Assam, Meghalaya and Arunachal Pradesh to witness heavy downpours August 24-27 as northeast India braces for wet week | The Weather Channel – Articles de The Weather Channel
Monday 23 August: Parts of northeast India will experience increased rainfall activity over the coming week as heavy downpours are forecast in several states in the region.
Fairly widespread to widespread rains with isolated heavy falls are most likely to continue over northeast India through Tuesday August 24, according to the Indian Meteorological Department (IMD).
Subsequently, the intensity of rainfall is expected to increase, with very heavy isolated falls expected to hit Arunachal Pradesh, Assam and Meghalaya between Tuesday and Friday August 24-27.
Separately, extremely violent isolated falls could also bombard Assam and Meghalaya on Wednesday, August 25.
In view of these predictions, all of the aforementioned states have been placed on orange alert for this forecast period. The alert urges residents to “prepare” for difficult conditions. However, the advisory level can be further improved if the weather conditions intensify.
According to The Weather Channel’s weather team, total precipitation of more than 250mm over 5 days is expected in these states. Rainfall activity in the region will be at its maximum from Tuesday to Thursday.
Meanwhile, according to the latest update from the Central Water Commission (CWC), Assam state will be particularly vulnerable to flooding.
Due to notable rainfall activity over the past 4-5 days, the main Brahmaputra River is already flowing in above normal flood situations to severe flood situations in Goalpara, Dhubri, Dibrugarh, Sonitpur and Jorhat of Assam.
In addition, the tributaries of the Brahmaputra, viz. Subansiri River in Lakhimpur, Beki River in Barpeta, Jia-Bharali River in Sonitpur, Sankosh River in Dhubri and Desang River in Sibsagar (Assam); as well as the Siang River in eastern Siang of Arunachal Pradesh, all flow from above normal flooding situations to severe flooding situations.
With more intense downpours on the horizon for the week, the flood situation in these areas could worsen, affecting the livelihoods of local residents.
With regard to seasonal precipitation over the region, the northeastern states have received normal to below average precipitation since the start of the monsoon season.
Between June 1 and August 22, the Meghalaya (1833.8 mm) and the Tripura (897.8 mm) recorded “normal” rains compared to their respective long-term averages for this period, while the Arunachal (947mm), Assam (877.7mm), Mizoram (863.3mm) and Nagaland (646.5mm) all experienced “deficit” rainfall.
