Since last 6 to 8 days, heavy to very heavy rains have been lashing almost the entire Northeast India. So much so that most districts of the northeastern states of the country even submerged under flooding rain water.
In the last 24 hours as well, few districts of Northeast India witnessed record-breaking rains. Within a span of 24 hours from 08:30 am on Tuesday, Silchar in Assam recorded hefty showers of 108 mm which is the highest in a decade. During the similar time frame, Pasighat in Arunachal Pradesh observed 161 mm of rainfall, which is the highest rains in last 7 years while second highest in a decade.
With these, both the districts even surpassed their monthly mean by a huge difference as well. The monthly average rainfall of Silchar stands at 258.1 and counting on yesterday’s downpour, it has already recorded 508.2 mm of rains in April so far. Similarly, the monthly average for Pasighat is 259.5 and it has already recorded 438.4 mm of showers so far in the month.
The reason for this heavy downpour over the region was the cyclonic circulations that were persisting over different regions of the northeastern states. Initially, a cyclonic circulation was over Assam and Meghalaya and during the last 48 hours, it was seen over the NMMT (Nagaland, Manipur, Mizoram and Tripura) region.
As per Skymet Weather, due to these weather systems, humid winds from the Bay of Bengal have increased the moisture leading to hefty showers at many places over the region. Moreover, due to these torrential rains, many low-lying areas of Tripura such as Agartala even inundated under rain water.
Many districts of Bangladesh has also seen flooding rains. However, the good part is that the situation is not very severe over both Bangladesh and Northeast India.
Fortunately, the cyclonic circulation has now faded away and at present, a trough is running from East Bihar to Assam which is likely to give light to moderate rains at any places over Assam, Meghalaya and Arunachal Pradesh for another 24 hours. However, there will be a significant decrease in the rain intensity over the NMMT region which will result in improving the water logging conditions.
The intensity of these pre-Monsoon showers will be very less for next 4-5 days which will help in further improving the situation.
