The south west monsoon seems to be making a hasty retreat, from its normal widhdrawal region. Its the last week of August, and , according to the winds and the north-south trough over Pakistan, the monsoon seems to have already retreated from the region west of the international border. the Iran/Pakistan coast is getting north-south winds from the land to sea, thus raising the temperatures in region, with Norkundi at 42c.The 925hpa streamline shows a disorganised monsoon trough.
Cola, forecasts a diminishing of rainfall over Rajasthan in the last week of August and a lessening of rains over Gujarat and regions around west M.P. and north Maharashtra in the first week of September. Also, the jet streams at 200hpa levels, show signs of weakening, and forming a high over India at 30N, thus collaborating with the view that the monsoon trough is disintegrating. The west- east jet streams is approaching the 30N region, that is moving south.
If the scene prevails, we are to see a widhrawal of the monsoon from the north-west in the next 10 days, about a week before schedule.
