A rampaging monsoon is presently orchestrating a rare spectacle in the form of a deep depression – a gust away from being a cyclone – over east India.
At no time in the recent recorded history has a monsoon low-pressure area intensified thrice over to become a deep depression after emerging inland from sea.
Strong flowsThis shows how strong the flows are currently, despite 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.
The deep depression lay practically stationary over north Chhattisgarh, adjoining Jharkhand and north-west Odisha since Tuesday morning.
It is now forecast to move towards the west, generally towards east Rajasthan.
Arrival of a western disturbance into north-west India might lead to interaction with the monsoon winds and scale up rains further in north-west to east India.
Trough shiftsThe offshore trough along the West Coast has switched alignment from Tuesday afternoon with the southern end shifting away from Kerala to Lakshadweep.
Most parts of east India, adjoining east-central , central parts, north peninsula and the West Coast saw heavy rain until this morning.
India Met Department said that the monsoon was vigorous yesterday over Odisha and Konkan-Goa; and active over Gangetic West Bengal, east Uttar Pradesh, Chhattisgarh, coastal and south interior Karnataka and Kerala.
Heavy to very heavy rainfall has been forecast for east and central parts, West Coast and parts of peninsular India for the next couple of days.
