JTWC warning and projected path, 2:30am
--------------------------------------------------------------
272100Z POSITION NEAR 12.5N 85.9E.
TROPICAL CYCLONE (TC) 06B (THANE), LOCATED APPROXIMATELY 350 NM EAST 
OF CHENNAI, INDIA, HAS TRACKED WEST-NORTHWESTWARD AT 04 KNOTS OVER 
THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS 
CONVECTION DEEPENING AND CONSOLIDATING AROUND A BROAD LOW-LEVEL 
CIRCULATION CENTER (LLCC). A 271419Z 37 GHZ SSMIS IMAGE REVEALS A 
CONCENTRIC AND WELL-ORGANIZED LLCC, WITH THE MAJORITY OF DEEP 
CONVECTION OCCURRING OVER THE SOUTHWESTERN QUADRANT. TOTAL 
PRECIPITABLE WATER LOOPS INDICATE THE DEEP MOISTURE ASSOCIATED WITH 
THE SYSTEM IS SEPARATING FROM VIGOROUS WESTERLIES ON THE EQUATORIAL 
SIDE, WHICH MAY LIMIT FURTHER INTENSIFICATION. ANIMATED WATER VAPOR 
IMAGERY REVEALS THAT THE WEAKENING EFFECTS OF SHEAR ARE BEING 
COMPENSATED BY VIGOROUS POLEWARD OUTFLOW. THE CURRENT INTENSITY IS 
BASED ON A COMBINATION OF A DVORAK ASSESSMENT OF 55 KNOTS FROM PGTW 
AND THE MICROWAVE SIGNATURE. TC 06B IS UNDERNEATH THE SUBTROPICAL 
RIDGE IN A REGION OF HIGHLY DIFFLUENT FLOW, WITH VERTICAL WIND SHEAR 
ESTIMATED AT 15 KNOTS. ALONG-TRACK SEA SURFACE TEMPERATURES ARE 26 
TO 27 DEGREES. A MID- TO UPPER-LEVEL STEERING RIDGE ANCHORED OVER 
MYANMAR IS DRIVING TC 06B WESTWARD. THERE IS A MILD WEAKNESS IN THE 
RIDGE OVER THE INDIAN SUBCONTINENT, AND GFS IS SHOWING AN 
EXAGGERATED POLEWARD MOVEMENT IN RESPONSE TO THAT WEAKNESS. OTHER 
GUIDANCE IS CONSISTENT IN STEERING THE STORM WESTWARD TO MAKE 
LANDFALL NEAR CHENNAI, WITH INCREASING SHEAR ALONG TRACK BRINGING 
ABOUT A WEAKEING TREND PRIOR TO LANDFALL. THE TRACK FORECAST STAYS 
SOUTH OF CONSENSUS IN ORDER TO COMPENSATE FOR THE POLEWARD TRACKS OF 
GFS AND WBAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 271800Z IS 20 FEET.

Recall of 1994 Severe cyclone - As Chennai fears from a Severe Cyclone Thane

Anyone has memory of 1994 Severe Cyclone that crossed Chennai) – It was the destructive cyclone to hit Chennai in last 20 years or even more.

This cyclone i witnessed it first hand…..to me this created havoc in Chennai. 24 cm rainfall in 24hrs coupled with 120 km/hr winds…. The cyclone scared the shit out of me. I watched the high winds with power cut without sleep. Still its scary. Hope Cyclone Thane doesnot make any destruction like this.

AWEFUL THANE :: Prevention and Mitigation

Even during this time it seems AWFUL.  It will become a powerful storm and  cause havoc for Chennai.  Precautionary measures need to be initiated now itself. Some time it may become CAT 2 storm. Government must gear up all necessary precautions before landfall to avoid live and property loss. Whether it will fizzle out or strike precaution measures are safety measures.
I pray Tamilnadu Government officials and general public to be prepared to face the storm.
  1. Store food and water.
  2. Tighten all loose bound structures in your house.
  3. Don't touch wet electrical appliances and keep away from electrical circuits.
  4. Stay out of the building if flood water enters the building and
  5. Be prepared to be evacuated to higher {KNOWN] places. 
  6. Avoid walking or driving through flood waters.
  7. Bring valuable things in a secure place well after the first caution notice.
  8. Keep battery powered lights for use during nights.
  9. Monitor weather warnings / weather alerts for better preparedness     .
        While natural hazards cannot be controlled, the vulnerability to these
hazards can be reduced by planned mitigation and preparedness measures. 
chennai - might touch a low temp of 18/17 deg C around early morning of 28-Dec... temp. now (10:25pm) is already 22.8 C ... WoW !!
