Heavy Rains Over Northeast India To Ease Out Soon: Flood Recovery May Take Time

Northeast India has been hit with flash floods and landslides following excessive heavy rains, more so in the catchment areas. Unrelenting rains wreaked havoc last Thursday-Friday, with Meghalaya and Assam experiencing incessant heavy rains.

Heavy rains continued over Assam & Meghalaya and Nagaland, Manipur, Mizoram, and Tripura on 31st May as well, albeit with little respite. Fairly widespread rains will continue in the next 24-36 hours and start easing out thereafter. Most of the weather activity will take place in the late evening and night hours. Better weather conditions can be expected in the forenoon and afternoon hours.
The rains were initiated with the depression over Bangladesh and adjoining parts last week. The main weather system, though it moved away by last Friday, had a remnant effect that continued even thereafter. This is a very normal pattern over the northeastern parts.
Under the influence of the early onset of monsoon, coupled with the passage of a depression, a deluge resulted over many parts of the region. The monsoon trough over the region remains close to the foothills of Arunachal Pradesh, leading to heavy rainfall in some pockets over Assam, Meghalaya, Mizoram, and Tripura.
As it is, when the monsoon current goes weak over the country, the northeast region becomes more susceptible to heavy rainfall in some areas. As the southwesterly winds from the Bay of Bengal to Northeast India, across Gangetic West Bengal and Bangladesh, slow down, the weather conditions will improve significantly after 24-36 hours. However, the complexity of the terrain does not permit the river network to get softened. Water bodies keep responding even after the rains ease out. 10 major rivers of the region are flowing above the danger level. The tributaries of the river Brahmaputra are all swollen and feeding the mightiest river, leading to a grim flood situation. That will take some time to improve. However, weather conditions will become suitable for carrying out relief operations.
Rains are likely to become less destructive and ease out over most parts in the next 24-36 hours. Even during this period, the weather activity will mostly remain confined to the late evening and night hours. Typical normal light to moderate valley rains are likely from 03rd June onwards. Major relief for the region and cessation of weather activity get underway only with the formation of a monsoon low or depression over the Bay of Bengal. That situation is likely to happen, but not before 10th June. Revival of monsoon for the country will also coincide with that event.
