Thunderstorms to continue in interior Tamil Nadu

Yesterday was a relatively quiet day compared to the previous couple of days with possibly few pockets of Madurai, Namakkal, Dharmapuri, Krishnagiri, Tiruvannamalai & Cuddalore districts enjoying decent spells of rains.  Neyveli enjoyed the best spell of rains clocking 67 mm rains with more than 50 mm falling in two hours between 3:30 and 5:30 AM. Similarly Cuddalore got 52 mm rains all during the early morning hours.

While there was a fairly high model consensus for rains over North Coastal Tamil Nadu and adjoining parts of South AP except for an isolated thunderstorm around Chengalpet late in the evening nothing major materialized over the North Coastal TN and surrounding areas.

Today could see the thunderstorms continue over Tamil Nadu with once again the interior areas possibly scoring better compared to the coastal areas.  As has been the case when the storms move West to East towards the coastal areas thanks to convergence off the coast we could see some of these storms intensify and give one or two places good rains.

Though the weekend looks a good prospect for places around Chennai in North Coastal TN to get a spell or two of evening convective thunderstorms we could possibly see some isolated thunderstorms make it journey from around the tri junction of AP / Karnataka / TN.

  • Anyone tracking the current storms in the radar,??

    • Siddhart

      Probably e-ne direction.Bulk of rains probably north of us..

    • Narayanan Ky

      I believe it is moving south east hence will move to pondy or below

      • Siddhart

        850hpa current winds are from west south west direction. So Ambur storms would probably provide rain to Nagar, tiruttani, tirupati!! Tiruvannamalai pop-ups will give possible rain for Chennai.

        • SrikanthK

          The ideal layer for you to watch will be 700 hPa though the storms could move on their own also if they are fairly strong

  • sriram cr

    Where it rained in Chennai today ?

    • sudar san

      rained in south suburbs i think rained at chromepet my place and other places too but bulk in north

      • sriram cr

        Good to hear

    • ~Prince~

      North chennai mostly

    • Ajith Kumar K

      Mostly all areas got good rains

  • sriram cr

    Absolutely zero rains in my place. How is this even possible !!!!!

  • ~Prince~
  • barath rakesh

    Best combinations elnino with positive iod and lanina with negative iod

    • SrikanthK

      When NEM comes I will give you enough dope on this. The two opposites cannot give the same result

      • gargara

        or maybe nem this year will be excess with lanina and positive iod and all the pundits will be shocked into disbelief. what say robin hood ? rob from west pac and give to BoB ?

        • Ajith Kumar K

          Sir suggest any sites to learn more on MJO IOD El-nino and La-Nina

  • barath rakesh

    This year positive iod only our villain.next mjo enter in indian ocean mid sep iod decrease range lets hope

  • barath rakesh

    Ukmet joined with ecmwf

  • barath rakesh

    Flash ukmet predicted very bad nem for tamilnadu.lanina modoki and positive iod combination

    • sudar san

      isnt this prediction too early

      • barath rakesh

        Just information only

    • Vivek

      Rain Gods shouldn’t betray us this time

    • SrikanthK

      No point reacting so early. Models will also change

      • barath rakesh

        Information only

  • SrikanthK

    Atmospheric conditions still looking good so fair chance for interior storms to reach the coast intact. Where it will land is a billion dollar question

  • SrikanthK

    Will the Harur storms make its journey to the coast

    • ~Prince~

      lets see

    • gargara

      South of Chennai looks better bet.

      • rohit n

        still a long way to go …let’s hope for the best

      • Leo Michaelraj

        Storms moving NE ?

        • Siddhart

          yess. And chennai could be in line for storms around 1.30 am,if it doesnt dissipate!!!

  • SrikanthK

    Parts of Bangalore seem to be getting some rains

    • Vivek

      Heavy rains for an hour in East Bangalore

      • SrikanthK

        So chaos unlimited in both cities then

        • Vivek

          I still feel Chennai is little organised in that way…..organised chaos

          • SrikanthK

            Vehicles piled up from Koyambedu beyond Padi bridge. Bypass is seeing similar scenes

  • Vivek

    I have studied quite a few on the impact of Western Ghats on SW monsoon. But is there any reading material or a research paper from IMD on the impact of Eastern Ghats on both SW and NE monsoon

    • gargara

      Not yet. But soon enough though.

