IMD has issued an orange alert from Delhi-NCR over the next two days and red alert for Punjab for the same period as the cold wave sets in North India.
The weather department has also issued a yellow alert for December 31 and January 1 as the cold wave can further intensify into a severe cold wave.
The India Meteorological Department (IMD) has 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.”
On Tuesday, Safdarjung recorded 3.6 degrees Celsius temperature at 8:30 am, which is likely to fall by another 2 degrees over the next 24 hours, said the IMD.
A cold wave is likely to grip parts of Delhi also over the next four days as frosty winds from the Himalayas have started blowing towards the plains, weather officials said.
The IMD said cold wave to severe cold wave conditions are also likely in isolated pockets over Uttar Pradesh. Isolated cold wave conditions are likely over Bihar, Jharkhand, Gangetic West Bengal and Odisha during December 30-31.
