A minor revival in the monsoon is expected to bring the rains afresh into East and adjoining Central India, parts of the South, the West Coast and East Coast next week.
The causative upper air cyclonic circulation has shifted to base to North Bay of Bengal; its graduation to a low-pressure area also is expected in good time.
The ‘low’ is likely to get embedded into the land-based trough linking North-West India with East-Central Bay as observed on Thursday.
According to a four-day India Met Department outlook valid from Sunday, rain or thundershowers would occur at most places over North-Eastern States, Sub-Himalayan West Bengal and Sikkim.
Alongside, a wet spell would be initiated over the West Coast with many places expected to slip under it. A few places along the East Coast and the rest of Peninsular India too would benefit.
Increase in rain Importantly, the Met has predicted an increase in rain activity over western Himalayan region and Uttar Pradesh.
Thundershowers have been forecast at isolated places over rest of the country outside Rajasthan where weather may be mainly dry, it said.
According to the US Climate Prediction Centre, the week from July 3-9 will witness reasonably good rainfall all across the eastern half of the country.
This will cover east Uttar Pradesh, whole of Bihar, Jharkhand, Chhattisgarh, West Bengal, Odisha, coastal Andhra Pradesh, Vidarbha and the entire North-East.
West coast Fresh spurt of rains will enter most of the West Coast, with rains expected to be particularly heavy over Konkan, Goa, coastal Karnataka and north Kerala.
But the rest of Central India, West and North-West India will continue to go without any major rain.
Meanwhile, on Thursday, a combination of atmospheric features involving a fresh western disturbance and feeble easterly winds triggered thunderstorms extensively over North, North-West and East India.
Thunderstorms rolled out variously across Jammu and Kashmir, Himachal Pradesh, Haryana, Delhi, Punjab, east Madhya Pradesh, coastal Andhra Pradesh, Uttarakhand, north Rajasthan, east Uttar Pradesh, Bihar, Chhattisgarh, Jharkhand and Vidarbha.
The Met has forecast isolated heavy to very heavy rainfall over Assam, Meghalaya, Gangetic West Bengal, Odisha and north Coastal Andhra Pradesh for next two days.
