Cyclone "Thane " crosses land at 4.30 am on Friday at exacly 11.8 N and 79.7E, that is at Puducherry. While crossing, it sustained core pressure at 983 mb, which weakened rapidly on hitting land.

Currently at 8.30 am, centre of system 55 kms west of Cuddalore.

Expected west movement with weakening. Overcast in Bangalore with cool Friday and intermittent rains.

chennai - more heavy rain approaching city from S-E .. will reach in another 30 min.

Cyclone Thane .. is still having an EYE .. and not yet weakened to a Depression yet (8:30am) ... http://ow.ly/i/oETt

Cyclone is marching inland .. now 8:30am is located 50km S-W of Cuddalore and still having an EYE and NOT yet weakened to a Depression

Chennai is having strong winds and showers now 7:20am. Will continue till 12pm!

Cyclone thane is inland and centered over cuddalore at 7am. Still having cyclone strength!

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

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.

Chennai is facing gusty winds (NE) since 8.30 pm, and gusts have topped 56 kmph.

Cudalore is experiencing moderate to heavy rains, and is a cool 23c at 9 pm. Wind s are at 30-35 kmph, with gust probibility of 60 kmph.

Some strong showers on way for Pondicherry coast.. will reach around 1am.. We need some one to report directly from Pondicherry zone.

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.

Now 8:15pm, most of the deep convective bands are over W-S-W of Cyclone EYE, So chennai is having a break from strong showers.

Currently at 8.00 pm IST, "Thane "is 110 kms East of Puducherry, and has commenced its weakening phase. It is now 989 mb and surface maximum winds have dropped to 110 kmph. This weakening was expected from tonite (See previous post). 

Rainfall in Chennai ( as per Kea Station) till 8.30 pm 24 mms.

Next Update at 10.0 pm IST.

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 29^th 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 30^th 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.

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.
