The course of the system had been subdued for over a week. However, from Sunday, it has revived and started moving towards the north, weather analysts said.
“It has revived and is moving northwards. It has already reached parts of Gujarat, western Madhya Pradesh, Vidharba, Ordisha and West Bengal,” Mahesh Palawat, told Director of Skymet.
He added that the revival of it towards north was a great indicator that Delhi will receive on-time monsoon rains beginning “this week”.
Till first two weeks of June, rainfall was 19 per cent surplus, but after June 13, they reduced to a deficit of 4 per cent till June 19. However, even when subdued, heavy rainfall activity continued along the western coast and parts of northeastern states.>
