Strong winds continue to prevail over South-West and adjoining East-Central Arabian Sea (around Lakshadweep Islands and farther South-West), rustling up high waves signalling the approach of the next monsoon ‘pulse.’

On Thursday, heavy rainfall is forecast at isolated places over Kerala, Coastal and South Interior Karnataka, Coastal Andhra Pradesh, Konkan and Goa, Telangana, Bengal, Sikkim, Odisha, Assam, and the North-Eastern States.

Fulcrum in Bay

The rains would grow in intensity around a low-pressure area popping up over the North Bay of Bengal during the next three days. Monsoon flows being directed into it from the Arabian Sea will result in heavy rain over the West Coast and the adjoining interior.

The 24 hours ending Wednesday morning saw the flows beginning to converge on the West Coast dump heavy rain along Kerala and Karnataka. Main stations recording heavy to very rainfall (in cm) during this period include Vadakara (Kerala): 16; Agumbe (Karnataka): 10; Cannur (Kerala): 7; Shirali (Karnataka): 6; and Mangaluru (Karnataka) and Kozhikode (Kerala): 5 each.

Elsewhere, random areas in Rajasthan and Gujarat received very heavy to extremely heavy rainfall as a remnant low-pressure area left behind by erstwhile very severe cyclone ‘Vayu’ lingered over the region.

Potent ‘Vayu’ remnant

On Wednesday, the ‘low’ was located over North East Madhya Pradesh and adjoining South Uttar Pradesh. Cyclone ‘Vayu’ may have upset the progress of the monsoon, but its remnant seems to be making amends over North-West India.

Main stations here receiving the unexpected bounty from the skies (in cm) overnight on Wednesday included Pratapgarh: 28; Chittorgarh: 20; Udaipur: 14; Bundi and Kota: 5 each (all Rajasthan) and Ahmedabad (Gujarat): 5. Meanwhile, arrival of a western disturbance over the hills of North-West India from Sunday bristles with the prospects of a productive interaction with the incoming ‘low’ from the Bay. This, too, could bring heavy to very heavy rain over parts of Central and North-West India, if previous instances of an itinerant western disturbance running into a ‘low’ drifting in from the Bay are any indication.

Heavy rain forecast

On Friday, heavy rain is forecast by the India Met Department over Tamil Nadu, Puducherry, Kerala, Coastal and South Interior Karnataka, Coastal Andhra Pradesh, Konkan and Goa, Rayalseema, Telangana, Chhattisgarh, plains of Bengal and Odisha.

On Saturday, heavy to very heavy rainfall is seen over Coastal Karnataka and Kerala, while it would be heavy over Interior Karnataka, Tamil Nadu, Puducherry, Coastal Andhra Pradesh, Telangana, Rayalaseema, Konkan and Goa, South Madhya Maharashtra, Chhattisgarh, and Odisha.
