“With mainly clear skies on Thursday, smog/mist is likely during the evening and night. Predominant wind is likely from the northwest direction with a speed of less than 10 kmph during the morning and night. It may increase up to 16 kmph during the afternoon. A ventilation index lower than 6000 m2/s and average wind speed of less than 10 kmph is unfavourable for dispersion of pollutants,” warned Safar.
