The country recorded a 41% rainfall deficit between June 4 and June 18. According to the India Meteorological Department (IMD), the country received only 42.6 mm of rain during this period, compared to the normal 72.2 mm. The IMD attributed this decrease to a “lack of favorable weather conditions.”

Monsoon: The country has recorded a 41 percent rainfall deficit between June 4 and June 18 due to the southwest monsoon being stalled in South Maharashtra. According to the India Meteorological Department (IMD), the country received only 42.6 mm of rainfall during this period as against the normal 72.2 mm. According to the IMD’s region-wise data, Central India has recorded a rainfall deficit of 67%, East and Northeast India 42%, Southern Peninsula 22% and Northwest India 6%.
The Meteorological Department said on Thursday that “lack of favourable weather conditions on a large scale” is the main reason why the southwest monsoon has not been able to advance into the rest of Maharashtra in the last few days.
There are a total of 5 major reasons behind the delay in the northward advance of the monsoon :

The Meteorological Department said on Thursday that “lack of favourable weather conditions on a large scale” is the main reason why the southwest monsoon has not been able to advance into the rest of Maharashtra in the last few days.
There are a total of 5 major reasons behind the delay in the northward advance of the monsoon :
The first reason is that the current monsoon flow is not being supported by strong “surges,” or strong and steady winds from the Arabian Sea. According to the Meteorological Department, “Such strong winds are typically responsible for increasing moisture and producing widespread rainfall, which helps advance the monsoon.”
Another reason is that the monsoon-related low-level southwesterly winds in the Arabian Sea have weakened, reducing the flow of moisture to coastal and interior Maharashtra.
A third factor is the weakening of the cross-equatorial flow in the western Indian Ocean and the Arabian Sea, which is considered the main moisture source for the southwest monsoon. According to the IMD, the weakening of this flow has also affected monsoon activity.
A fourth reason is that there are currently no strong weather systems in the Arabian Sea and Bay of Bengal, such as a low-pressure area, a cyclonic circulation, or an active offshore trough along the west coast. These systems normally help advance the monsoon, but they are currently lacking.
The final factor is a weakening of the Madden-Julian Oscillation (MJO). This is a dynamic system of wind, clouds, and pressure that circulates around the equator, bringing rain. When it’s active, more clouds form over southern India, which, along with monsoon winds, move northward, bringing more rain. However, it’s currently weak.
According to IMD, due to this, rainfall is likely to remain limited and only sporadic in most parts of Maharashtra for the next 4-5 days.
Kharif crops will be affected by El Nino
The slow northward movement of the southwest monsoon and the recent El Nino conditions in the tropical Pacific Ocean, which have led to deficient rainfall in India, could have serious consequences for Kharif crops, which require timely rainfall for their growth.
Shivraj Singh Chouhan gave instructions to the officials
In light of this, on Tuesday, Union Agriculture Minister Shivraj Singh Chouhan directed that districts be identified where there is a possibility of low or uneven rainfall. He also directed states to develop crop-specific contingency plans to mitigate potential losses.
The Minister stressed that special attention should be given to water conservation, moisture management, inter-cropping and alternative cropping patterns.
Chauhan directed that a separate and practical strategy should be made for every vulnerable district so that farmers do not face any problems during the Kharif season.
