As winters have arrived, north India witnessed the first dense fog on Wednesday morning. Fog has been reported also in several areas of northern India including in Delhi, Punjab, Haryana, Chandigarh and west Uttar Pradesh.

Due to this dense fog, people faced difficulty because of low visibility in many areas. Many flights in Delhi and Lucknow airport were delayed because of poor visibility

the India Meteorological Department issued weather warning on Tuesday. It said "shallow to moderate fog is very likely to cover Delhi, Chandigarh, Haryana, Punjab, west Uttar Pradesh, West Bengal, and Sikkim. The fog is expected to last another six days."

According to Sky Met, Palam reported thick fog, with the visibility dropping to 400 meters between 6 am to 7 am. R K Puram, Saket, AIIMS, Dhaula Kuan, East of Kailash, Noida and Faridabad too reported similar visibility conditions.

According to Skymet Weather, the visibility of Palam dropped to 400 meters between 6 am and 7 am after thick fog covered the city. Several neighborhoods in Delhi, including R K Puram, Saket, AIIMS, Dhaula Kuan, East of Kailash, Noida, and Faridabad, were reported with similar visibility conditions.

Skymet also said that "minimum temperatures over the national capital have already dropped. As well, the passage of a Western Disturbance and a depression in the Bay of Bengal have changed the wind pattern to easterly winds, which has increased humidity levels. The combination of these factors has created the dense fog across northern India."
