Heavy Rainfall Likely Over Assam, Arunachal and Meghalaya

Far eastern parts of Assam and Arunachal Pradesh have received scattered heavy rainfall in the past 24 hours. Dibrugarh, on the far eastern corner, had a deluge of 188 mm and North Lakhimpur received 41 mm of rainfall. 

Pasighat in Arunachal and Cherrapunji in Meghalaya recorded rainfall of 80mm and 54 mm, respectively. Heavy rainfall is likely at many places over Assam, Arunachal and Meghalaya over the next 4-5 days.

A cyclonic circulation is marked over Northeast Assam and the adjoining region. An east-west trough is visibly marked across the Assam Valley. Southwesterly winds from the Bay of Bengal are feeding moisture over the region, across Bangladesh.

The weather activity will continue over Northeast India in general, but intense pockets are likely over Assam, Arunachal Pradesh and Meghalaya.

Upper Assam and Eastern Arunachal Pradesh will have moderate to heavy rainfall between 24th and 26th April. 

The places at risk will include Dibrugarh, Tinsukia, Lakhimpur, Digboi, Dheemaji and Sivasagar.

The northeastern corner of Arunachal Pradesh will include Pasighat, Teju, Anjaw, Dibang Valley and the Siang region. 

The intense weather activity will shift to lower Assam and Meghalaya on 27th and 28th April. The vulnerable places in Assam will be Barpeta, Golpara, Nalbari, Kokrajhar, Dhubri and Kamrup.  

Over Meghalaya, in addition to the Garo and Khasi hills, the capital city, Shillong, Barapani and Tura will also be at risk of inclement weather activity.

The downscaled weather activity will continue over the region during the first week of May as well. Most of the thunderstorms are accompanied by lightning and heavy downpours in the late evening and night hours. 

A break in the weather activity is expected in the forenoon and afternoon hours. Prolonged spells of incessant heavy rains may trigger some landslides, obstructing roads and highways, more so for Meghalaya and the farther region of Arunachal Pradesh.
