It has already covered about 40% of total geographical area of the country
After a sluggish start, the south-west monsoon is on the upswing, covering newer areas by the hour.
Director-General of India, Meteorological Department, L.S. Rathore told The Hindu on Sunday that the system had already covered about 40 per cent of the total geographical area of the country and the coverage could go up to at least 50 per cent by Monday evening.
The rapid progress means the deficiency of rainfall at the all-India level has come down to 36 from 42 per cent on Wednesday [June 13]. Central India is the biggest beneficiary, as the system has been mainly active in the region: the deficiency in the region has come down to 49 per cent from a whopping 65 per cent in the past four days.
In the southern peninsula, the deficiency has dropped from 57 to 51 per cent and in the east and the northeast, it has gone down from 17 to 12 per cent over the same period.
In the northwest region, where the monsoon is yet to register its presence, however, the deficiency has gone up from 52 to 61 per cent.
“The situation should improve in the north-west region also very soon. The way the system is marching forward, it should not be long before it reaches this region too,” Dr. Rathore said.
Asked about Delhi, where the normal date for the monsoon to set in was June 29, he said conditions were getting favourable for the system to reach the city. He, however, declined to comment on when it would happen.
“Please wait for some days. Conditions are becoming ripe. The moisture level in the area is slowly going up and the western disturbance over north Pakistan and neighbourhood is persisting.”
Noting that forecasts could be made with a certain level of confidence for only three days and that there could be an “outlook” at the most for a further period of four days, he said: “As of now, there does not seem to be a possibility for the system to reach Delhi during this time frame. Let us wait for some more time.”
Over the past 24 hours, the monsoon has advanced into the remaining parts of Konkan, interior Karnataka and Andhra Pradesh, and has covered some more parts of West Bengal and Sikkim, most parts of interior Maharashtra and some parts of south Gujarat, Chhattisgarh and Orissa.
It is expected to cover the remaining parts of Maharashtra, Orissa, West Bengal and Sikkim, and some more parts of Gujarat, and Chhattisgarh, besides making its way into some parts of Madhya Pradesh, Jharkhand and Bihar over the next three days.
According to the IMD’s bulletin issued on Sunday evening, a low pressure area may develop in the Bay of Bengal during the next 48 hours under the influence of an upper air cyclonic circulation over its northern part.
