A rampaging monsoon is currently staging a rare spectacle in the form of a deep depression, which is just a gust away from being a cyclone, over east India.

At no time in recent recorded history has a monsoon low-pressure area intensified thrice over into a deep depression after washing over inland.

Strong flows

This shows how strong the flows are currently despite the fact that a super typhoon (Halong) and a conventional typhoon (Nakri) have been churning up the north Pacific and have sped away to the east-northeast, which is not friendly to the Indian monsoon.

This morning the deep depression lies over north Chhattisgarh, adjoining Jharkhand and northwest Odisha. It is now forecast to move towards the west, generally towards east Rajasthan.

The arrival of a western disturbance into northwest India might lead to its interaction with the monsoon winds from the east and scale up rains further in the whole region from northwest to east India.

Deep trough

The offshore trough along the west coast is in an active phase, rolling out along the whole length from the Gujarat to the Kerala coast.

Most parts of east India, adjoining east-central India, central India, north peninsula and the west coast saw heavy rain until this morning.

The India Met Department said in a morning update that yesterday the monsoon was vigorous over Odisha and Konkan-Goa and active over Gangetic West Bengal, east Uttar Pradesh, Chhattisgarh, coastal and south interior Karnataka and Kerala.

Very to very heavy rainfall has been forecast for east India, central India, west coast and parts of peninsular India for the next couple of days.
