"07B" - Tracking west-north-west

Yesterday night it seemed like 07B is going to dissipate in open waters.
Now (8:55 AM) the satellite pic shows a huge cloud mass has gathered around it's center. Still 07B is no way a Cyclone, just a Depression in the making.
Here is latest satellite pic ...

Take a look at this BBC- rainfall forecast for Sunday, surprisingly it shows heavy rainfall around North-Tamilnadu. And according to JTWC tracking, 07B will make a initial landfall around north-east srilanka and then crash into Tamilnadu.

  3. Excuse me, BBC forecast was way off target during Nisha.

    According to BBC, Nisha was suppose to strike Chennai, then they changed and went southward. I still think GFS model is most accurate. In almost every newspaper in Chennai it says it will rain sunday thru tuesday. For once I have been downplaying this forecast saying its wrong. I hope I am not wrong, otherwise people will have a fool out of me
