Break of monsoons is the break in the monsoonal rainfall. It typically happens in the month of August

During the Monsoon season, there are periods when the Monsoon trough (at Surface Level) shifts closer to the foothills of Himalayas, which leads to sharp decrease in rainfall over most parts of the country. ... Such a synoptic situation is known as the 'break Monsoon' period. 
At times we have a "Partial break Monsoon" , when only one end of the Monsoon trough moves close to the Himalayas.

In the current situation, the Western end of the trough has moved to the foothills of the Himalayas the BB-7 and Western Disturbance interacted recently in the Northern States. 
The Eastern end has also moved Northwards as a result of BB-9, now located over Jharkhand.

The pressure gradient shrinks (from maximum gradient) along the West Coast.


Next 3 days, Tuesday, Wednesday and Thursday:
Hence, heavy rains expected in Northern parts of M.P. and U.P. 
Heavy rains likely in South Interior Karnatak ,Rayalseema and  North T.N.

Subdued rains in peninsula, Central and Western India and Kokan Coast.
Rains reduce in North West India.

Next 3 days, Tuesday, Wednesday and Thursday:

Mumbai: Partly cloudy with sunny spells. Few showers in different parts of city...Rain 5-10 mms.
Pune: Light rains in different regions and parts of city. Days expected to get warmer, around 30c. 

Revival of meaningful rains in both the above places not before weekend.

Parts of south and Madhya Maharashtra had heavy and flooding rains in the first week of August. This has improved the overall State Monsoon situation to +32%, while Madhya Maharashtra is +70%. 
Overall All India Rainfall is now >1% Plus.

New Delhi and Surroundings: Subdued rains and Not much of rainfall. In fact heating upto 39/40c. 


This is a personal note, to just inform that there was less updating of Vagaries last few days as I was indisposed, a severe Vertigo Attack. Stable Now. Writing this as I consider all my Readers as a family. Vagarians' Family.

Posted Wednesday evening :

BB 8 tracks over M. P. Bringing good rainfall. 
East MP 5-16 vms, West M. P up to 12 cms and a good 4-16 cms in Vidharbh. 
From the gradient of the system, Delhi Airport recieved 26 mms and S'jung 10 mms.

However, the system was not strong enough to garner strong SW winds over North Konkan. ( BB 8 is already a well marked low). 
As a result the UAC in the west coast off shore trough fizzled out overnight and the trough ran from Goa to kerala. 
Mumbai as a result of this did not get the anticipated rains. 
Mumbai may still hold a chance of a small revival upto next 18 hrs.
