Northeast India is one of the rainiest pockets of the country during Southwest Monsoon season. However, this year, Monsoon has remained mostly normal to subdued over most parts of Northeast India.
On the last day also, vigorous to active Monsoon conditions were observed by a few pockets of Northeast India. Within the span of 24 hours, from 08:30 am on Tuesday, Majbat recorded extremely heavy rains to the tune of 129 mm, Silchar 25 mm, Barapani 24 mm, Imphal 17 mm, Kohima 13 mm, Chaparmukh 12 mm, Pasighat 7 mm, Golaghat 7 mm, Shillong 4 mm, Jorhat 4 mm, Guwahati 4 mm, North Lakhimpur 3 mm and Goalpara recorded 2 mm of rains.
However, remaining subdued in most parts in the month of July, the rains over Northeast India increased last week. The reason for these rains can be associated with a cyclonic circulation that was persisting over Assam. Moreover, a trough is also extending from the central parts of Uttar Pradesh to Assam.

In the wake of this, light to moderate with one or two heavy spells occurred over Assam, Arunachal Pradesh, and Nagaland for the last few days. The remaining parts of the region also received light to moderate rains.
As of now, the eastern end of the axis of Monsoon trough is expected to remain over Northeast India along the foothills of Assam and Arunachal Pradesh. Moreover, the cyclonic circulation is also seen at mid-levels over the northwest Bay of Bengal.
Thus, we expect light to moderate with one or two heavy spells to continue for the next 2-3 days. However, in spite of these rains, most parts of the region have remained rain deficient and is not able to cope up with the normal range.
As on July 31, Arunachal Pradesh is rain deficient by 37%, Assam & Meghalaya are 33% rain deficient, meanwhile, the NMMT (Nagaland, Manipur, Mizoram and Tripura) region is rain deficit by 23%.
