Yes, a very poor performance of the SWM in Sindh and specially Karachi. I believe KHI has received just 10 mms this season !

Main reason,i feel that prevented the sustems, though one was a depression, from reaching upto Sindh was the poor strength and less feeding from the Arabian Sea. There was barely any feeding from the Arb Sea.
