Monsoon Rainfall Deficit hits 43%, Might improve by next week
New Delhi: The overall rainfall deficiency in the first half of June has reached up to 43 per cent and it might worsen the drought-like situation prevailing in many states, informed Indian Meteorological Department (IMD).
While this is partly because the monsoon arrived after a delay of seven days, on June 8, and then because of severe cyclonic storm Vayu that started developing on June 11. Cyclone Vayu disturbed the monsoon flow and affected its normal advancement, they said.
According to IMD’s bulletin on Monday, cyclone Vayu has moved north-eastwards and weakened into a deep depression. The IMD scientists expect monsoon advancement to pick up again in 3-4 days.
“Such a cyclonic storm disturbs the circulation pattern or flow of the monsoon. The storm has weakened now and we are expecting advancement to revive in the next 4-5 days,” Sathi Devi said. Most parts of Karnataka, Andhra Pradesh, Telangana and Odisha haven’t received any monsoon yet, shows IMD’s monsoon advancement map.
“Conditions are becoming favourable for further advance of Southwest Monsoon into some parts of Central Arabian Sea, Karnataka, some parts of south Konkan and Goa, Andhra Pradesh, parts of Tamil Nadu, West Bay of Bengal, northeast India, Sub-Himalayan West Bengal & Sikkim, parts of Odisha in 4-5 days,” the IMD bulletin read.
Meanwhile, fourteen subdivisions, including drought-ridden Maharashtra, Madhya Pradesh and Chhattisgarh, are facing a deficiency of more than 60 per cent. Deficiency in Vidarbha is at 87 per cent. The shortage of rainfall might further worsen the situation in these states.
