  1. The rains will begin in chennai from Monday or Tuesday and increase into heavy intensity from wed or Thursday in chennai!

      • From my experience in 2011 same like that happened in 2011 low formed and heavy rain started in chennai from 24th! Nov

      • Date wise low likely to form in GOM! imd chennai also agrees that rains will increase in chennai from coming Monday or Tuesday!

      • yeah but magicseaweed expects this low to be quite low in latitude thats what worries me

      • Don’t worry everything will be fine at that time always when low comes to GOM chennai gets pounded like anything!

  2. think when the monsoon started we had SOI of -8..pls correct me if i am wrong..this dipped to less than -10 guess…now it is again back to nearing -8

  3. Good morning all, good title to thread today, absolutely right, hopes receding by the day for chennai. Each day now dawns with blue skies.

  4. It’s bright and sunny in periyapalayam. Last night was warm compared to previous days and there was not much mist in the morning either

  5. 3 circulations in this monster trough – 1 NE of Maldives which could pound S TN
    Another one SE of Sri Lanka which is a minor one and could trigger some isolated thunderstorms in N, C TN.
    One SW of Aceh

    • Susa will chennai get rains from this SE circulation? Imd chennai tells rains will begin in chennai from Monday or Tuesday and increase the intensity from wed in chennai!!

  6. Again, a humid night with mini hovering around 25deg, I feel chances are bright for a convection; more over yesterday there were millions of flys around (‘eesal’ in tamil) this is indicative of rainy days. I may sound unscientific. Let us see.

  7. Upper Tropospheric Ridge centered around the Philippines and the associated Ridge axis is still seen running approximately around 13 – 14 deg N latitude ……

  8. Latest GFS takes he bulk precipitation region down south of Comorin ….

    Sri Lanka is expected to get maximum from this Low ……

    Southern most districts of Kerala and TN have a chance of rain ….

  9. Historic Rains lash South Tamil Nadu, ending 8.30 am on 21.11.2014
    ====================================
    The trough of low at mean sea level over equatorial Indian Ocean and adjoining central parts of south Bay of Bengal has become less marked. However, a cyclonic circulation extending upto 0.9 km a.s.l. lies over southwest Bay of Bengal off Sri Lanka coast. Nambiyar in Tirunelveli is seeing floods after 22 years. Pechiparai Dam is just 1 feet away from overflowing.

  10. That Low near GOM , for a short while seems to be momentary one …going along with the actual low ….

    Rains set to hug along the coast of TN for a while ..

    • Actually I haven’t looked at it …
      But I heard it form Sel, that it could be due to warmer anomalies in the eastern pacific….
      In that case the energy would not be accumulating in the western Pacific …as no stronger subsidence is taking place over the eastern pacific ..
      Energy is spread over the Pacific, rather than accumulating in western Pacific …
      I feel this may be one of the reasons , but I haven’t looked into parameters like instability in the atmosphere, which is also one essential component required for some activity ….

      • last year it was completely upside down. western pacific was very warm during oct,nov,dec. conditions wer looked like lanina. tat led to historic monsters like haiyan

      • Sel, any more details on how that “La Nina like” conditions emerged at around that time ??

      • entire year followed neutral state but lanina like conditions evolved during boreal fall wen eastern pacific failed to maintain the sst..so tis drived the trade winds twrds w.pacific n strengthened it.. and tis collectively led to accumulate the energy in w.pacific .. last year v got most of the pulses from w.pacific.

      • Even though bay is silent, we get pulses from pacific, its like kaanji pona nadhi, andha vathada kadalai paathu aarudal adaiyum, aana atha kadale vaathi pona? Similar situation is between bay and Pacific

  11. @Jeet…when i was in trichendur i prayed to lord muruga that we should cross 120 cms this season…but seems he is doing it only in his area. tirunelveli,trichendur,tuticorin..keeping my fingers crossed…

  12. chennai and other adjoining districts would be under wet spell within a day or two. probably next week we will have plenty of useful heavy rains. Moon is entering favourable position from tonight for another 21 days. 23rd November 2014 – 16th December 2014 considered to be heavy rainfall season for whole of north tamil nadu.
    ss

  13. Some improvement in weather today and some dense cumulus around after system over lakshadweep started to weaken.

  14. In December kalpakkam to nellore sketch has high percentage of cyclone chances are higher because we had more dry days as of now we are in treat in December second week

  15. Let wait for another two week we have good chances of rain, all are disappoint last three yrs of not good rains for Chennai but it will huge it will get flooding rains waiting for Chennai in December

  16. Lets enjoy other places like south coastal tamilnadu, central tamilnadu and deltas region enjoy the rains they need badly ,don’t lose hope guys lets think positive i am also negative comments most times but we all post positive comments all the dreams come true very quick.

