Dense Fog and Low Winds Trap Pollutants

The India Meteorological Department (IMD) reported a thick layer of dense fog and smog blanketing the NCR since morning. Dense fog was recorded on January 19, and moderate fog conditions are expected to persist over the next few days.

Experts attributed the worsening air quality to high humidity levels and low wind speed, which have trapped pollutants close to the ground, preventing dispersion.

GRAP-4 Enforced Across NCR

In response to the severe pollution levels, authorities have implemented Phase 4 of the Graded Response Action Plan (GRAP) across the NCR.

Under GRAP-4 measures:

• Strict checks are being conducted on vehicles entering Delhi

• Polluting vehicles are being stopped

• Construction and related activities have been severely curtailed

Environmental experts warned that unless there is a significant change in weather conditions, such as stronger winds, the situation could worsen further.

The administration has urged people to avoid stepping out unless necessary, wear masks, and take extra precautions for children and the elderly, who are most vulnerable to the harmful effects of severe air pollution.
