“Delhi’s air quality is likely to improve and remain in the ‘very poor’ category from November 26 to 28. The outlook for the subsequent six days shows the air quality is likely to remain in the ‘very poor’ category,” said the Early Warning System (EWS) for Delhi, a forecasting model used by the CAQM.
According to the IMD forecast, a prevailing western disturbance over northwest India would impact Delhi on Monday.
“The wind direction has changed and easterly winds are starting to blow towards Delhi, as the western disturbance, which is primarily impacting Rajasthan and the western Himalayan region, approaches. This is raising the minimum temperature again, which will start dipping again from Tuesday when cold northwesterly winds return.”
Delhi recorded its lowest minimum temperature this season on Thursday when it touched 9.2 degrees Celsius.
