The air quality in the national capital on Wednesday continues to remain in the 'very poor' category with an overall Air Quality Index (AQI) at 343, according to the System of Air Quality and Weather Forecasting and Research (SAFAR).

The SAFAR in its bulletin predicted rainfall on February 3 and 4, with a gusty wind that is expected to improve AQI to 'lower end of Very Poor' or 'Poor' through wet deposition and strong dispersion.
"AQI today indicates 'Very Poor' air quality and likely to be the same for the next 2 days (1st and 2nd) as the prevailing weather conditions are unlikely to change significantly. On 3rd and 4th, rainfall is likely to occur with a gusty wind that is expected to improve AQI to 'lower end of Very Poor' or 'Poor' through wet deposition and strong dispersion," it said.
It further said that from February 5 onwards the air quality will gradually degrade as the rate of accumulation of pollutants is likely to be more than that of ventilation.
The bulletin advised all people belonging to sensitive groups to avoid all physical outdoor activities.
"Avoid all Physical activity outdoor and move activities indoors. If asthematics, keep relief medicine handy," it read.
