It is into these patently welcoming monsoon settings that a new minimal-strain region most likely forming in the Bay by Wednesday would toss by itself in, to retain the monsoon trough alive above the plains of North India and maintain the heavy to incredibly heavy rainfall.
Sustained rains above the last handful of days have served the rainfall deficits to reasonable to 26 per cent above Himachal Pradesh 50 per cent above the Union Territory of Jammu & Kashmir and sixty seven per cent above Ladakh.
