290300Z POSITION NEAR 11.9N 82.3E. TROPICAL CYCLONE (TC) 06B (THANE), LOCATED APPROXIMATELY 160 NM EAST- SOUTHEAST OF CHENNAI, INDIA, HAS TRACKED WESTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON RADAR IMAGERY FROM CHENNAI, INDIA, A RECENT SATELLITE FIX FROM PGTW, AND A 282221Z SSMI IMAGE. THE INTENSITY ESTIMATE OF 75 KNOTS IS CONSISTENT WITH DVORAK T-NUMBER VALUES FROM THREE REPORTING AGENCIES RANGING FROM 65 TO 77 KNOTS. THE DEEPEST CONVECTION REMAINS ALONG THE WESTERN AND SOUTHERN PERIPHERIES OF WELL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) EVIDENT IN THE 282212Z SSMI IMAGE. RADAR REFLECTIVITY DATA SHOWS A SYMMETRIC LOW TO MID-LEVEL EYE FEATURE APPROXIMATELY 40 NM IN DIAMETER. TC 06B CONTINUES TO TRACK WESTWARD UNDER THE STEERING INFLUENCE OF A SUBTROPICAL RIDGE (STR) POSITIONED TO THE NORTH OF THE CYCLONE AND SHOULD CONTINUE TRACKING WESTWARD UNTIL MAKING LANDFALL JUST PRIOR TO TAU 24. THE CYCLONE LIES TO THE WEST OF AN UPPER-LEVEL ANTICYCLONE. THE UPPER-LEVEL ENVIRONMENT IS MARGINAL, WITH FAVORABLE BUT DECREASING RADIAL OUTFLOW AND INCREASING VERTICAL WIND SHEAR. THE CYCLONE IS ALSO MOVING OVER WATERS WITH LOWER HEAT CONTENT THAT SHOULD, ALONG WITH INCREASING VERTICAL WIND SHEAR AND DECREASING OUTFLOW, INDUCE SOME WEAKENING PRIOR TO LANDFALL. AFTER LANDFALL, INTERACTION WITH ROUGH TERRAIN WELL INLAND FROM THE RELATIVELY FLAT COASTAL AREA WILL LEAD TO STEADY DISSIPATION. ASIDE FROM THE WEBER BAROTROPIC MODEL, WHICH TRACKS THE CYCLONE POLEWARD INTO THE STEERING RIDGE, AND THE UK MET OFFICE MODEL, WHICH HOLDS THE SYSTEM TOO WEAK IN BOTH THE ANALYSIS AND FORECAST AND DEPICTS AN ERRONEOUS SOUTHWESTWARD TRACK WITH THE LOW-LEVEL FLOW, THE NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT WITH THE CURRENT FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290000Z IS 22 FEET.
IMD warning, 7:30am

Very Severe Cyclonic Storm THANE over southwest Bay of Bengal:-Cyclone Warning for north Tamilnadu and south Andhra Pradesh coast : Orange Message
The very severe cyclonic storm THANE over southwest Bay of Bengal moved west-southwestward and lay centered at 0530 hrs IST of today, the 29th December 2011 near latitude 12.30N and longitude 83.00E, about 300 km east-southeast of Chennai (Tamilnadu) and 480 km north-northeast of Trincomalee (Sri Lanka). The system is likely to move westwards and cross north Tamil Nadu coast between Nagapattinam and Chennai, close to Puducherry around morning of 30th December 2011. However, as the cyclonic storm will come further close to coast, there is probability of slight weakening before landfall.
My daughter Liz and her cousin Janine were staying on the beach at Waves during the cyclone. They luckily escaped in the dark through the wind and waves. Liz lost her underwater camera. It would be interesting to see the pictures on the memory card if it is ever found. Very grateful to the people who helped them.
