Delhi wakes to overnight rain, cleaner skies and slightly better air quality

Overnight rainfall in Delhi and the surrounding NCR offered temporary relief, slightly improving air quality and raising temperatures. The rain also reduced the biting chill, but pollution levels remain alarming. Authorities reported no cases of flooding or waterlogging after the downpour.

Despite the rain, Delhi’s air quality remains a pressing concern. On Thursday, the Central Pollution Control Board recorded an Air Quality Index (AQI) of 356, placing it in the ‘very poor’ category. The situation worsened earlier this week, prompting stricter pollution control measures.

The Commission for Air Quality Management reintroduced measures under GRAP-3 and GRAP-4 to curb rising pollution. These graded response measures aim to limit activities that contribute to smog, such as construction work and industrial emissions.

Officials noted a sharp rise in pollution due to weather conditions. On January 14, Delhi recorded an AQI of 275. However, dense fog, low temperatures, and minimal wind dispersal caused pollutant levels to spike. On January 15, the AQI climbed to 386, eventually reaching 396 by evening. The trend suggests AQI may breach the critical 400 mark soon, according to forecasts from the India Meteorological Department (IMD) and IITM.

In response to the worsening air quality, the Delhi Directorate of Education issued orders for hybrid learning. Students in Classes IX and XI can attend online classes to reduce outdoor exposure. Schools are preparing to manage classes in dual modes to ensure continuity in education.

Delhi continues to endure a cold wave, further exacerbating pollution levels. Low temperatures and dense fog trap pollutants closer to the ground, reducing dispersion. The unfavorable weather pattern keeps pollution levels elevated despite intermittent rain.

With pollution levels approaching critical levels, authorities may announce additional restrictions. Citizens are advised to limit outdoor activities, use masks, and avoid prolonged exposure to polluted air. The situation highlights the need for long-term solutions to tackle recurring pollution crises in Delhi and its neighboring areas.

The overnight rain brought some relief, but the battle against toxic air continues.
