THANE 30122011/0625 hrs IST

The cloud mass centre may be approximately EAST of Kalitheerthalkuppam [Cuddalore] at about 80KM. Now it is the phase that Easterly winds will enter.  Maximum sustained winds of 125 KMPH must not be confused with surface winds since the maximum sustained wind is a parameter only ON SMOOTH WATER only. Within another THREE to FIVE hours from NOW 90% of clouds will be cleared and perhaps (sometimes) sun shine will come. 
This is a  cloud mass [not tightly organised to produce gale winds or torrential rains] slowly diffused.

Cyclone thane going to cross just south of cuddalore in another 2hours

Thursday, December 29, 2011

Reviewed at 10.pm IST, "Thane" is about 100 kms East of Puducherry. Notching up slightly, Pressure at 986 mb, the surface winds are 125 kmph, both parameters strengthening in the last 2 hrs.

Tracking slightly Northwards, 12.3N now), at about 10 kms per hour (currently), it can be assumed to cross the coast South of Chennai by early Friday Morning.

It's almost a repeat of Cyclone JAL for Chennai. From 8:30am today city has recorded only 2.4cm till 9:09pm. Too early to decide ??!!
Cyclone Thane is slowly starting to weaken, pressure has increased from 982mb to 989mb, and wind speeds have reduced to 110km/hr
chennai - will not have any strong showers till 1am ... and will pickup towards morning! Ground winds will be upto 35km/hr till 1am.
chennai - Now most of the showers are concentrated over W-S-W of EYE of Cyclone.. so showers are for Pondicherry coast only at the moment.

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.

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.
RT @gravikumar: we've been seeing nice drizzles around Adyar, Chennai area since early this morning. Its also windy and totally a chill.

THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS 
TIGHTLY CURVED BANDING WRAPPING INTO A WELL-DEFINED LOW-LEVEL 
CIRCULATION CENTER. A 281208Z SSMIS IMAGE SHOWS AN IMPROVED, THOUGH 
ASYMMETRICAL EYEWALL WITH THE BULK OF THE DEEP CONVECTION OVER THE 
WESTERN SEMI-CIRCLE. THIS IS DUE TO WEAK, EASTERLY VERTICAL WIND 
SHEAR (VWS). OVERALL, THE UPPER-LEVEL ENVIRONMENT HAS IMPROVED WITH 
DECREASING VWS AND NEAR-RADIAL OUTFLOW AND, BASED ON THE SSMIS 
IMAGE, THE SYSTEM IS NOW VERTICALLY ALIGNED. THERE IS HIGH 
CONFIDENCE IN THE CURRENT POSITION BASED ON A SMALL MICROWAVE EYE 
FEATURE IN THE SSMIS IMAGE. THE CURRENT INTENSITY HAS BEEN INCREASED

INTENSIFY SLIGHTLY TO A PEAK INTENSITY OF 80 KNOTS BUT COULD 
INTENSIFY AS HIGH AS 90 KNOTS IN THE NEXT 24 HOURS. RELIABLE 
INTENSITY GUIDANCE PEAKS THE INTENSITY AT 75-80 KNOTS AND MAINTAINS 
THIS INTENSITY THROUGH TAU 24. AFTER TAU 24, TC 06B WILL BEGIN TO 
WEAKEN AS IT INTERACTS WITH LAND AND SIGNIFICANT WEAKENING WILL 
OCCUR THEREAFTER WITH DISSIPATION EXPECTED BY TAU 48 AS THE SYSTEM 
TRACKS OVER ROUGH TERRAIN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT

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.