  • Vivek

    Decent showers in Dharmapuri

    • Vivek

      Still a long way to catch up with it’s normal rainfall for the SWseason

  • gargara

    By the way the Ramesh report mentions that sea breeze can penetrate upto 50-70 kms into interior areas. Now all of it may not manifest immediately. How interior areas get heating during the day depends on so many factors – land use, orography present or not, presence of interior lakes or river beds – not all of this diversity is accounted for in global circulation models.

    • SrikanthK

      Thats why I always say convective thunderstorms are as complicated as cyclones and I love them so much

  • ~Prince~

    looks like some pop ups in interior around ambur

  • Padmanabhan G

    52mm for the day at West KK Nagar. Trickles continuing.

    • Selvakumar(Raijin)

      Good rainfall figures

  • Srinivas Das – Santhome

  • Padma Prasad

  • gargara

    From this sounding -http://satellite.imd.gov.in/img/Chennai.gif

    Is there a storm over sea since those coordinates are over Bay of Bengal ? Anyone in North Chennai close to BoB ?

    • Iam In Broadway close to coast and it’s raining steadily..

      • gargara

        Can you look into Bay of Bengal and see if it is raining ?

        • Can’t really.. Its dark but given that it’s widespread it should be or will rain eventually into bob

    • Srinivas Das – Santhome

      I am is Santhome, Beach facing apartments, sitting in sixth floor (Terrace) I can see the frequent lightning in the NE.

      • gargara

        So soundings are very accurate. Good to know.

  • ~Prince~

    Next 2 days there will be more widespread rains I think !!!!!

  • narayanan_ky

    Rains have started to reach closer to coast now so looks like a happy ending today with most parts getting 10 to 20 mm

  • Leo Michaelraj

    Looks like monsoon rains here

  • Leo Michaelraj

    Nunga recorded only 7 mm so far

    • narayanan_ky

  • barath rakesh

    Only light rain in ekkattuthangal

  • Harish Kumar

    Core city yet to get covered completely as per radar…. giving a long wait

  • gargara

    Here is something new from IMD – http://satellite.imd.gov.in/img/3D_aerosol.jpg aerosol concentration over India. Now there is a lot of research whether aerosols help in rain droplet growth by providing surface area. Take a look at high aerosol concentration over TN. Some red spots over there. Have those areas had rain ?

    • SrikanthK

      Some if those areas have hit rains today

  • Leo Michaelraj
  • gargara

    http://satellite.imd.gov.in/img/3Dtpw_a1.jpg

    http://satellite.imd.gov.in/img/3Dhalfhr_uth.jpg

    Huge amounts of TPW and upper level humidity across Bay of Bengal.

    Upper level wind is favorable from north east to south west. So if that mass moves in over TN expect a long night.

    http://satellite.imd.gov.in/img/3D_wvwind.jpg

  • SrikanthK

    How is the Kanchipuram storm moving anyone traking it

    • Venkatesh

      • Venkatesh

    • Leo Michaelraj

    Little heavyvcloud moves eastward

  • Pouring music @ Kilpauk and currently armed to teeth with mobile phone in cover, jacket on, blog on😉

    • narayanan_ky

      Enjoy the rainy day…!!

  • Venkatesh

    mobile application is not loading

  • ~Prince~

    Still no rains @chrompet

    • Venkatesh

      storms areconverging near poonamallee soon chrompet will get its share

      • Leo Michaelraj

        How the storms are moving

        • rohit n

          • Leo Michaelraj

            Yes flanking to the South will cover the entire city

    • rohit n

      whole city will see rains …pretty heavy one

  • Venkatesh

    Thank you Srikanth for calling me…

    • SrikanthK

  • Leo Michaelraj

  • SrikanthK

    North Chennai battered

    • mahamood ali

      After a long wait , Inuku Kathu namba Pakkam 🙂

  • jeganatharaja

    Mogappair west is getting bouncing rain.

