Light rainfall with calm winds might worsen the situation rapidly

Authorities said the severe air quality is due to unfavorable meteorological conditions.

It said sufficient rainfall that is predicted for today might improve the air quality but also warned that little showers with calm winds would only aggravate the situation rapidly.

As per the Center-run System of Air Quality and Weather Forecasting (SAFAR) model, fog intensity is likely to decline with increased gusty winds.

"An active western disturbance is very likely to cause fairly widespread moisture intrusion over the northern region, including Delhi, but only after three days when withdrawal is expected," said SAFAR.

In view of the air quality in Delhi, the Supreme Court-appointed Environment Pollution Control Authority (EPCA) had ordered a 24-hour ban on the entry of trucks into the national capital recently.


Trucks will be disallowed to enter till 11 pm today

The entry of trucks to Delhi would be disallowed "from 11 pm on Friday to 11 pm on Saturday in view of the severe pollution in the city", the EPCA had instructed authorities.

In a letter to the chief secretaries of Delhi and the neighboring states of Uttar Pradesh and Haryana, EPCA chief Bhure Lal directed them to stop the entry of trucks.

Ban imposed on trucks for second time this season

Lal directed except for those trucks carrying essential commodities, rest all should be stopped during the period. This would be the second time this season that a ban on the trucks' entry would be imposed. Earlier, it was done in November when air quality deteriorated.
