  2. I don’t know why some guys are telling its over …

    Its a cyclone..not a LPA …..

    Now this cyc movement is slow because it present very near to SL Land area..if its movement to WNM started, then the intensity and movement will be fast…

    Don’t underestimate this cyc…This is going to be a severe one..the same thing i told for THANE

  3. I lost my hopes after closing watching the experts analysis in this blog. The system has been taking tumultuous turns heading from here to nowhere..so on and so forth.
    I have been extremely pessimistic but I will be more glad to see Chennai getting drenched because of this system.

  4. Maybe not.Guys alert,the wall which is now hitting karaikal is going to marginally affect mahabalipuram. Chennai might have to wait 10 hrs approx. the rainbelt was near vedaranyam this morning.

  5.  The deep depression over southwest Bay of Bengal  moved westwards and lay centred at
    0830 hours IST of today, the 29th October 2012  over southwest Bay of Bengal near lat. 9.5°N
    and long. 83.5° E, about 530 Km southeast of Chennai ( Tamilnadu) and 270 Km northeast of
    Tricomalee  (Srilanka). The  system  would  intensify further  into  a   cyclonic  storm  and move
    westwards for some more time and then move northwestwards and cross north Tamilnadu and
    adjoining south Andhra Pradesh coast   between Nagapattinam and Nellore by 31st October,
    2012 evening/night.

  7. All of you,

    Please stop your assumptions. I have said twice today about the scenario.

    Wait and watch.

    I still stand for North TN coast to be hit. Do not worry.

    Lets start some other discussions.

    All of you be cautious of this system.

  8. Radar shows activity bay of bengal but not much approximately 150 kms to the east of chennai. Its all bits and pieces though.

  9. Ya where is Orathanadu,Thanjavur,Thiruvarur which all got 50cm plus in 2008….Btw Vandavasi 700mm seems to be out of place…There is no chance of it receiving such a heavy downpour from SWM tstorms…false reading for sure!

  10. I derive my ancestry from the Northern Most districts of TN,South Interior Ktaka and Southernmosts districts of Rayalseema…..I would definitely have heard atleast of some bit of news if Vandavasi had received 700mm…Serious case of Faulty Rain gauge!

  11. @KEA… When you take the count, is it possible to take only the useful comments? 🙂 And ignoring useless comments? 😉

  12. Looks like its southern journey has stopped (thats good news) and it has tracked only west (OK news)… at 5 PM IST it was at

    Omg!!! IMD predicting it to move south and then north,exactly what everyone thinks is going to happen! Every model now says the same.

    • hope ur expectation comes true.. but tat will be flooding the whole city and the suburbs.. also we cannot control d nature.. but we could control d flooding, which tis gov. doesnt bother…

  14. everyone is answering my questions very soon 🙂 thanks to all kea users 🙂 i feel very happy to be a member of this blog

  16. Why does IMD kill us… SRI radar not updating again.. Why they do it always during an approaching storm… Better they fix it soon.

  17. The deep depression has intensified into marginal cyclone( not severe ) and was located about 100 km East of Mullaitivu at 1730 hours today (29). It is likely to move North-westward and enter the Sri Lankan coast near Mulattivu early morning hours (around 0200hrs) causing heavy showers and strong winds over most parts of the country and surrounding sea areas.

  18. Forecast for tomorrow

    The sky condition would be generally cloudy. One or two spells of rain or thundershower would occur. Surface winds will be strong and gusty at times. Maximum and minimum temperature would be around 30 and 26 degree Celsius respectively.

  19. Iam from pondy . Here full moon is out and only light winds from NE.Yesterday we had some rain wind but today nothing. Puyalukku munnum pennum amadhi athu ethu thana illa mazhaiya varatha. From the sat image that the orange spot is in gulf of mannar. Whether it is raining anywhere in TN?

  20. Rain won’t be widespread before system crossing coast(unlike low pressure).It will rain only in 20-50 km radius .Hence no rain till now in Chennai .

