Moderate rain expected to push into #Chennai, N-coast Tamilnadu and along S-coast Andhra in next 7/8 hrs.

90A - Slowly taking shape and intensifying !

Latest analysis show a intensification to "almost" a Depression now, but the present pressure is around 1003mb.
Presently located at 11.7 N , 60.9 E.

Most models predict a intensification to a Cyclone in next 48hrs and slowly drift W-N-W or N-W.
Either the COAMPS model or the HWRF model can become true !!
COAMPS suggests a Cyclone and track W-N-W towards Yemen coast during next 3/4 days !
HWRF predicts a N-W movement, intensify to Cyclone and reach up to S Oman coast around 29/30-Oct.

NEM is to set in

http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/fw/grad.rxml  [What is gradient wind?]

 The Gradient wind analysis is the indicator of what is observed about the prevailing wind in the southern parts of India, especially in TN and Kerala

The WML in AS is expected to become depression and then to cyclone , because of the feeder from strong wind system. Still the influence of SWM over North Indian Ocean around India is valid.

NEM is still to put a foot in TN
