After sizzling for the past few days under the early summer sun, it looks like there might be some respite ahead for the people of Tamil Nadu. The latest bulletin issued by the Regional Meteorological Centre predicts a thunderstorm with light rain at isolated places in Tamil Nadu. The trend, brought on by the early sea breeze, is likely to continue until April 7, Wednesday. Parts of Chennai saw a sudden drop in temperature on Sunday morning brought on by grey-clouded skies. Weather blogger Pradeep John attributes this to the fizzling out of the depression that had formed near Myanmar. “Look who is coming back. The Depression near Burma, which was one of the reasons we had a heatwave, fizzles out. The pulse from Depression comes back as dud UAC to TN. This brings back the easterlies and also thereby resulting in a drop in temperature,” he tweeted. Look who is coming back.
