With Northeast Monsoon expected to become active once again over Tamil Nadu Rains are likely to return over most parts of Coastal Tamil Nadu from today. Last night saw a few areas in Chennai receive spells of rains with some south suburbs around OMR receiving moderate rains early in the morning
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.
