There is a chance for thunderstorm activity in interior districts this week. One or two places could experience heavy rain. The Meteorological Department has also limited the heat wave warning to a few places in the interior areas for the next few days.
Though there was cloud cover over the city and expectation of thundershowers, a few places on Chennai’s outskirts experienced thunderstorms on Tuesday. As several places continued to sizzle with mercury level climbing a few notches above normal, some interior areas received rain. The maximum temperature peaked above 40-degree Celsius in places including Palayamkottai, Thanjavur, Vellore, Karur, Tiruchi and Madurai.
Chennai too experienced sweltering weather as the mercury level rose to 40.1 degree Celsius in Nungambakkam and 42 degree Celsius in Meenambakkam on Tuesday.
N. Puviarasan, director, Area Cyclone Warning Centre, said, “We have withdrawn heat wave warning for many places as easterlies are becoming stronger. The departure from normal temperature has come down to 3 degree Celsius in several places. This would also mean possibility of thunderstorms due to convective activity and bring down day temperature in interior districts.”
During the past 24 hours ending at 8.30 a.m., Tiruppur and Manjalar in Theni district recorded 5 cm and 4 cm of rainfall. On Tiruttani remaining one of the hottest places in the State this year, he said it is of rocky terrain and away from the coast. Moreover, it borders Andhra Pradesh where north and northwesterly winds are dominant. So, the temperature level shoots up fast.
“We can expect a dip in the temperature in the coming days. In Chennai, the time of onset of sea breeze determines the day temperature,” he added.
