New Delhi (NVI): A cold wave is expected to the national capital with moderate to dense fog in the next four days, according to the India Meteorological Department (IMD) forecast.
On Tuesday, the Safdarjung observatory recorded the minimum temperature at 3.6 degrees Celsius.
A cold wave is likely to grip parts of Delhi over the next four days as frosty winds from the Himalayas have started blowing towards the plains, weather department said.
Cold wave occurs in plains when the minimum temperature is 10 degrees Celsius or below and/or is 4 notches lesser than the season’s normal for two consecutive days. Cold wave is also declared when the minimum temperature is less than 4 degrees Celsius in the plains.
“In Delhi, we are expecting moderate to dense fog so visibility may be under 200m in some parts of the Capital. The western disturbance which was affecting the Western Himalayas has just passed so there is moisture in the air and wind speed is also likely to reduce. Its going to be very cold also, leading to the development of fog,” IMD stated.
Meanwhile, air quality continued to improve, with the hourly average air quality index (AQI) at 7am recorded at 233. Central Pollution Control Board data showed that on Monday, the overall AQI of Delhi was 253.
In addition to this, ‘cold wave’ to ‘severe cold wave’ conditions are likely in some pockets over Uttarakhand, Himachal Pradesh, Punjab, Haryana, Chandigarh, Delhi and north Rajasthan in the next four days, the weather department added.
The India Meteorological Department (IMD) also said, “Dense to very dense fog is likely in some pockets over Punjab, Haryana, Chandigarh, Delhi and Uttarakhand over the next 3-4 days. Dense fog in isolated pockets is very likely over Uttar Pradesh over the next three days and over Rajasthan in the next two days.”
