All thanks to the couple of Monsoon systems that are affecting the weather over Chennai. According to Skymet Weather, the low pressure area over north coastal Andhra Pradesh continues to persist.
In addition to this, wind discontinuity is also seen over Tamil Nadu. All the systems combined together will bring moderate showers over Chennai during the next 48 hours.
