The Indira Gandhi International Airport is expected to experience low visibility conditions owing to fog and smog over the next two days.
The India Meteorological Department (IMD) has said that wind movement has weakened due to western disturbances affecting North India for the first time after the monsoon giving rise to fog.
“Fog and smog have redeveloped over Delhi with the weakening of winds and it is likely to stay that way at least for next two days,” a Met official said.
“The first western disturbance would affect north India between October 31 and November 1. During this period, light westerly winds, which are presently in the lower levels of the atmosphere, may change to light easterly for a day in Delhi,” R K Jenamani, director in-charge of the IGI Met office, said.
Jenamani said the fog and smog will also affect visibility at
“The airport visibility has gone down by 30 per cent to 40 per cent when compared to Monday. On Monday, the visibility was from 1,000 metres to 3,000 metres. This came down to 600 metres to 1,500 metres on Tuesday,” he said.
The impact of western disturbances is likely to ease by November 2 and there is a 60 per cent chance of Delhi getting moderate north-westerly winds.
“Smog is likely to thicken due to pollution from Diwali crackers. How far this would intensify the smog would be clear by Thursday,” Jenamani said.
