-like conditions in isolated pockets of the State as mercury level may soar about 2-4 degrees Celsius above normal on Sunday.

Various interior districts are already sizzling as day temperature has peaked above 40 degrees Celsius for two or three days now. They include places such as Erode, Vellore, Salem and Karur. On Saturday, the maximum temperature almost touched 40 degrees Celsius in districts such as Salem, Tirupattur and Madurai.

The maximum temperature in Chennai too has been steadily on the rise. The weather stations in Nungambakkam and Meenambakkam have registered nearly 35.7 degrees Celsius and 37.7 degrees Celsius respectively.

P. Senthamarai Kannan, Director, Area Cyclone Warning Centre, Chennai, says prolonged dry weather, light winds and lack of cloud cover have retained the heat in parts of the State. Clear sky has maintained a minimum temperature of 25-26 degrees Celsius in most parts of Tamil Nadu instead of the usual 28-29 degrees Celsius, and this has reverse impact during the day.

Monitor heat wave

“We cannot declare it as heatwave condition in the State as weather is yet to meet the criteria. The mercury level has to soar 4.5 degrees Celsius above the day’s average temperature in two weather stations for a minimum of two days,” he said. Though the day temperature has crossed 40 degrees Celsius in some interior districts, it has remained 3-3.5 degrees Celsius above normal as of now.

The weather will be monitored for heat wave conditions. The wind flow pattern may change in a few days, Mr. Kannan added. Dry weather will prevail till April 19. The Meteorological Department has forecast that day temperature will hover around 37-38 degrees Celsius till Monday.
