The onset of winter is here and with decrease in temperature, air pollution is expected to rise, bringing the smog back in Delhi. According to the weathermen, weak western disturbances have started moving towards Northwest India and Himalayan areas. Due to this weather system, higher areas in the Himalayas are expected to receive light snowfall.
As a result open areas and fields in northern India will witness clear skies but wind speed is likely to slow down. The air pollution level is hovering at 350 in some parts of Delhi and NCR. Levels of PM 2.5 stand at 174 at present, which is twice the permissible limit. It is also being predicted that PM 2.5 levels will increase to 226 in the coming three days.
