It worsened further last Sunday as Delhi recorded 'severe' air quality and stayed so on Monday and Tuesday

Favorable wind conditions brought slight relief on Thursday but the air quality began deteriorating again, nearing the 'severe' category, on Friday. Delhi's air quality slipped back to the 'severe' category on Saturday

The 'severe' category poses serious health risks, especially due to fine particulate matter (PM2.5), which can penetrate deep into the lungs and enter the bloodstream, causing long-term health issues

It has forecast shallow fog during the morning or night hours, with the maximum temperature expected to hover around 28 degrees Celsius. The humidity level at 8:30 am stood at a high 75 percent
