The month of June ended with 5 percent deficient Pan India rains which falls under the normal range only. Thereafter, rainfall remained on the deficient side on the first day of July as well due to which the rainfall deficiency mounted to 7 percent and the same situation has been prevailing for the past four days which means normal rains have been occurring for quite some time now.
However, Monsoon surge has not been giving even and well distributed rains. Generally, Monsoon is a very stable feature which does follow a set of norms due to which predictions are made. However, this time Monsoon has been behaving in a different manner which has been causing unevenly distributed rains.

Here are three instances which show the truant behaviour of Monsoon:
Firstly, whenever the Monsoon trough shifts along the foothills, north of its normal position, Northeast India sees heavy rains. In fact, particularly the states of Assam, Meghalaya and Arunachal Pradesh see extremely heavy rainfall as well.
However, this time, such a situation has not occurred and despite of the trough being over the foothills, both East and Northeast India are 20 percent rain deficient. Such deficiency clearly shows that Arunachal Pradesh, Assam and Meghalaya have not bee responding to the persisting situation well.
Secondly, the West Coast performs along the full stretch with very little variation. This time, the complete region has not been recording rains as its stipulated pattern leaving gaps of poor rains in between. In fact, the entire sub division of Kerala which happens to be one of the rainiest pockets has been rain deficient this time.
The situation is precariously leaving hollow pockets with some inexplicable features.
For instance, both South and North of Mumbai saw three digit rains about a day before but Mumbai saw very little rains. Moreover, the city did see over 250 mm rains before that but not on that particular day.
Thirdly, Monsoon covered the entire country about 15 days before it usually does. Normally, Uttarakhand is the rainiest pocket in the hills of North India and Jammu and Kashmir sees the least amount of rains.
Moreover, due to the shift of the Monsoon trough, the state of Uttarakhand could have seen very heavy rains but that was not the case this time. In fact, it was Jammu and Kashmir which saw heavy rains to the extent wherein flooding was also observed in some parts of the valley. Meanwhile, Uttarakhand saw very little rains.
Until now, Jammu and Kashmir is seeing excess rains of 49 percent, Himachal Pradesh at 30 percent and Uttarakhand at 4 percent. Under such conditions, reversal in pattern has been seen.
However, the good news is that a trail of systems is likely in the Bay of Bengal. One of these systems has already appeared bringing in Monsoon over the entire country.
Another system is expected to occur soon which will bring rains across many parts of the country. During the next ten days, momentum will remain, and rains will occur over many parts of the country.
