#vardah stays fit as severe cyclone. Now 85% chance of landfall near #Chennai as D.Depression on noon, 12-Dec. #weather

Vardah - Severe Cyclone ! Landfall can be South of Nellore !



11:30am, #vardah - Severe Cyclone.. and marching W, WNW ... Precipitation imagery also attached ..  https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOiZQ.jpg 
https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOj0r.jpg 

Severe cyclone #vardah is now "almost" parallel to #chennai latitude !
Present pos :  12.55N, 87.11E , pressure: 987mb ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOjdl.jpg 

Factors that are going to affect #vardah 's intensity ..
1. Shear towards Chennai coast is high.
2. Dry air slowly wrapping the system.



GFS, GEM, ECMWF are in sync with near #Chennai landfall as "cyclone" on 12-Dec ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOjkH.jpg
NAVGEM, HWRF models suggest a just above Nellore landfall as Cyclone on 12-Dec .
IMD & JTWC also taking this opinion ! ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOjqI.jpg 
#Vardah - landfall can be along Chennai to Kavali, Andhra.... https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOjDi.jpg 

#vardah - During landfall, intensity of the cyclone will be reduced due to DRY air and shear near coast ! 
#Vardah - DRY air is slowly wrapping the system.
In next 24 / 36 hrs, it'll try to wrap fully !!
If this happens, it'll lose intensity, rain ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/pOjLu.jpg 

VARDHA "Severe cyclonic storm" landfall over chennai

Cyclonic storm to severe cyclonic storm VARDAH: The cyclonic storm, VARDAH over southeast Bay of Bengal moved west­northwestwards in past 06 hrs with a speed of 7 kmph.

The system is very likely to move west­northwestwards and intensify further into a severe cyclonic storm during next 12 hours. It is very likely to maintain its peak intensity upto evening of 11th December 2016. Thereafter, it is likely to weaken gradually while moving towards Andhra Pradesh coast.

It is very likely to cross Andhra Pradesh coast between Nellore and Machilipatnam around afternoon/evening of 12th December 2016. -IMD

When system starts weakening while nearing coast it would move WSW direction. Then Landfall going to be further south which will between Nellore and chennai or over chennai

Now Both ECMWF and GFS are almost in same statement on landfall track between Nellore to chennai.

Rains for chennai will be from late Sunday an better rains (Moderate to heavy) during Monday to Tuesday. No flooding rains.
