South West Monsoon has been slowly extending its arms and making its presence felt over North and northwest parts of India. On the other hand monsoon is likely to turn active along most parts of west coast and Ghat areas.
Parts of North Tamil Nadu districts like Tiruvallur, Kanchipuram, Cuddalore, and nearby districts like Vellore, Villipuram, Tiruvannamalai which are close to coastal areas would see scattered rainfall in the evening associated with thunderstorms. Chennai too could see isolated showers towards the evening.
