Rains Lessen Over Northeast India, Flood Situation to Improve: Fresh Spell Next Week
Jun 5, 2025, 2:36 PM | Skymet Weather Team
The spread and intensity of rains have diminished substantially over Northeast India over the last 48 hours. Many stations have reported single-digit rainfall in the past 24 hours, and these locations include Dibrugarh, Tezpur, Silchar, Golaghat, Golpara, Dhubri, Kohima, Imphal, Aijwal, Agartala, and Pasighat.
Some stations have reported double-digit rainfall, but heavy downpour has eluded the entire region. Following the cessation of incessant rains, the flood situation is likely to improve over the next couple of days. Relief and rescue work can be speeded up , both by surface and air.
The flood situation over the northeastern parts is a very complex problem. The Assam Valley is surrounded by the mountains of Arunachal Pradesh, Nagaland, Manipur, and Meghalaya. The mighty Brahmaputra flows through and through the state of Assam from Tinsukia-Dibrugarh to Dispur-Guwahati before heading for Bangladesh. The entire terrain is heterogeneous. Rainfall catchment areas for the Brahmaputra are spread across Arunachal Pradesh, Tibet, and Bhutan.

There are a large number of tributaries, major river networks, and water bodies feeding the ferocious Brahmaputra at various points. More than the rains over the state of Assam, a large volume of water from all these sources gets deposited in this river flowing from Upper Assam to the capital city of the state. The problem gets aggravated as the water bodies keep responding violently and unabatedly, even much after the rains recede from the state. That is exactly what the situation is prevailing right now. Many of the auxiliary rivers along with the Brahmaputra continue to flow above the danger level. Huge stocks of water breaching the banks of the rivers and inundating roads, fields, and villages have to retreat back to the river, and it is a time-consuming process.
Recession of floodwaters is as slow a process as it is difficult to perceive. And the irony of the northeastern region is that the heavy rains during monsoon keep revisiting some parts or the other without adequate pause in between. More or less, it becomes a relay race, handing over the baton from one to the next.
The ‘break’ in the interminable rains, as of now, is temporary. Moderate to heavy rains are likely to resume yet again sometime next week. A low-pressure area is likely to form over the Bay of Bengal. As a precursor to the system, a cyclonic circulation will appear over that area from 10th June onwards. This situation becomes ideal for pumping moisture-laden southerly winds from the Bay to the Assam Valley and the mountainous region around. A fresh bout of rains may last between the 10th and 15th of June. The wet spell may not be as heavy as the last one, but still, utmost caution needs to be exercised .
