The India Meteorological Department (IMD) has declared that the South-West monsoon has withdrawn from some parts of West Rajasthan and Punjab on Monday after having been delayed for almost a month by various active rain spells in September.
This is the seventh consecutive year that the monsoon has delayed its withdrawal from West Rajasthan. Last year (2019) saw the withdrawal begin only on October 9, the most delayed in recorded history.
The withdrawal dates in the previous years are September 29, 2018; September 27, 2017; September 15, 2016; September 4, 2015; and September 23, 2014. The other most delayed withdrawals in the past were recorded in October 1, 1961, followed by September 30, 2007.
Rain deficit in hill regions
The IMD said on Monday that the main rain-driving feature of the monsoon trough over the plains of North India has become disorganised, signalling that the seasonal weather system is preparing to exit more parts of North-West and Central India in the next few days.
Conditions are becoming favourable for further withdrawal of the monsoon from more parts of Rajasthan and Punjab and some parts of Haryana, Chandigarh, Delhi, Uttar Pradesh and Madhya Pradesh during the next two-three days after leaving major rain deficits over the hill regions.
But, as expected, the withdrawal might run into token resistance over East and North-East India since a trough capable of generating rain, lightning and thunderstorms runs from a cyclonic circulation over East Bihar into the Bay of Bengal, itself a remnant of an erstwhile low-pressure area from the Bay.

The trough runs down to the West-Central Bay off the Andhra Pradesh coast across the plains of West Bengal and coastal Odisha. Scattered to fairly widespread rainfall with moderate thunderstorm is forecast over parts of the South Peninsula during next the next three days.
Isolated heavy falls are also forecast over Tamil Nadu during next two days and over Rayalaseema, South Interior Karnataka and Kerala on Tuesday. Usually, the East Coast and the South-East Peninsula get rain when the larger monsoon system weakens over the country.
