The weatherman has attributed the unseasonal rains to a fresh extra-tropical weather system and its induced low pressure area that would affect western Himalayan region, northwest and adjoining central India.
Besides Delhi, the system is expected to bring rain to many parts of north Rajasthan, Punjab, Haryana and West Uttar Pradesh.
"The rainfall over Delhi is likely to begin on the early morning of 23rd and continue till the next morning," the India Meteorological Department said in a statement.
The weatherman has advised farmers in Punjab, Haryana, Rajasthan, Uttar Pradesh and Madhya Pradesh withhold the irrigation in their fields.
Parts of Jammu and Kashmir, Himachal Pradesh and Uttarakhand are expected to get heavy to moderate rain or snowfall between February 21 and 24.
This would be the third spell of rains due to an extra-tropical weather system, commonly called as western disturbance, to affect the north-west India since the beginning of this month.
The weatherman said such systems are not uncommon in February and normally five western disturbances affect the region during the month.
New Delhi: Northwest and central parts of the country are set to experience yet another wet spell this weekend making it the wettest February for the region.
