The immediate threat of Cyclone to North-Tamilnadu coast has been lowered.
Take a look at the latest GFS for 7-Dec-08.
Moreover going by latest satellite pic, there is also no visual of significant Cloud formations over south-east Bay.
Still we can see clouds hanging over south-east Bay...
A LOW pressure system might hit northern Srilanka and some parts of Southern Tamilnadu around 7th or 8th of December.
Keep your fingers crossed. Wait & watch for another 48hrs.
