Low-Pressure Areas and Depressions are the major Monsoon drivers in India. The axis of Monsoon Trough does not reach Bay of Bengal in the absence of these Monsoon drivers. When the Trough moves along the foothills, Break Monsoon conditions fall into place. At least three to four Monsoon Lows are very common in Monsoon in India.
Unlike other parts of the country where Monsoon Lows directly impacts the weather, Northeast India remains peculiar to this pattern. In this region, the weather improves as soon as a Low-Pressure Area forms in the Bay and Monsoon activities subdues and picks up only when the system moves sufficiently inside the landmass.
Easterly and Southeasterly winds bring in light rainfall over the Northeast states. However, westerly and southwesterly winds are indicative of bad weather and heavy rains.
At present, a series of Low-Pressure Areas are likely in the Bay of Bengal in the upcoming few days. One Low Pressure Area is already affecting the Bay of Bengal at present. This is the third Low in the Monsoon season so far. Another Low is likely over the Bay on August 3 while it will be followed immediately by yet another Low on August 5.
This is indicative of fluctuating weather in Northeast India in the next few days.
At present, Northeast India is running rain deficient just by 10%. Also, multiple Northeastern states are running rain Normal.
Northeast India experiences a four-month long Monsoon season. Northeast India is also one of the rainiest pockets in India which contributes more than 30% to the pan-India Monsoon rains.
