The India Meteorological Department (IMD) has forecast a generally cloudy sky with light rain for today in the city with maximum and minimum temperature at 20 degrees and 13 degrees Celsius, respectively.

The air quality in the national capital on Thursday morning plunged to "severe levels" for the second consecutive day, said System of Air Quality and Weather Forecasting and Research (SAFAR).

According to SAFAR, the rise in air pollution is because of the prevalence of calm surface winds and decrease in ventilation coefficient which creates a conducive environment for pollutant accumulation.

The PM 10 levels were slightly better at Lodhi Road, docking in at 135 which falls in the 'moderate' category while the PM 2.5 remained 'poor' at 235.

Arvind Kejriwal-led Delhi government's Odd-Even scheme ended on Friday. The Chief Minister had said that state government will take a decision on Monday on the continuation of the scheme.

Delhi is again in the grip of toxic air with air quality index falling to severe level. Residents are facing huge difficulty in breathing, walking and going out in public.

The court also directed the Centre to prepare a road map for installation of air-purifying towers to deal with the pollution crisis in the national capital.

Air quality condition is likely to marginally improve by tomorrow (Friday), but a reasonable improvement to the 'very poor' is expected only by November 16 (Saturday).
