Minimum temperatures too were above normal over Gujarat, Madhya Pradesh, peninsular India and Rajasthan.
Latest satellite images continued to present clear skies over most parts of peninsular India, indicating an anti-cyclonic circulation with high pressure, thus ruling out any clouding.
There are around 500 number of Rain Gauge stations available in Tamil Nadu which are maintained by WRO, TNEB and mostly by Revenue Departm...
