Normally during Monsoon, the Northeast region of India records heavy to extremely heavy rainfall. However this year, the subdivision of Assam and Meghalaya was rain deficient by 30%, whereas the region comprising Nagaland, Mizoram, Manipur and Tripura was rain deficit by 17 %. It is only Arunachal Pradesh where rain deficiency was 4% which falls under the normal rain category.
In fact, since the beginning of October, the entire Northeast India has received scanty rainfall. The reason for these rains can be credited to the northwesterly winds which have made sure that the rainfall activity continues over East and Northeast states of India.
In a span of 24-48 hours, fairly widespread rains have been witnessed over most parts of Northeast India. This rainfall spell is expected to last for another 2-3 days. During this period, while the intensity of rain will increase over West Assam and Meghalaya, scattered showers will continue over Nagaland, Manipur, Mizoram and Tripura region. In fact, a few areas may even witness a few heavy spells of rains during the aforementioned period.
These showers can be attributed to the cyclonic circulation which is seen over Northwest Bay of Bengal, bringing moist winds to the northeastern states.
