New Delhi: Although the withdrawal of the southwest monsoon has already started, many parts of India, except north India, are still getting rainfall. According to an India Meteorological Department (IMD ) forecast, above-normal rainfall will continue over northeast and adjoining east India until September end or the first week of October.

Also, increased rainfall is expected over the northern peninsula and adjoining central India during the next week. An increase in rainfall over southern peninsular India will begin at the end of September.

“This incremental rainfall activity from 22nd September will help the standing crops. It will also benefit the succeeding rabi crops,” said N. Chattopadhyay, deputy director general at the agricultural meteorology division of IMD.

India has so far received 5% less rainfall than the long period average (LPA) since the onset of the monsoon in June. Currently a low pressure is formed over Coastal Andhra Pradesh and neighbourhood. Another is being formed over central Bay of Bengal. These low pressures will cause a downpour that would narrow down the current deficit of 5%.

IMD director general K.J. Ramesh told PTI, “The monsoon will be normal this year.”

Central India has so far recorded 3% more rainfall than the 50-year average. While northwest and south peninsula and east and northeast India have recorded a deficit of 4% ,10% and 13%, respectively. The deficit areas of the country include Kerala, Coastal Karnataka, Gujarat, Dadra and Nagar Haveli, Daman, Punjab, Haryana, Chandigarh, Delhi, Himachal Pradesh, Assam and Meghalaya.

Usually normal withdrawal of monsoon from the northwestern parts of Rajasthan is around 1st September, but this time it was delayed by 15 days. Kutch, where monsoon withdraws by 15 September, will show delayed withdrawal this season due to humidity from south westerly winds from the Arabian Sea. So far, the withdrawal line of monsoon is over Anupgarh, Bikaner and Jaisalmer in Rajasthan.

Mahesh Palawat, chief meteorologist at Skymet, a private weather service, said, “The complete withdrawal of monsoon from India will take place by first week of October against the normal of 1st October.”

According to the first advance estimates of crop production released by the agriculture ministry on Thursday , India’s rain-fed kharif harvest is the highest ever in history.

India’s kharif foodgrain production is estimated at 135 million tonnes in 2016-17, 9% higher than the year before, when a crippling drought affected several states across the country.