  • gargara

    I think the sea breeze has influenced this storm more than people expected given that North Chennai is getting rains and South Chennai has not. Land use of North Chennai is producing a lot of heat and when this storm interacted with the sea breeze it got the lift it needed.

    • Last radar update when storms made a jump to East was due to sea breeze

  • Harish Kumar

    Its pouring in Poonamallee to maduravoyal belt

  • Leo Michaelraj

    Only moderate rains here

  • Venkatesh

    at last madhavaram started pounding

    • narayanan_ky

      North chennai will come up with great numbers today

      • Venkatesh

        yes.but idont when i will reach my home….hahha

        • narayanan_ky

  • Yaamesh

  • Padmanabhan G

    Raining in West KK nagar. It is almost dark here.

  • Rajeswari Sivabalan

    Will kelambakkam get anything

    • mahamood ali

      Everyone will get the Share

    • SrikanthK

      North areas stand better chance but most areas should get today I think

      • Rajeswari Sivabalan

        OK thank u

    • narayanan_ky

      From current radar storms are north west of chennai, poonamalle and kanchipuram.
      Kelamabakkam will depend on the kanchi/SRP storm movement

  • SrikanthK

    Visibility is less than 20 mts

  • SrikanthK

    Insane pounding in red hills

    • rohit n

      this is just a mammoth one …

    • mahamood ali

      Yup the storm is red Hot , Droplet would have been bigger one

  • Venkatesh

    • Venkatesh

      i hope it may cover up to nunga

    • mahamood ali

      Storm Should stand and deliver for a long time…

  • gargara

    You really have to hand it it to IMD. I mean look at this sounding location –

    http://satellite.imd.gov.in/img/Chennai.gif 13.03 80.33

    and you punch that into Google Earth and this is where it is https://uploads.disquscdn.com/images/9d795c3527f50b7331a39319174cb50452677df2701578e52f432905926353ba.jpg

    and that location over the Bay of Bengal has people, buildings over it ?

    Why ? Only they can answer this. You know when life gives you such lessons. It is time to take a break.

  • On the last radar update doesn’t the storms make eastward jump?

    • rohit n

      yes

  • Venkatesh

    Good chances for North Chennai rains and near kanchipuram RD will come to South Chennai of lucky.

    https://uploads.disquscdn.com/images/f61a5c577bfc904a4027af7628bfc13cd92722bcb8e4759a9eee07336ecd0bad.jpg

    • Ajith Kumar K

      North Chennai first attack

    • Ajith Kumar K

      Higher the cape value higher the winds or rains?

      • SrikanthK

        Higher cape means more energy

  • SrikanthK

    Polur storms to be watched

  • SrikanthK

    Do I see a east north east movement from the Vellore storms some one please check and confirm will be driving for sometime

    • mahamood ali

      Yes right it is moving ENE

  • Padmanabhan G

    Light drizzle from passing clouds at West KK Nagar. Raining at Devikapuram (between Chetpet and Polur) for the past 30 minutes.

  • Atchu,Tod hunter nagar,Saidai

    Today will be our day

  • Selvakumar(Raijin)

    Overhead thunderstorms over north Chennai

  • The ones near thiruvanamalai could be for us

    • rohit n

      yes but the one near arakonam
      looks like a red-headed beast or something

  • Venkatesh

    Nellore and surrounding had a very gud rains..hope it may crossed 50mm

  • SrikanthK

    We need little more East movement from the Vellore storms or they could possibly head north of Chennai

    • rohit n

      any chance it could move east ? because it is clearly moving away from chennai as of now

    • Venkatesh

      i hope vellore storm willgo via nagari and shar

  • Some sharp showers should be in many places going by radar…

    • SrikanthK

      Yes drop or two drizzle in Mylapore as well

  • SrikanthK
    • mahamood ali

      Gargara is not here , or else he will tell to go out and watch the clouds 😛

      • SrikanthK

        It is actually a very good idea to watch real life conditions as well because only then we can relate it better

