On Sunday, Delhi-NCR awoke to a dense fog, causing significant disruptions with over 100 flights and 22 trains experiencing delays due to poor visibility. The minimum temperature in the national capital was recorded at 3.5 degrees Celsius, four notches below the seasonal average, as reported by the India Meteorological Department (IMD).
The dense fog led to the lowest visibility recorded at zero in Safdarjung at 8 a.m., with Palam also reporting zero visibility at 5 a.m. The IMD categorizes fog intensity into four types: shallow, moderate, dense, and very dense, with visibility ranging from 999 m to less than 50 m.
Indian Railways reported delays of 22 trains due to fog and the prevailing cold wave. Road traffic was severely impacted as visibility reduced to a few feet.
Several areas in Delhi experienced 'severe' air quality, prompting the weather office to issue a red alert due to the cold and fog conditions. The IMD forecast indicates that dense fog is expected to persist in Delhi until Tuesday.
The city had previously encountered its first cold wave day of the season on January 12, with temperatures dropping to 3.9 degrees Celsius. Saturday marked the coldest night so far, recording a season-low temperature of 3 degrees in Aya Nagar, the last village on the Mehrauli-Gurgaon Road in Delhi.
