Moderate to dense fog in Delhi, Haryana and parts of Punjab

According to the India Meteorological Department’s Airport Meteorological Service, the fog cover extended across the National Capital Region on Monday morning including Noida, Gurugram, Ghaziabad and Faridabad. IMD forecasts suggest shallow to moderate fog during morning hours for the next six days across Delhi, Haryana, western Uttar Pradesh, Punjab and parts of Rajasthan.

At Lucknow, visibility was likely to drop to 800 metres in shallow fog during early hours before improving later in the day. Jaipur was expected to see shallow fog with visibility reducing to 600 metres, improving to mist by morning. Amritsar recorded dense fog conditions with visibility falling to 100 metres, before gradual improvement.

Western disturbance likely to persist till February 5, says IMD 

Meteorologists say the fog spell is being driven by a persistent western disturbance over north Pakistan and adjoining areas, coupled with an induced cyclonic circulation over Haryana and neighbouring regions.

Moisture incursion and calm surface winds have created favourable conditions for fog formation across the Indo-Gangetic plains.

A fresh, feeble western disturbance is likely to affect the higher Himalayan region from the night of February 2, while another system is expected to impact northwest India from February 5, potentially prolonging cloudy conditions and fog episodes.
