Dear Sir, you said in your previous post that "South West Monsoon may withdraw from Sindh and West Rajasthan by around 10th September. Will update on this again on 8th". You haven't updated on this in your post of 8th September. Could you please let us know when the South West Monsoon will withdraw from Sindh?

abizer/vinod/sunny/Hrishikesh: : A rush of moisture from the Bay, and coupled with the formation of an UAC in the mid Arabian Sea has brought clouding to Maharahtra. Upper air temp along coast remained at 18c at 850 level.
UAC has formed around the 62E and 19N location. Moisture laden winds from the Southern segment of this UAC are rushing towards the West West Coast of India (specially Northern parts).This, alongwith a rush of moisture from the Bay , has brought shallow clouding in Maharashtra. Clouds in Vidarbh are gaining height though.
As the winds approach the coast, they turn NW in direction due to the strengthening UAC (BB-11) off the AP/Odisha coast.
Clouds movement in Mumbai is therefore NW direction.
A few patches of heavy clouds formed and brought heavy rains in some areas along the North Konkan region. This may be due to the sudden cloud cooling at upper level from extreme land heating below.

Prasad: Rains expected to increase in Mah from Sunday as BB-11 moves in.These are not withdrawal showers.

Majid: Waiting for another 2 days to see BB-11 track.

Still we do not have logical reason why SWM has totally eluded Southern India. Situation is so bad in Cauvery that Vishwarayana canal which irrigates Mandya is totally dry!
All models failed to predict monsoon failure over south india.

However PK Nandankar from IMD Pune says:
Weaker than expected La Nina, negative IOD resulted in scanty rains over southern India - which is in correct as per theory this should have resulted in more rains.

Now with BB11 ready to reach MAHA/GUJ - SWM will still hover central India giving no chance to down southern parts.

Just saw vageries 2015 blog - september resulted in very good rains over Marathwada/GUJ now we r seeing similar pattern. (BB6)
