Trough of Low in Bay Update: The Trough of Low in Bay continues its struggles to consolidate. With a very feeble Low Level Circulation seen over Southeast Bay & adjoining Southwest Bay. It appears going by the current conditions this Trough of Low could continue its life as weak disturbance. In a separate development we could possibly see a different pulse evolve closer to Andaman and possibly become the dominant vortex in this Trough though this needs to be monitored to see if it could happen.
Considering the situation is fairly fluid at the moment we feel it would be prudent to stick to short term estimates.
Parts of Coastal TN could receive isolated spells of rains today. Areas around North Coastal TN could start to receive rains around 11 AM with one or two places getting heavy spells in and around Chennai.
