COLA model now suggests that the present circulation will become eleongated from North to South during next 2 days ..

And suggests a strong circulation will pop from this over S-S-E Bay on 1-Dec... this circulation is expected to track West from 2-Dec.

NOGAPS still maintains the same forecast for Bay.. now it shows as a Cyclone hitting central,N.Tamilnadu on 3/4-Dec.. http://ow.ly/i/1b1gQ 

Here's the COLA model for S-central Bay on 3-Dec.. a Depression .. http://ow.ly/i/1b1hx 

Today the strong circulation is over S.Andaman Islands .. http://ow.ly/i/1b1cT

And today the central Maharastra Anti-cyclone has slightly drifted W-S-W.. and now along N.Karnataka .. http://ow.ly/i/1b1cT

This Anti-cyclone is expected to move North into Madhyapradesh after 30-Nov... this will be good for upcoming S-E Bay LOW.

Central Maharastra Ant-cyclone is strong, sweeping dry winds from N-W India into N,W,central Bay .. http://ow.ly/i/1aOdI

IMD GFS expects the circulation over S-E Bay to move N-W into Bay and vanish over central Bay around 2-Dec.. http://ow.ly/i/1aOfI

But NOGAPS still persists with a D.Depression formation and movement towards Tamilnadu coast by 2-Dec.. http://ow.ly/i/1aOht