    • Chennai people are more greedy, they had great rains just 5 days back and they are expecting rains everyday and also wanted cyclones 🙂

      • There are many ppl who will be active only if it rains in native district..
        if greedy why PJ is collecting rainfall data all over and not only for Chennai..Many here were happy abt rains in delta districts,ramanathapuram,thirunelveli district..
        Nov is wettest month in Chennai and people are expecting the same to happen…

      • I appreciate the efforts of great bloggers here, am always for rains but not cyclones, may be over enthusiastic.

  17. Hey some one explain me what is super cellular thunderstorm why it is not occurring in chennai?

  18. latest satellite picture gives lot of positive signals, as we could see dense cloud mass over south east bay of bengal. needs to be tracked. we will have rains from tomorrow.
    ss

    • v can expect like tis..convection along the itcz is intensifying as days getting progressed. it will be great if a system forms in s.east bay from the present vortex..

      • it is not a necessary condition.. v had cyclogenesis in bay and arb sea irrespective of the mjo phases.. it just boost the conditions for cyclogenesis when it passes. always the favourable conditions matters

      • yeah..tats the general saying but it is not mandatory in all cases.if v go with the past history, mjo 3 n 4 is the ideal condition for bay but at the same time all the conditions has to be inline.

      • Yes but models showing vortex near SE arabian sea developing into a system instead of SC BOB vortex.

    • I am seeing some cloud activity here. It is due to MJO wave?. So There is a change in str movement ?. Will it adopt its own style to reach NW direction instead of current condition?

      • mjo convection vary from normal convection,..it has some typical features ,and now it is constrained to itcz area of convection but overall it increases the probablity of cyclogenesis

  19. Heavy rain lashes southern dists; water level rises in dams
    m.timesofindia.com/city/madurai/Heavy-rain-lashes-southern-dists-water-level-rises-in-dams/articleshow/45236056.cms

  20. For the past few days, people on streets talking about heavy rains in South TN…
    Just now heard one lady saying to somebody..”Hey..theriyumaa..Thanjavur’la nalla mazhayam…”
    :O: :roll_eyes: :O:

  21. Ada ponga pa..no work in blog this weekend..so ellaarum poi “Appuchi’s Village” and “Beware of Dogs” Tamil movies paarunga 😀

  22. Good rains possible for N TN from November 28th-November 30th.Current system building in SE BOB will be the cause

  23. We are still having heavy rains in the south. Looks like it will continue like this for a couple of days at least.

  24. @arun0521,

    I didn’t say anything about rains. That was IMD prediction of Wednesday that it will rain heavily on Thu and friday. As you can see they have been way off target as far as chennai is concerned

    • but rest of the models( GFS, Parallel GFS, NAVGEM, CMC) ruling out this disturbance instead they’re expecting arabian sea system to become a severe cyclone.

      • I think ECMWF will get this right this time because it was forecasting hpa to develop in Arabian sea in coming days. We can clearly see from the navy nrl image dry air entering north arabian sea which will lead to strong hpa.

      • more over the hpa wich was extending from east northeast has reduced ..so the str would move north,paving way for the trough to expand north..tis will do good for north tn in terms of rain

  25. Very heavy rain for south coastal tamilnadu central tamilnadu delta region light to moderate rain for marakkaom to sriharikota sketch for coming days

  26. After November 3rd week, you only get ‘Hazy’ light grey clouds ,as it is happening now. Only light rains are a possibility from now onwards. ‘ADAI mazhai’ will not happen.

  27. Rainfall decreases and increase from 26th over South coastal Tamil Nadu and No significant change for rest Tamil Nadu.

  28. Ehsan will it rain or not this month end…..Take one stand….! We are saying it will. But your header says, the deficit will increase.
