New Delhi: The capital recorded “very dense fog” on the first day of the New Year on Friday, with over 50 flights delayed in the early hours as visibility fell to zero at 6am in Palam.
India Meteorological Department (IMD) said “dense” to “very dense” fog prevailed between 4am and 8.30am with conditions only improving slightly later in the day. While no flights were cancelled due to poor visibility, airport officials said 10 flights were cancelled in the morning due to technical glitches and poor destination weather.
Kuldeep Srivastava, scientist, IMD and head, Regional Weather Forecasting Centre said, “By 6am, there was zero visibility at Palam and it remained so till 6.30am before slight improvement. However, it was still below 200 metres until 8.30 am,” he added.
IMD classifies fog as “dense” when visibility is below 200 metres and “very dense” when it is below 50 metres. It is “moderate” when visibility is between 200 and 500 metres.
According to IMD, only moderate fog is expected on Saturday, with shallow fog forecast for Sunday. “Clear skies and moisture lead to dense fog formation, however, a western disturbance will influence the region and lead to a reduction in the fog intensity until January 6. Moderate fog may return by January 7,” said Srivastava.
