N. Puviarasan, director, Area Cyclone Warning Centre, Chennai, said the weather system is likely to develop into a low pressure area, and move in a northwesterly direction by Wednesday or Thursday. It may not bring much rain to Tamil Nadu, but after a slight lull, thunderstorm activity may resume later in the week due to convective activity.
Widespread thundershowers ensured an overcast sky over Chennai. The maximum temperature in Nungambakkam and Meenambakkam dropped by one degree Celsius, and both weather stations recorded around 33 degree Celsius on Tuesday. The same weather trend may continue, and there are chances of light rain in some areas till Thursday, officials said.
