Cy­clonic storm to re­vive mon­soon from Nov 15

The New Indian Express - - TAMIL NADU -

THE North­east mon­soon, which has played tru­ant so far, is set to come alive as a cy­clonic storm. It is likely to head to­wards Tamil Nadu in a few days.

The well-marked low pres­sure area over the north An­daman Sea and as­so­ci­ated cy­clonic cir­cu­la­tion ex­tend­ing up to midtro­po­spheric lev­els is likely to move north­west­wards and con­cen­trate into a de­pres­sion dur­ing next 24 hours and into a cy­clonic storm dur­ing the sub­se­quent 24 hours, said a bul­letin from the In­dia Me­te­o­ro­log­i­cal De­part­ment (IMD) on Fri­day evening.

N Pu­viarasan, di­rec­tor, Agromet Ad­vi­sory Ser­vice Unit, said the de­part­ment was track­ing the move­ment of the cy­clonic sys­tem, but didn’t com­ment on whether it was head­ing to­wards Tamil Nadu.

Of­fi­cial said that heavy rains would oc­cur at iso­lated places over South Tamil Nadu, in­clud­ing Thoothukudi and Tirunelveli.

Weather mod­els predict the sys­tem to move to­wards Tamil Nadu or Myan­mar by Novem­ber 15 and kick-start the wet spell in the North Tamil Nadu re­gion, which has been out of ac­tion for ex­tended pe­riod of time this sea­son, spark­ing fear of mon­soon fail­ure.

How­ever, there is no con­sen­sus on in­ten­sity of the in­com­ing storm. The cy­clone would form in open sea and move to­wards the land. In three days, there will be clar­ity. Mean­while, of­fi­cials said strong winds from the north­east­erly di­rec­tion reach­ing 35-45 kmph are likely along and off the south Tamil Nadu coast. Rain­fall data col­lected in the last 24 hours end­ing 8.30 pm on Fri­day shows that Sirkali in Na­ga­p­at­tinum re­ceived the high­est rain­fall of 7 cm and Nan­nilam in Tiru­varur 5 cm.

The max­i­mum tem­per­a­ture in Chen­nai is 1.5 de­grees Cel­sius above nor­mal. The Nungam­bakkam weather sta­tion has recorded 31.2 de­grees while Meenam­bakkam has recorded 31.1 de­grees.

The city is reel­ing un­der deficit rain­fall of 49 per cent. Chen­nai has re­ceived 197.2 mm rain­fall as against nor­mal 390.2 mm rain be­tween Oc­to­ber 1 and Novem­ber 9. Over­all, Tamil Nadu is fac­ing a deficit of 20 per cent.

So, the re­vival of mon­soon will be cru­cial for Tamil Nadu, es­pe­cially, to sus­tain it­self in terms of drink­ing wa­ter needs and the ir­ri­ga­tion.
