99B - Intensity and where it can move ?

99B is now a depression (according to IMD) and nearing Myanmar coast.

12pm, Most of convective activity is still concentrated over W,SW,NW quadrants of 99B.

T showers popping over Myanmar coast ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/ofd3t.jpg

99B - What next?

It'll track NE for 24hrs and then North or NNW into North Bay on 25-Oct.

As shear is low, it'll intensify to Cyclone.

For 99B..

GEFS expects the system to track NNW and crash into S Bangladesh... https://d2jhuj1whasmze.cloudfront.net/photos/normal/ofdjs.jpg

HWRF model suggests or confused about the track "after 99B reaches Cyclone and drifts into N Bay" ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/ofdmk.jpg

UKMET model suggests a WSW drift after 99B reaches North Bay as a Cyclone ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/ofdsH.jpg

Why models are confused?

All because of the 2 ridges and the 99B is struck right in-between ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/ofdzL.jpg

Next 2 days, scattered T showers expected over central,N-central,W-ghats Kerala and into Nw,W,central,SE,central-coast Tamilnadu ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/ofgFX.jpg

Now focus shifts to 99B in Bay, at present in central Bay as a LOW ... Low level circulation is exposed with convective activity over West ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/od8qJ.jpg

9pm, IR shows still convective activity is over W,SW.

It's pull effect is giving T showers over Kerala and S,central,SE Tamilnadu ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/od9Ag.jpg

99B is expected to gain intensity slowly with an initial movement of NE towards Myanmar coast.

Typhoon Haima, Bay - 99B and NE monsoon delay !

Typhoon #HAIMA is nearing China coast near to HongKong ... Landfall expected in next 18hrs .. 
https://d2jhuj1whasmze.cloudfront.net/photos/normal/oajB5.jpg .. 
https://d2jhuj1whasmze.cloudfront.net/photos/original/oajEO.gif 

This Typhoon has popped a LOW in our central Bay of Bengal as well, it is tracked as 99B ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/oajYH.jpg
This 99B is trying to establish/consolidate even though the low-level wind gush is still happening from S Bay to that Typhoon ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/oalue.jpg

At present 99B is a LOW with pressure around 1004mb.

Expected movement is NE during next 2 days towards Myanmar coast !

https://d2jhuj1whasmze.cloudfront.net/photos/normal/oamEB.jpg 

99B, Models suggest a North or NW re-curve after nearing Myanmar coast ... this will even delay the easterlies "NE Monsoon" into SE Bay. 99B 's expected re-curve may not happen if it fizzles out along Myanmar coast along with Typhoon Haima over China !

Has to watch till 23-Oct.

During next 2 days, due to pull effect of 99B, Kerala can have SW Monsoon style showers and HEAVY T showers along W-ghats Kerala, Tamilnadu ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/oaoOP.jpg

During next 2 days, scattered T showers expected to pop over central,W,SE, S Tamilnadu !
