Active monsoon conditions are now shifting closer to the foothills of Himalayas, an India Meteorological Department (IMD) outlook said on Thursday.
This would lead to heavy to very heavy rainfall along the foothills of the Himalayas and the Northeastern States.
HEAVY RAIN
An IMD warning valid for the next two days said that heavy to very heavy rains may break out over sub-Himalayan West Bengal, Sikkim, Assam, Meghalaya and Arunachal Pradesh during the next two days.
Heavy rainfall has been indicated also for Nagaland, Manipur, Mizoram, Tripura, Bihar and east Uttar Pradesh during this period.
This is likely to trigger another round of massive flooding of rivers of the region and mudslides and avalanches in the traditionally vulnerable stretches.
The monsoon usually migrates fully to the east and northeast after it runs all over the country through June and early July.
NEXT WAVE
Parts of southeast India, especially along the coast, too benefit from the rain heads venturing in from the east and northeast.
The monsoon would not become active over the rest of the country (northwest, central and peninsula) unless the Bay of Bengal conjures up the next rain wave.
And this can take days together. Latest forecasts suggest that these rains would materialise by July 21 over central India.
On Thursday, the rains over Rajasthan dried up and some of the residual moisture is getting fanned to the east (Punjab, Haryana, Delhi and Uttar Pradesh).
In its two-day outlook, the IMD said that thundershowers are likely over Haryana, Delhi, West Uttar Pradesh and Rajasthan on Friday.
DRY IN PENINSULA
Rains have been forecast also over Punjab, Chhattisgarh, east Madhya Pradesh, Vidarbha and east Gujarat.
Extended outlook valid until Thursday next saw rains over the west coast, the Northeastern States, western Himalayan region, the Gangetic plains and the rest east India and at a few places over central India.
Subdued rainfall activity has been forecast for interior peninsular India.
