THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.7N 83.9E,
IS NOW LOCATED NEAR 6.5N 82.0E, APPROXIMATELY 130 NM EAST OF
COLOMBO, SRI LANKA. ANIMATED ENHANCED WATER VAPOR IMAGERY SHOWS AND
A 082007Z AMSR-E MICROWAVE IMAGE DEPICTS DEEP CONVECTION DEVELOPING
OVER A BROAD REGION OF TURNING CONSOLIDATING INTO A LOW LEVEL
CIRCULATIONS CENTER (LLCC). UPPER LEVEL ANALYSIS INDICATES THE
REGION IS UNDER THE INFLUENCE OF LOW TO MODERATE VERTICAL WIND SHEAR
AND HAS GOOD POLEWARD OUTFLOW. SEA SURFACE TEMPERATURES IN THE AREA
ARE FAVORABLE FOR DEVELOPMENT AS WELL. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
FAIR

From afternoon of 9-Mar-09, We were hearing some heavy electric showers down south of Tamilnadu and thru Central coastal region of Tamilnadu.
And more heavy rains forecast for Delta region and Southern Tamilnadu. And some for Northern Tamilnadu as well.
Chennai:
It's cloudy and heavy from Morning. Temperature was mild thru the day. No Sunlight.
We had some mild sprinkles of rain.
We'll get some mild showers or strong drizzles late into the Night or early morning tomorrow (10-Mar-09).
Good signs for Rain are, Clouds are getting heavy by evening and wind is from East-south-east for most of the day.
Latest GFS says the system will intensify further and will cross the Delta regions of Tamilnadu.

And pressure maps show "Still a high pressure Anti-cyclone" circulation can be seen over the Northern Bay
AND
"Total percipitable water" over the Southern Bay region has increased dramatically.
This will favor more such LOW formations in coming weeks.
Latest BBC predictions say more rain for Delta region and some for us too.
