Disapperance of AN-32 in mid Bay of Bengal

It resembles quite to the Helicopter Crash in September 2009 which killed the then AP Chief minister Dr. YSR at Nallmala Hills.  The helicopter was cruising in North South Direction and facing cross SWly wind attenuated by Nallamalla Hills.
[max Ht about 1100m].   The expert committee constituted by Government also pointed out the prevailing weather then as winds from SWLy direction (orographic) and  updrafts and down drafts of Thunder cloud.
Now, AN-32 was cruising at a height about  23000ft [about 7000m=about 425 hPa]  the wind was blowing from 220/10kt on 22.07.2016/about 0900 hrs IST .  Wind veering with height was there.  One has to calculate the wind shear there. But these may not hamper the operation.  Weather may NOT be the emergency...  This may be concluded.

Vitiating SWM Rainfall distribution in Coimbatore district

The SWM rainfall distribution in Coimbatore district has always been a disputed one.  As far as I am concerned, inclusion of Valparai taluk and inclusion of heavy rainfall regions in Valparai taluk continues to boost rainfall figures during SWM period. The SWM rainfall for Coimbatore district would be around  189.6mm only; whereas the Rainfall of Valparai taluk for SWM period is around 3800.0mm.  That is nearly 20 times. The NORMAL in SWM rainfall distribution statement for Coimbatore district does not contain heavy rainfall regions in Valparai Taluk.   Valparai is the only taluk situated in the hills of average elevation about 1100 -1800 meter.  But this heavy rainfall statistics is very important and vital indicative of monsoon activity in Kerala and TN.  
By including Valparai taluk's rainfall the new NORMAL  for Coimbatore district can be deduced with the use of existing normals. (Area weighted) Once it is deduced then the question of  'LARGE EXCESS' rainfall in Coimbatore district will NOT occur.
                                                             or
If taluk wise rainfall distribution is considered then the "vitiating distribution" will NOT at all arise.

8:30pm, #Chennai - Moderate T showers seen over SW,W,NW,N from city at around from 100 to 200km. https://pbs.twimg.com/media/Cnk5eeCWcAA-PhL.jpg:large


T showers over W,SW of #Chennai are reluctant to move East towards coast.
Shower activity around Vellore is observed for past 4 hrs.
There's LWD running N-S from S Andhra to S-central Tamilnadu .. 8:30pm, Satellite IR shows T-showers all along LWD .. https://d2jhuj1whasmze.cloudfront.net/photos/normal/lgOSa.jpg

Another opposing factor for N,central Tamilnadu rains not pushing East is.. an upper-level circulation seen over SW-central Bay !
Here's the chart showing upper-level (500hpa/4.5km ASL) circulation over SW-central Bay near Tamilnadu coast ... https://d2jhuj1whasmze.cloudfront.net/photos/normal/lgP9j.jpg

Chennai - can expect rain on Monday evening, And that too if the T-cells pop very near to suburbs or over suburbs / city.
More T showers ahead for N,N-central Tamilnadu into S Andhra, S,SE Karnataka and #Bangalore on Monday, Tuesday !
