The monsoon is coming into its own along the West Coast as well the East with its northern limit advancing beyond Mumbai to Dahanu in Palghar district of Maharashtra on Monday.
An India Met Department update said that the northern limit passed through Dahanu, Malegaon (Maharashtra); Pachmarhi, Jabalpur and Sidhi (Madhya Pradesh); and Patna and Raxaul (Bihar).
The monsoon has thus advanced into Konkan, Marathwada and Vidarbha; most parts of Madhya Maharashtra; some parts of south-west Madhya Pradesh and more parts of east Madhya Pradesh.
Conditions are now favourable for it to enter south Gujarat, the remaining parts of Madhya Maharashtra; some more parts of Madhya Pradesh and east Uttar Pradesh; and the rest of Bihar over the next two days.
The rain over Central and East India is being spearheaded by a cyclonic circulation that moved in expectedly from the Bay of Bengal and that was parked over Vidarbha on Monday.
Heavy precipitationThe IMD has forecast heavy to very heavy rain over East and North-East India and along the West Coast during the next four to five days.
Most parts of North-West India are also expected to receive moderate to heavy rainfall during this period, though not quite monsoonal.
This is because of the moisture brought in by the cyclonic circulation over Vidarbha, which is forecast to move north.
The moisture will get directed into an existing trough extending from North Rajasthan into West-central Bay of Bengal, where it will lifted and cooled to pour as rain.
Himachal Pradesh, Uttarakhand, Punjab, Haryana and Delhi will be benefited in this manner ahead of the arrival of the monsoon in the region.
Meanwhile, the Met has said in Monday’s outlook that a fresh cyclonic circulation will materialise over the Central Bay of Bengal over the next two days.
‘Low’ look-outThe European Centre for Medium-Range Weather Forecasts has been pointing to this possibility over the last few days but it had gone on to suggest that it could grow into a low-pressure area by the weekend.
On Monday, it has extended the outlook for the ‘low’ by another four to five days.
A storm tracker featured by the US Centre for Climate Prediction appeared to support the forecast of a ‘low’ that would meander to the Odisha coast and cross make landfall over the next eight to 12 days.
