This is the latest satellite pic... it seems the system has gained strength and moved north. Now it's almost parallel to Chennai and expected movement is north,...presently it's moving north.
Take a look at the latest bulletin from US Navy,
----------------
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.3N 89.8E,
IS NOW LOCATED NEAR 8.0N 89.8E, APPROXIMATELY 595 NM EAST OF COLOMBO,
SRI LANKA. RECENT METSAT IMAGERY SHOWS AN AREA OF IMPROVED PERSISTENT
DEEP CONVECTION AND CONTINUED POLEWARD DIFFLUENCE. A PARTIAL 281457Z
ASCAT IMAGE SHOWS A BROAD, BUT BETTER ORGANIZED LOW LEVEL CIRCULATION
CENTER (LLCC) WITH 20 TO 25 KNOT UNFLAGGED WINDS AT THE CENTER AND
WESTERLY FLOW TO THE SOUTH. THE SYSTEM CURRENTLY LIES UNDER AN AREA
OF LOW TO MODERATE SOUTHEASTERLY VERTICAL WIND SHEAR, BUT VERTICAL
SHEAR IS FORECAST TO DECREASE THROUGH THE NEXT 24 HOURS AS THE SYSTEM
TRACKS BENEATH THE SUBTROPICAL RIDGE AXIS. FAVORABLE UPPER LEVEL
DIFFLUENCE CONTINUES TO HELP FUEL THE CONVECTION. DUE TO THE IMPROVED
ORGANIZATION OF THE LLCC, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED
TO FAIR.
