Rainfalls were 44 per cent above average during the week through September 19, and monsoon would stay in the northern India for another one week, the Indian Meteorological Department (IMD) said.

During the previous week, monsoon rains were 21 per cent above average. Analysts are of the view that a late revival of monsoon would provide a boost to the yield of summer-planted crops like rice, corn, soybeans and cane. But the late revival will not completely be able to offset the damage. Moreover, rainfall remained 5 per cent short of average since the start of the season.

Monsoon reached Rajasthan on 5th of July, but picked up impetus from 15th of August.

The IMD had expected monsoon to retract from the northern India by now, but the officials of the department now believes that it would take one more week to retreat.

Speaking on the topic, a Met official said, "Earlier, we expected the withdrawal of monsoon to start from September 20. However, the ongoing pattern suggests that it will be active in state for at least another week."

The official added that the prolonged stay of monsoon could be attributed to strong disturbances from Bay of Bengal and Arabian Sea.

Monsoon rainfalls are vital for around 55 per cent of India's farmland which has no irrigation facilities. The farm sector accounts for roughly 15 per cent of India's $2-trillion economy.
