Monsoon Deficit @11%

The national rainfall deficit has now fallen to 11%. The monsoon, however, remains active over central India and there's no sign yet of its withdrawal from the country . The withdrawal normally begins from Rajasthan around September 1 and is completed by the middle of the month.
“Monsoon remains very much active in the country and we see no signs of withdrawal beginning in the next five days,“ B P Yadav, director, India Meteorological Department said. Meanwhile, after sharp gains in the past 10 days, the monsoon deficit in the country has narrowed down to 11%. The latest monsoon revival started around August 29, when the shortfall stood at 18% and the country seemed headed for a drought year. The revival began in central India, coming after three weeks of subdued rains in large swathes of the country. Around September 2, a confluence of three rain-bearing systems over Punjab drew copious amounts of moisture into north India in a five-day spell that wreaked havoc in J&K.
The late monsoon surge over the grain bowl belt of Punjab, Haryana and west Uttar Pradesh may not help the standing crops, but it quickly reduced the rain shortfall in the parched region. The seasonal deficit in northwest India dropped from 33% on September 3 to 20% five days later.
The rain shortfall in Punjab and Haryana has reduced to 48% and 54%, respectively, from a peak of 65% at the beginning of the month. The change was most dramatic in J&K. The state had a deficit of 32% on September 3 which in a span of five days was transformed to 18% excess rains — a change of 50 percentage points. In Delhi, the shortfall stands at 39%.
With the factors responsible for the deluge — an interaction of air masses coming from Arabian Sea and Bay of Bengal with a western disturbance — having passed, most parts of north India are unlikely to get heavy showers in the next three-four days.