  21. The deep depression over southwest Bay of Bengal moved westsouthwestwards
    and lay
    centred at 1130 hours IST of today, the 29th October 2012 over southwest Bay of Bengal near
    lat. 9.0°N and long. 83.0° E, about 550 Km southsoutheast
    of Chennai ( Tamilnadu) and 200
    Km eastnortheast
    of Tricomalee (Srilanka). The system would intensify further into a cyclonic
    storm and move westsouthwestwards
    for some more time and then move northwestwards and
    cross north Tamilnadu and adjoining south Andhra Pradesh coast between Nagapattinam and
    Nellore by 31st October, 2012 evening/night.

    2:30 pm observations. Moved NW 😀 not WSW. It was below 9 in the prev report?wasn’t it?

  22. DD REACHED THE STORM STATUS….

    TS STATUS :

    Status at 1200 UTC ( 5.30 PM IST):

    Presure : 996 mb
    Windspeed : 35 kts
    ANALYST : TS
    LAT : 8.8 N
    LON : 82.0E
    CAT : TS

    Again it reached to 35kts…its intensifying slowly..

  23. REMARKS:
    291500Z POSITION NEAR 9.0N 81.7E.
    TROPICAL CYCLONE 02B (TWO), LOCATED APPROXIMATELY 165 NM NORTHEAST OF
    COLOMBO, SRI LANKA, HAS TRACKED WESTWARD AT 09 KNOTS OVER THE PAST
    SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS FORMATIVE
    BANDING HAVE WRAPPED TIGHTER INTO THE LOW LEVEL CIRCULATION CENTER
    (LLCC) WITH DEEP CONVECTION CONCENTRATED ALONG THE NORTHERN FEEDER
    BAND. THE INITIAL POSITION WAS BASED ON THE ABOVE ANIMATION AND FROM
    A 291234Z SSMI-S MICROWAVE IMAGE SHOWING A PARTLY EXPOSED LLCC. THE
    INITIAL INTENSITY IS BASED ON CONGRUENT DVORAK ESTIMATES FROM PGTW
    AND KNES OF 35 KNOTS. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS 04
    DEGREES TO THE SOUTH OF THE RIDGE AXIS IN AN AREA OF LOW TO MODERATE
    (10-15 KNOT) VERTICAL WIND SHEAR (VWS). THE CYCLONE IS TRACKING ALONG
    THE SOUTHWEST PERIPHERY OF A DEEP-LAYERED SUBTROPICAL RIDGE TO THE
    NORTHEAST. IT IS EXPECTED TO CONTINUE ALONG THIS TRACK AND MAKE
    LANDFALL JUST BEFORE TAU 24 IN THE VICINITY OF KAKINADA, INDIA.
    DESPITE THE INCREASING VWS, TC 02B IS FORECAST TO INTENSIFY SLIGHTLY
    BEFORE MAKING LANDFALL DUE TO STRONG POLEWARD OUTFLOW, AS EVIDENCED
    ON ANIMATED WATER VAPOR IMAGERY. AFTER LANDFALL, THE CYCLONE WILL
    RAPIDLY DECAY DUE TO FRICTION AND DISSIPATE BY TAU 36. THE LIMITED
    NUMERICAL GUIDANCE IS IN FAIR AGREEMENT WITH EGRR AS THE
    SOLE RIGHT OUTLIER. THIS FORECAST IS JUST TO THE LEFT OF CONSENSUS
    AND IS LAID WITH LOW CONFIDENCE DUE TO UNCERTAINTIES IN STORM MOTION
    ASSOCIATED WITH A DEVELOPING SYSTEM. THIS WARNING SUPERSEDES AND
    CANCELS REF A, JOINT TYPHOON WRNCEN PEARL HARBOR HI 290330Z OCT 12
    TROPICAL CYCLONE FORMATION ALERT (WTIO21 PGTW 290330) MAXIMUM
    SIGNIFICANT WAVE HEIGHT AT 291200Z IS 11 FEET. NEXT WARNINGS AT
