The average rainfall during the Monsoon season for Sub-Himalayan West Bengal and Sikkim is around 2006 mm. It is more than the seasonal rainfall of Assam, Meghalaya and Arunachal Pradesh, wherein the Monsoon average rainfall for these pockets is less than 1800 mm.

At the time of Monsoon, this pocket has a different pattern that is during Active Monsoon, it rains the least over here. However, during Break Monsoon, this pocket gets drenched like anything and this is what we are witnessing at present.

For the next four days, torrential rains would continue over the region and these rains will only subside when any system would build up in the Bay of Bengal.
