One of the Wettest day awaits Chennai

One of the Wettest day awaits Chennai – Be prepared

The weather bloggers have been waiting for November 12th from last week of October even before the system was taking shape far way in Thailand Sea. In a short-while after mid-night Chennai will witness the 1st spell of rains from this system. The good news is that the system is not going to become a cyclone and rains will last for prolonged period of 3-4 days.

Chennai: Starting from mid-night right now heavy rains will lash the city intermittent throughout the day. Our Kea blogger cyclone expert Selva expects around 80 mm rains. I also expect around 100 -120 mm rains tomorrow (ending 8.30 am on 13th) and there is good chances for the roads to get flooded in low lying areas.

Tamil Nadu: The system is expected to move into arabian sea after 2 days, before that all coastal areas will get good rains on 12th and 13th. After that it will the Interior regions chance for heavy rains. There can be very very heavy rains in Nilgiris district, Kanyakumari district, Theni district, Coimbatore district and Tirunelveli district’s as the system moves away during 13-14th.

  1. Surprised that IMD AWS has recorded only 1 mm so far although from radar animation we could see a storm pass thru Nunga.. KEA metsite has recorded 6 mm. First spell for today will start in the next half hour.

  2. First heavy spell of the day started… Series of thunder storms approaching. Should get a big one later during the day…

  3. South Chennai should be dry now….Kelambakkam , Navalur , Medavakkam , Tambaram – no cloud cover at these places. will pick up after 1 hour

  4. Good morning.
    There was a monstrous spell in BN between 11pm and 11.45pm yday night..Light rains are continuing on and off.My RG is showing 38mm

  5. System no longer exists from a technical perspective….there are Huge rain bands to our east.Need to check if these can gain strength and come to the Coast

    This is a new link available in RMC Chennai for the past one month. Even before that it was available as a beta version for some time. Developed by one of our new staff member Srimanta Halder with the help and guidance of Shri S.B. Sb Thampi DDGM RMC Chennai. You can get instant weather of Chennai in this link.

    The weather observations from Nungambakkam AWS is updated every 30 seconds here. I was waiting for a rain spell to put a post in FB. I request all my friends to enjoy this facility and put their comments for any improvement in the display.

  7. SOI of -10 has definitely weakened the system and pulled it to Srilanka.

    The “system” is now interacting with the eastern coast of Srilanka.We should just sit back and hope a few rainbands can bring good rains to us during the day.

  8. Guys…Please do not give up on WP99…there are enough rain bands on the sea.
    There are 2 big blobs which are worth 100-200mm..lets see which Coast gets lucky with those moisture tanks

  9. before an hour they have started heavy rains with winds in adyar at in sunnews…
    hope they declare holiday in next half and hour..
    will the rain increase in next half an hour>

  10. it has been a cold day in topeka , kansas. Temperature is going to remain below freezing for next couple of days due to artic blast

  11. western part of circulation interacting with lankan landmass n so it looks ill n scattered ..convection been supported with gud divergence and so tis hvy rains r not going to stop anyway for next 8- 12hrs as for north tn is concerned..

  12. THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.8N 91.4E, IS NOW LOCATED NEAR 10.4N 85.9E, APPROXIMATELY 360 NM EAST-SOUTHEAST OF CHENNAI, INDIA. RECENT ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS FLARING CONVECTION OVER A BROAD AND ILL-DEFINED LOW-LEVEL CIRCULATION CENTER THAT REMAINS PARTLY EXPOSED. UPPER-LEVEL ANALYSIS REVEALS A MARGINAL ENVIRONMENT WITH DIVERGENT EASTERLY OUTFLOW. HOWEVER, MODERATE (15 TO 20 KNOT) EASTERLY VERTICAL WIND SHEAR IS DISPLACING THE ASSOCIATED CONVECTION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

    • hi thala, a small part of the circulation is interacting with land, but most of it is still in the sea. There is very low shear with good convergence and divergence too, heavy rainbands currently in its NE quadrant, however more will develop to hit us tonight or tomorrow morning

      • it seems tat entire rains parallel to n.tn coast will hit the coast as new storms forms as the day passes

      • I think our main show awaits tonight as others have been saying, and a special show as in organized thunderstorms followed by long hours of moderate rains

  13. Guys, these are just the outer bands giving us rains! in fact only chennai is getting rains at the moment! So chill.. The main bands are still a good 500-600 Kms away! Moreover, with the abundant moisture available in TN coast, the convection is expected to explode as it nears the coast.. No dry air/ any other villains whatsoever! Dont get duped by the Satellite Image at present!
