WINTER FOG ARRIVES AGAIN, AVOID EARLY MORNING AND LATE NIGHT TRAVEL PLANS IN THE PLAINS, FOG INTENSITY TO REDUCE IN A FEW DAYS

117

The Hush Post: Foggy mornings and nights are back again. On Thursday morning, dense to very dense fog was witnessed over isolated places in Punjab, Delhi and Haryana. From 05:30 pm on Wednesday to 05:30 am of Thursday, the lowest visibility was recorded at Amritsar and Palam Observatory in Delhi wherein it dropped to less than 25 meters. Hisar  also saw visibility less than 50 metres while visibility in Chandigarh was less than 200 metres. As the Western Disturbance has moved away, the minimum temperatures have dropped significantly over most parts of Northwest India and the Indo Gangetic plains. To add to it, the rains across the northwestern plains of the country have increased the humidity levels, leading to build up of the fog.  Weathermen predict the intensity of fog to reduce again when the next Western Disturbance will approach the Western Himalayas.

Moderate to dense fog is likely at many places during the  next 72 hours in Haryana and Punjab. Partly cloudy sky is expected in the region on Friday.  Two flights were cancelled on Wednesday and air services to Delhi, Pune, Bengaluru and Srinagar were delayed due to poor visibility. The recently started Bangkok flight carrying nearly 40 passengers had to be diverted to Jaipur as it could not be allowed to land at 9.20 am. It only came back here at 12.30 before it departed again at 1.30 pm.  The morning fog hindered rail traffic too, as trains arrived in and departed from the city behind schedule.

The three factors that are conducive for the formation of fog are low temperatures, high humidity and light winds. All these conditions are persisting over the plains of North India, Indo Gangetic plains and Northeast India. So dense fog will persist during late night and early morning hours for the next few days
