The northeastern states of India that is Assam, Arunachal Pradesh, Meghalaya, Nagaland, Manipur, Mizoram and Tripura are currently rain deficient. Although on and off rains were going on over parts of Northeast India, particularly over Assam and Arunachal Pradesh, but the intensity and spread remained on the lower side over most of the states. Thus, it failed to bring down the rain deficiency.
According to Skymet Weather, since the last few days, an Anti-Cyclone has been persisting over North Bay of Bengal, due to which moisture feed remained restricted over Northeast India.
Now a Cyclonic Circulation has formed over Assam and adjoining area. Along with this, the Anti-Cyclone is also moving away. Therefore, the moisture feed will increase over Northeast India in the form of southwesterly humid winds.
As a result, rain and thundershowers will now increase over all the states of Northeast India and these on and off weather activities will continue for at least one week. Isolated heavy spells also cannot be ruled out during this time.
We expect lightning strikes accompanied with hailstorm activity in few districts of Meghalaya, Nagaland, Manipur, Mizoram and Tripura. Thus, we can say that a rainy week is ahead for Northeast India. In the wake of these rains, by the end of March, we expect rain deficiency of the northeastern states to reduce to some extent.
