Summary:
NEW DELHI: Delhi’s air quality nosedived to ‘severe’ for only the third time this season on Friday. Forecast agencies say the air quality can deteriorate further on Saturday before a western disturbance in the region effects an improvement from November 11.The SAFAR forecast said on Friday that a heavy air mass was coming towards Delhi at low wind speeds. The Central Pollution Control Board logged an overall Air Quality Index (AQI) of 423 at 4 pm, which was higher than Thursday’s 390 (‘very poor’). “The CPCB-led task force will take a call on Saturday whether these measures need to be extended.” However, the rise in the pollution levels in the past 24 hours is primarily due to low temperatures, sluggish wind speed and winds blowing in from the north-west..
