28th October:

Input by Vag.Dr Vineet Kumar 👇

 Whatever on Earth happens add ElNino in it 🥴

This is totally wrong message that ElNino fueled this cyclone

We need to see other factors , earth doesnt revolve only around ElNino 

See this attached graph, it shows avg. Maximum windspeed of postmonsoon season cyclones in bay of bengal during different ENSO phases







IMD BULLETIN 

Cyclone Warning : 

Date : 28-10-2026 Time of issue : 11:00:00 Validity : 6 hrs

VSCS Arnab crossed AP and Yanam coasts near Narsapur during 0200-0800 IST on 28 Oct, with winds 125-135 kmph gusting to 150 kmph. 

Landfall completed by 0800 IST. 

It will move NNW and weaken into CS within 6 hours and DD in the subsequent 6 hours.

 27th Night Post



 Inputs from Vag.Vineet, Mitan, Shreyas 




*Cyclone Arnab with windspeed 120knots hold the record of strongest bay of bengal postmonsoon season cyclone in elnino year in satellite era (1982 onwards)

*Cyclone Arnab windspeed 120knots (as per jtwc). This is now the strongest postmonsoon season cyclone in north Indian ocean since 2019

*Cyclone Arnab along with hudhud in 2014 hold the record of strongest bay of bengal postmonsoon season cyclone in elnino year in satellite era (1982 onwards)

*As per visakhapatnam radar an outer ring seems forming around inner ring, which can trigger onset of eyewall replacement cycle


Arnab..2.50 pm IST..eye dispersing...Landfall ?


Arnab..1. 15 pm IST 27TH 

. 

*New stats alert: As per JTWC Cyclone Arnab intensification of 55knots in 24hrs is jointly the 4th most intense rapid intensification by a postmonsoon season cyclone in the Bay of bengal during the satellite era (since 1982)


27th Morning Update brief on Arnab from Vag.Vineet,Mitan Shreyas 

Based on JTWC data, Cyclone Arnab intensified by 55knots in 24hrs, this is the most intense rapid intensification observed in Bay of Bengal postmonsoon season cyclone after year 2018



Latest structure shows it has reached to Cat 3 intensity at least 100knots

* Most rain over coastal Andhra will happen before cyclone center hit Andhra

* Going to be a big one for AP coast...they haven't got such a strong storm in quite some time

*Bad underestimation for Cyclone Arnab . According to ADT it’s 100knots now with 959hpa pressure.

* Arnab pressure now 957.1hpa as per ADT analysis

*Massive rapid deepening of Arnab cyvlone in progress

*It is going through steep fall in pressure
