Lets see the synoptic situation and the wind direction. The Depression in Bay will move up north caught by the westerly trough and will got West Bengal / Bangladesh Coast. So the Westerly trough dipping from North dragged the Depression away from Andhra to West Bengal / Bangladesh.
What a perfect with dry northerlies meeting with westerlies. This will create very intense thunderstorms. To be honest very excited to see how these thunderstorms will form and look like, these interacting patterns are rare ones and dump good rains.
October 22-24 Rainfall places (significant ones)
North Tamil Nadu
Krishnagiri, Erode, Dharmapuri, Tirupattur, Tiruvannamalai, Salem, Vellore, Tiruvallur, Ranipet, Kancheepuram, Villupuram, Chengalpet, Chennai. Chennai – What a Blazing Sun we are having at Chennai right now, let it be, we need this blazing sun for rains later at evening / night.
