THANE IS AT 81E,11.8N ABOUT 100KM SOUTH EAST OF CHENNAI
Rainfall associated with it already began in Chennai late yesterday with moderate winds!
As seen from the above IR-NHC spectrum imagery, it appears that the LLCC ( Low Level Cyclonic Circulation Center) is rapidly approaching towards the area between Puducherry and Cuddalore!
The image on the right hand side is of the Doppler Radar Chennai of 1335UT i.e 0635PM IST which clearly shows the LLCC ( Noted as circular vortex South East of Chennai in the circle of Radius 100km!) is approaching Puducherry for a head on. The radar estimates that the landfall shall be sometime tomorrow ( 30th Dec 2011) morning around 0530hrs IST
Cyclone Thane has been a Cat 1 Cyclone during the landfall which was a bit expected as it didn't had that much space where it could get weak. It shall now start weakening as it is losing the Sea surface contact.

RIGHT-
This is a classical example of Doppler Effect with a Tropical Cyclones in Northern Hemisphere.
A cyclone due to coriolis force of earth's rotation rotates ANTICLOCKWISE in Northern Hemisphere. Thus the winds in the Northern half of center are anticlockwise i.e during such landfall from East the winds move towards the land( DENOTED BY BLUE COLOR IN THE IMAGE) and in the Southern Half ( RED COLOR) means winds are moving away!
Thus PEOPLE ARE BEING INFORMED TO STAY AWAY FROM DAMAGES ESP FROM HIGH WINDS,RAINS AND STORM SURGES
