How many are tracking….if it sustains without weakening, it will reach us. I hope it sustains !!! Goodnight hopefully some rains fall over KTC belt.
Steering winds are from North to Southwards link
We have seen the template so many times, a cyclone crossing north AP or Odisha or West Bengal coast, the it activates the westerlies to surge and converge over South Kerala and Kanyakumari regions. Even this year May month Cyclone Yaas when it crossed Odisha, Kanyakumari, Ramanathpuram-Pamban, Muthupet-Vedaranayam belt got to see high winds.
Heavy rainfall
Heavy to very heavy rainfall is likely over Kanyakumari and some heavy rains will happen over Tirunelveli ghat areas and Theni ghat areas. Some parts of Tuty will get heavy rains too. South Kerala districts such as Kollam, Idukki, Alapuzha, Pathanamthitta, Eranakulam are also in the path of heavy rains.
High Winds
Sustained Winds of 30-40 km/hr are expected in coastal areas of Kanyakumari, Thoothukudi, Ramanathapuram and Delta belt around Vedaranayam tomorrow. The gusts (occasional winds) with 55-65 km/hr will be expected in coastal belts of above areas, in addition Tirunelveli will also see the gusts at times. Hence, fishermen are kindly requested to stay at home for two more days in the South TN and South Kerala coast.

Rains to Western Tamil Nadu, Kerala and South Tamil Nadu for next 4 days
From today slowly the western parts of Tamil Nadu who have remained silent this season. And even mocked the North East Monsoon will get thunderstorms. For West Tamil Nadu (Coimbatore, Nilgiris, Dindigul, Theni, Tiruppur districts) to get rains, there has to be some UAC or system in Arabian Sea for creating that pull for easterlies to come to West Tamil Nadu or create a LWD or trough along the leeward side. Remember when a circulation is North TN coast or in Central Bay mostly the coastal belts will get rains.
With an elongated UAC and trough extending along Kerala coast to Comorin Sea, this creates perfect LWD rains (Line of Wind Discontinuity) along the West TN – Kerala regions. The rains will be accompanied by Thunder and Lightening in coming days.
Next Rains for KTC (Chennai & surrounding 100 kms) and coastal Tamil Nadu including Delta is from 4th November
The next circulation will be near SW bay off Sri Lanka coast from 4th November and because of which this time not only KTC but even Pondy, Karaikkal, Cuddalore, Nagai, Tiruvarur which has subdued start with no rains so far will get rains. This spell will last for 4-5 days and rains will not only be limited to coast even some parts of interior TN will get rains.
