Hold-up in the monsoon continued for a fourth day over peninsular India, but may lift over the next three days as flows strengthen.
The offshore trough along the Konkan to south Karnataka coast made for a feeble formation on Sunday, signalling the weakened state of monsoon.
Lost momentum
But the seasonal weather system is busy recouping the momentum it had lost to a freak cyclone spinning up along its way in south Indian Ocean.
Piloting showers of a reviving monsoon would start bearing down on the west coast as well as east and east-central India over the next few days.
The rain spell may start peaking towards the weekend, with a full-fledged monsoon current entering east-central India.
A good augury is the changing coordinates of a rain-bearing cyclonic circulation, which has moved in from east to drop anchor over west-central Bay of Bengal.
From here, it would be ideally positioned to probe the southeastern coast and, as per some forecasts, even penetrate into peninsular India with a rain-head.
Further advance
But its behaviour needs to be monitored and ascertained over the next few days for taking a final view in the matter.
Meanwhile, the northern limit of the monsoon continued to be stuck across Harnai, Satara, Belgaum, Agumbe, Madikeri, Kodaikanal and Gangtok on Sunday.
The India Meteorological Department (IMD) said that conditions are favourable for its further advance interior Karnataka and entire Tamil Nadu over the next three days.
It would also cover parts of south Andhra Pradesh, entire south Bay of Bengal and more parts of central and North Bay of Bengal during this period.
Heavy rain
An IMD weather warning said that heavy rainfall might lash one or two places over the Andaman and Nicobar Islands on Monday.
Forecast for the next two days predicts rain or thundershowers at many places over Kerala, coastal Karnataka, Konkan, Goa and coastal Andhra Pradesh.
Rain or thundershowers would also occur at a few places over south interior Karnataka and at one or two places over rest peninsular India.
The rains will scale up along the west coast, interior peninsula and adjoining east India from the weekend.
