6India Meteorological Department (IMD) has said that the withdrawal of the South-West monsoon has resumed from North-West India on Tuesday, with reduction in moisture content and cessation of rainfall over more parts of the region.
Thus, the monsoon has exited the whole of Rajasthan; more parts of Uttar Pradesh and Madhya Pradesh; most parts of Gujarat and some parts of the North Arabian Sea.

How long the monsoon withdrawal progresses would depend on an ongoing rain session over East and Central India, and the predicted fresh spurt in rainfall with the formation of a fresh low-pressure area over the North Andaman Sea and adjoining Bay of Bengal by Friday.
The IMD has maintained a watch for it to move North-West towards and intensify as a depression by Saturday. This would bring enhanced rainfall to Andhra Pradesh, Telangana, Tamil Nadu, Puducherry and isolated heavy falls are also likely over Tamil Nadu and Telangana from Friday.
A prevailing low has weakened into a cyclonic circulation over South Coastal Odisha on Tuesday afternoon. But it has thrown open a trough back to East Bihar across the plains of West Bengal and signalled fairly widespread-to-widespread rain over East and North-East India, including hills of West Bengal and Sikkim on Tuesday.
Withdrawal of the monsoon from the North-West has allowed cool north-westerly (Arctic) winds to blow in from Pakistan/Afghanistan and cause the night temperatures to dip during the past few days, the IMD said.
