SAFAR predicted that the air quality will improve towards "very poor" only by Thursday. "The AQI is likely to deteriorate to `severe` category for the next two days and improvement towards `very poor` is predicted only by November 14," SAFAR had said in its forecast on Tuesday.

It said under the influence of a western disturbance, no rainfall is expected in the Delhi region but the sky will be partly cloudy with cool temperature during the next two days which may lead to lowering of boundary layer height and accumulation of pollutants near the surface.

On Tuesday the AQI was in the "Severe" category at 453 and the AQI of Delhi was 416, according to the Central Pollution Control Board (CPCB). The AQI of the national capital region was also high with Ghaziabad (445), Noida and Greater Noida (436), Faridabad (404) having a similar experience. Haryana`s Panipat (462), Hisar (406) and Jind (439), too, were in the "severe" category.

The effective stubble fire counts estimated by SAFAR-integrated multi-satellite methodology were 1,846 on Sunday. "Stubble plume intrusion is expected to increase and a decrease in surface wind speed over the Delhi region is forecasted for the next two days," the forecast had said.

SAFAR has advised people to avoid all physical activity outdoors.
