1. Anti Cyclone at 850 hp levels, OLR, UTH and dry air indicates the withdrawal of South West Monsoon from Rajasthan, Kutch, Punjab, Haryana, H.P. and Kashmir.
Next phase indicates withdrawal from West M.P, Saurashtra, North Gujarat, Uttarakhand, Haryana and Delhi. (Next 2 days). Within 2/3 days, we will see strong dry NW winds blowing over Delhi.
Monsoon withdrawal will commence from Vidharbh and North Madhya Mah. and Marathwada from 1st October.
(However, due to sea level trough in the North, some agencies may not consider as Monsoon withdrawn yet. Logically, some agencies would wait for the trough to move Southwards while the Monsoon withdraws. But, at sea level, we already see a confluence of North winds and NW winds all along the interior areas of the West coast.)
