IMD said: "Yesterday’s north-south trough from the cyclonic circulation over Madhya Maharashtra & neighbourhood to Comorin area across Karnataka & Tamil Nadu at 0.9 km above mean sea level has become less marked."

The ongoing showers is likely to result in waterlogging in some areas, making roads slippery and affecting traffic movement in parts of Chennai and surrounding regions. The commuters have been advised to exercise caution while traveling.

With the potential for thunderstorms and heavy showers, residents are advised to stay updated on weather alerts and take necessary precautions.
