Meanwhile, the India Meteorological Department (IMD) has predicted that Northwest India including Punjab, Haryana, Chandigarh, Delhi, and Uttar Pradesh will witness rainfall during February 2-4, 

"Scattered to fairly widespread light/moderate rainfall is very likely over Punjab, Haryana, Chandigarh, Delhi and Uttar Pradesh during February 2 to 4," it said.

The IMD also forecast an isolated hailstorm over Punjab, Haryana and northwest Uttar Pradesh on February 3. The rainfall is likely to occur due to interaction between mid-tropospheric southwesterlies associated with the Western Disturbance and lower level southeasterlies from the Bay of Bengal.

As per the IMD, an active Western Disturbance is very likely to affect northwest India from February 2. "An induced cyclonic circulation is likely to form over southwest Rajasthan and neighbourhood on February 3. In addition, moisture feeding from the Arabian Sea to northwest India at lower and middle tropospheric levels is also very likely on February 2 and 3," the weather agency said.

Apart from this, another Western Disturbance is likely to affect Western Himalayan Region from February 6. The IMD said that light isolated rainfall and snowfall is likely over Jammu-Kashmir-Ladakh-Gilgit-Baltistan Muzaffarabad during the next three days.

Due to the Western Disturbance, surface winds (speed 15-25 kmph) are likely to blow over Punjab, Haryana, Delhi, and Uttar Pradesh during the next two days. The national capital witnessed a clear sky on Sunday with the minimum temperature being recorded at 7 degree Celsius and maximum at 22 degree Celsius.
