Guidance to Fishermen in Kerala and South Tamil Nadu
Between 15 to 18th October, very rough seas will seen in Lakshwadeep Sea, Comorin (Kanyakumari) Sea, South Gulf of Mannar, and in seas in South Kerala and South Tamil Nadu. Fishermen in south Kerala, Kanyakumari, Thoothukudi, Tirunelveli and Ramanthapuram are advised to follow the alerts given by the official agency and not venture into Sea, as the sea will be rough with high waves and sudden gusts of high winds.
Onset of North East Monsoon – delayed onset
With SWM still active and this UAC persisting in Bay of Bengal, the westerlies will be there till 20th, hence normal onset (15-20th October) is not possible this year. Onset is possible between 25 – 31st October.

Fastest Century by Tamil Nadu
Our normal North East Monsoon rains for Tamil Nadu is 447 mm. What a start we have got thanks to UAC near TN coast in 1st week and now the locked winds with UAC at either side. This has been a boon to Tamil Nadu and Kerala with both getting massive rains in 1st 13 days of NEM (any rains from October 1st will be counted as NEM rains irrespective of onset). Till 13th we have got near 120 mm of the 447 mm quota. Nearly 25% of the NEM rains for Tamil Nadu has been obtained even before start of the monsoon.
