New Delhi: For the fourth consecutive day, the national capital is choking under the thick smog that has covered Delhi and the adjacent areas. The overall air quality in the national capital remained in the 'severe' category on Saturday. According to the System of Air Quality and Weather Forecasting and Research (SAFAR), the overall air quality of the national capital docked at 505 at 7:30 am on Saturday.

The weatherman has forecast mainly clear skies for the day with the maximum temperature likely to hover around 28 degrees Celsius. There is also a possibility of strong surface winds.

SAFAR stated that the overall Delhi AQI shot up very fast towards the higher side of the severe category mainly due to secondary particulate formation after Delhi experience slight drizzle which is always lethal as also happened in the first week of November. Although PM2.5 is recovering during the daylight, Western Disturbance induced cloudy conditions prevailing over entire northwest India may bring some isolated drizzle in Delhi to offset the day gain, according to SAFAR. "Drizzling delayed the recovery and hence, improvement to the very poor category is now expected only by November 17," it added.
