Posted Monday 4th  Night:

Initial Basic developments observed for South West Monsoon Withdrawal:

1. An Anti Cyclone has formed in the 200 level jet streams over Sindh Region. This will move and create an upper air trough (at that level) in next 2/3 days which may form along the 25N line....thus transforming the Jet streams to Westerlies.  Anti cyclone could form/slide in lower levels.

2. Moisture decrease in NW region observed.

3. Drier air (SWest/ West) along NW India is bringing less rains in Northern India plains. The rains are restircted to the Himalayan Hills, as the Monsoon Axis n in the foothills.

 Monsoon withdrawal may start from Sindh/West Rajasthan from 8th/9th September.
