The monsoon deficit has narrowed to 33 per cent from 47 per cent in four days due to heavy rainfall in Gujarat and Rajasthan. But as much as 66 per cent of the land in the country has below-normal rainfall so far as the monsoon has been stalled since June 11.
The south-west monsoon has further advanced into parts of Karnataka, Andhra Pradesh, some parts of Gangetic West Bengal and Jharkhand, some more parts of Bihar, and the remaining parts of sub-Himalayan West Bengal and Sikkim on June 19,” the India Meteorological Department said.
“In a week from now, the central region, including Madhya Pradesh, will also get monsoon rains, and by the end of the month, many parts of the country will be covered,” said DS Pai, senior scientist and former head of the long-range forecast team at IMD. He said this is the second pulse in the monsoon system, and the advancement may be smooth henceforth.
The pan-India rainfall deficit in the current monsoon season (June-September), which was 47 per cent of the long-period average (LPA) until June 16, has narrowed to 33 per cent of the LPA until June 19. The monsoon onset was delayed by a week this year as it reached Kerala on June 8.
Rajasthan and Gujarat have reported surplus rain because of Cyclone Biparjoy. Another region that has received heavy rainfall is the union territory of Andaman and Nicobar, where monsoon precipitation is 52 per cent higher. Punjab, Assam, Meghalaya, Sikkim, and Ladakh are the other States and union territories with positive rainfall.
The depression over central parts of south Rajasthan and neighborhoods due to Cyclone Biparjoy has weakened into a well-marked low pressure area over central parts of north-east Rajasthan and neighborhoods on Monday morning. As it is likely to move east and north-east, IMD has predicted light to moderate rainfall at most places over East Rajasthan on June 19 and isolated heavy to very heavy rainfall on June 20–21. Rainfall has also been forecast over north-west and north-east Madhya Pradesh between June 19 and 21.