271500Z POSITION NEAR 12.3N 86.3E.
TROPICAL CYCLONE (TC) 06B (THANE), LOCATED APPROXIMATELY 375 NM EAST 
OF CHENNAI, INDIA, HAS TRACKED WEST-NORTHWESTWARD AT 04 KNOTS OVER 
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
CONTINUES TO INDICATE A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER 
(LLCC) WITH IMPROVED DEEP CONVECTIVE BANDING WRAPPING INTO THE 
CENTER; HOWEVER, BASED ON A 271221Z SSMIS IMAGE, THE LLCC IS BROAD 
AND REMAINS ON THE EASTERN EDGE OF THE DEEP CONVECTION DUE TO LIGHT 
TO MODERATE, EAST-SOUTHEASTERLY VERTICAL WIND SHEAR. DESPITE 
THE IMPROVED ORGANIZATION, THERE IS FAIR CONFIDENCE IN THE CURRENT 
POSITION DUE TO THE BROAD NATURE OF THE LLCC AS DEPICTED IN A 
270327Z ASCAT IMAGE. THE CURRENT INTENSITY IS ASSESSED SLIGHTLY 
HIGHER THAN THE DVORAK ESTIMATES OF 55 KNOTS FROM PGTW AND KNES.
TC 06B IS FORECAST TO TRACK WESTWARD UNDER THE STEERING INFLUENCE OF 
A DEEP SUBTROPICAL STEERING RIDGE EXPECTED TO BUILD TO THE NORTH 
WITHIN THE NEXT 24-36 HOURS. THE BULK OF THE DYNAMIC MODEL GUIDANCE 
IS IN GOOD AGREEMENT WITH THE WESTWARD TRACK. GFS HAS TRENDED TO A 
MORE WEST-NORTHWESTWARD TRACK OVER THE PAST FEW RUNS AND IS ON THE 
NORTHERN EDGE OF THE AIDS ENVELOPE. WBAR REMAINS THE SOLE OUTLIER 
WITH AN UNREALISTIC RAPID RE-CURVE TRACK INTO BANGLADESH. THE JTWC 
FORECAST FAVORS THE ECMWF, GFDN, UKMO AND NOGAPS SOLUTIONS AND IS 
POSITIONED SOUTH OF THE MODEL CONSENSUS TO OFFSET WBAR. TC O6B IS 
EXPECTED TO INTENSIFY SLIGHTLY OVER THE NEXT 24 HOURS DUE TO GOOD 
OVERALL POLEWARD OUTFLOW, BUT SHOULD WEAKEN AS IT APPROACHES THE 
INDIAN COAST. NEAR TAU 72, THE SYSTEM WILL DISSIPATE RAPIDLY DUE TO 
LAND INTERACTION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 271200Z IS 17 
FEET. 



IMD warning, 7pm

RSMC TROPICAL CYCLONES, NEW DELHI - Remarks
--------------------------------------------------------------------------------------
CONSIDERING THE ENVIRONMENTAL FEATURES, THE SEA SURFACE TEMPERATURE IS ABOUT 27-28 DEG. C. OVER THE REGION. IT IS RELATIVELY LESS TOWARDS TAMIL NADU AND SRI LANKA COAST BECOMING 26-27 DEG. C. THE OCEAN THERMAL ENERGY IS 50 - 80 KJ/CM SQUARE AROUND THE SYSTEM CENTRE. IT IS 50-80 KJ/CM SQUARE TO THE WEST AND WEST-NORTHWEST OF SYSTEM AND LESS THAN 50 KJ/CM SQUARE NEAR TAMILNADU AND NORTH SRILANKA COAST. THE MADDEN JULIAN OSCILLATION INDEX CURRENTLY LIES OVER PHASE 5. AS PER STATISTICAL AND NWP MODEL PREDICTIONS, IT IS EXPECTED TO LIE IN PHASE 5 DURING NEXT FIVE DAYS. THE PHASE 5 IS FAVOURABLE FOR INTENSIFICATION, AS PER OUR PAST STUDIES. THE UPPER TROPOSPHERIC RIDGE LIES ALONG 15 DEG. N AND HENCE HELPS IN WEST-NORTHWESTWARD MOVEMENT OF THE SYSTEM. THE LOW LEVEL CONVERGENCE AS WELL AS UPPER LEVEL DIVERGENCE DOES NOT SHOW ANY CHANGE DURING PAST SIX HOURS. THE VERTICAL WIND SHEAR BETWEEN 200 AND 850 HPA LEVELS IS LOW TO MODERATE (10-15 KNOTS) AROUND SYSTEM CENTRE. THERE IS NO SIGNIFICANT CHANGE IN WIND SHEAR DURING PAST 24 HRS. CONSIDERING THE NWP MODEL GUIDANCE, MOST OF THE MODELS SUGGEST THE INTENSIFICATION OF THE SYSTEM INTO A SEVERE CYCLONIC STORM BY NEXT 24 HRS. HOWEVER THEY SUGGEST SLIGHT WEAKENING BEFORE LANDFALL. WITH RESPECT TO TRACK, MOST OF THE MODELS SUGGEST WEST-NORTHWESTWARD AND THEN WESTWARD MOVEMENT. A FEW MODELS SUGGEST NORTH-NORTHWESTWARD/ NORTHWESTWARD MOVEMENT. THE CURRENT FORECAST IS IN AGREEMENT WITH THE NWP MODELS OF FIRST CATEGORY AND SYNOPTIC GUIDANCE.
