The burst in monsoon activity on display mostly in central and adjoining west India for the past month may not last later than the next week, say international models.
Outlook by the US national agency indicated that the heavy rain may gradually lift over north-west India.
A fresh spell may break out over South India during the next week.
Latest conditions suggest there might be yet another rain-generating low-pressure area for the asking but mostly forming over land in east India and moving north-northeast.
This would rustle up monsoon activity over north-east India, adjoining east India and along the Himalayan foothills.
Alongside, a spell has been indicated for South India from August 11 lasting three to four days but petering out to join the lull that would have befell the north-west.
During the lull phase, the rains are seen being confined to only the West Coast, east and north-east India and parts of the East Coast as well.
No monsoon break The lull phase could be mistaken for the ‘monsoon-break’ in which the rains shut out for a prolonged period during mid-season.
The ‘break’ comes about after the monsoon runs over a peak, and ‘takes a pause to breathe in’ before reviving over the west coast.
Meanwhile, the depression has weakened on Thursday afternoon into a well-marked low-pressure area. It would weaken further to a conventional ‘low’ by Friday.
An upper air cyclonic circulation has already formed over northwest Bay of Bengal ahead of a successor ‘low.’
India Met Department sees the system not surviving for long. It may merge into the monsoon trough to scale up rains in the north-east and along the Himalayan foothills.
The rain deficit has reduced to 18 per cent for the country as a whole as of Wednesday evening. Central India made the largest gains out of the steamroller-run of the monsoon, compressing deficit to just four per cent there.
North-West still lagged far behind with 32 per cent, leaving contiguous Punjab-Haryana-Delhi-Uttar Pradesh quite in the red.
A welcome aspect thrown up by India Met Department statistics are that the last Met subdivision under the ‘rainfall scanty’ category has been wiped clear of the map.
Another is that the revved up monsoon since early July has generated the first ‘rainfall excess’ Met subdivision in Odisha (+25 per cent).
