Red alert issued over dense fog; AQI remains 'very poor'

With a dense fog engulfing most parts of North India, the India Meteorological Department (IMD) has issued a red alert for Delhi-NCR, and an orange alert for several Uttar Pradesh districts such as Agra, Aligarh, Baghpat, Bareilly, Bijnor, Bulandshahr, Etah, Etawah, Firozabad, Gautam Buddha Nagar, Ghaziabad and others. 

An orange alert was also issued for Uttarakhand's Haridwar and Udham Singh Nagar, and Punjab's Amritsar, Fatehgarh Sahib, Gurdaspur, Patiala and Sangrur. It advised the people to remain inside their residences as the reduced visibility could lead to accidents.

"Residents in the affected regions are advised to stay alert and take necessary precautions, including being careful while driving or travelling by any mode of transport, using fog lights, checking road and traffic conditions, staying in touch with airlines, railways and state transport authorities for travel schedules, avoiding unnecessary travel and following advisories issued by concerned agencies," the IMD said.

On Friday, the air quality index (AQI) in Delhi-NCR also remained in the 'very poor' category after it was recorded at around 382. Officials believe that the AQI will remain in the 'very poor' category till Saturday and may even deteriorate to 'severe' category on Sunday.