        • mahamood ali

          That’s true 🙂

  • SrikanthK

    Time to keep a close watch on the Ambur storms

  • Padmanabhan G

    Light showers with sunshine at West KK Nagar

  • SrikanthK

    Lot of cumulus developing around the city

  • SrikanthK

    Interior storms developing around the Tri Junction

    • mahamood ali

      Sri hope today we won’t miss out

      • SrikanthK

        No guarantees lets hope for the best

  • Selvakumar(Raijin)

    Hope Kanyakumari, Dharmapuri, Krishnagiri, Nilgiris district which are only districts that have deficit over 35% which fill its cup during this weekend if the models forecast comes true

  • Selvakumar(Raijin)

    Srivilliputtur have topped today rainfall charts with 8cm

  • Selvakumar(Raijin)

    Just spoke to my father … He told this year my native is getting rains frequently… Many ponds are filled and one very large pond which is 200 meter from my house from where water is used for agricultural activities is now 3/4 filled

    • SrikanthK

      Good news Selva.

  • SrikanthK
  • SrikanthK

    Radar showing development to the south of Chennai

  • Unfortunate that the stroms in the radar right now is moving aimlessly in a NE direction. Wish it could take diversion…

    • SrikanthK

      Things look good for some sudden overhead development. Watch out

  • SrikanthK

    ECMWF expecting some serious wind instabilities in the coming days which is the reason for the high precipitation estimates

    • SrikanthK

      Dipping trough, discontinuity, UAC everything you can think off is possibly being expected

  • SrikanthK

    ECMWF thinks its NEM time, daily moderate to heavy rains over North TN / South AP over the next few days

  • SrikanthK

    South AP around Tirupati enjoying good early afternoon thunderstorms

  • SrikanthK

    The hotspot is likely to be around Tumkur to Chittoor in the North and Mysore to TVmalai in the South

  • SrikanthK

    GFS showing increased activity over West Coast

    Some Pop ups in West !!!!!

  • Vivek

    How accurate is Windy’s models ? Looks like coastal districts of Karnataka will get heavy rains today.Hope it rains well in Cauvery catchment areas as well https://uploads.disquscdn.com/images/be45f6465edba3bbcda4ae42a5bc8dc8332a6704d6469b3bfc5a142349291e4a.png

    • SrikanthK

      Windy is basically ECMWF & GFS Model outputs

  • Vivek

    Rain Clouds have enveloped whole of Bangalore sky.Lets see if it makes to the ground

  • Prabhu Vishwa
    • Malakrishnasamy

      Hoping there are good measures taken to save these waters without letting it to the sea.

    • SrikanthK

      The check dam in AP / TN border is full thats why the water is flowing now

    • Selvakumar(Raijin)

      Great to see Water flowing in Palar river.

      Is there any check dams in Tamilnadu in its path to store the water?

      • SrikanthK

        Dont think TN has any check dams except for one possibly near Kalpakkam

        • Selvakumar(Raijin)

          Then are those waters end up in sea?

          • SrikanthK

            This may not reach the sea will possibly percolate into ground as of now dont think there is enough water to reach the sea

  • Atchu,Tod hunter nagar,Saidai

    Letsee how this sustain, good consistent seen in last few runs though
    https://uploads.disquscdn.com/images/4e3bd143f35920bfcbd3ba030fb9d72b5a780ba511aee8ca2daecf4b33bfd337.png

    • SrikanthK

      Atchu you can see a faint UAC developing NW of Andaman I think this would possibly be the trigger for the next Monsoon disturbance

      • Manikandan Subbarayalu

        Next monsoon means NE monsoon ?
        Will it start early?

        • SrikanthK

          Sorry if I mis communicated, currently the Southwest Monsoon is going a break condition and to revive that normally a Low Pressure forms in the Bay. I was mentioning in that context, to revive southwest Monsoon

          • Manikandan Subbarayalu

            Thanks for your reply. Am always seeing your post morning itself.

            Our tindivanam town got good rain past week ..
            Afterthat till now no rain..
            Is there any possibility today or tomorrow?

            • SrikanthK

              Yes the next few days looks fairly good in terms of chances
