Delhi NCR: IMD Alerts and Warnings
The India Meteorological Department (IMD) has warned of continued cold wave conditions with minimum temperatures markedly below normal at isolated places and appreciably below normal across most parts of Delhi. A shallow fog advisory remains in effect for the weekend, with mist and haze expected during morning hours from December 5 to 11. The IMD has also noted that surface winds from the northwest direction at speeds of 15-20 kmph during daytime may help disperse pollutants but will also enhance the chill factor.
Temperature Forecast for the Weekend
For Saturday, December 6, the minimum temperature is likely to hover around 8°C, while the maximum may reach 23°C, with humidity levels touching 100% in the morning and dropping to 68% by evening. The forecast for Sunday, December 7, shows a slight improvement, with temperatures ranging between 8-10°C minimum and 23-25°C maximum, accompanied by partly cloudy skies and shallow fog during morning hours. By Monday, December 8, the minimum temperature is expected to stabilize near 8-10°C, with maximums around 24-26°C, as wind speeds increase to 20 kmph in the afternoon.
Delhi NCR Air Quality Update
Delhi's air quality has deteriorated significantly, with the AQI reaching 333 on Saturday, classified as 'very poor'. Of the 39 monitoring stations across the city, 35 registered readings in the 'very poor' range, while four reported 'poor' air quality. The smog has thickened, with particulate matter PM2.5 levels at 187 µg/m³ and PM10 at 242 µg/m³, well above safe limits. The ventilation index is expected to remain low, limiting the dispersion of pollutants over the weekend.
The weekend outlook indicates a gradual improvement in weather conditions, with mainly clear skies expected after Saturday and temperatures slowly returning to near-normal levels by December 8. However, health advisories have been issued for vulnerable groups, including children, the elderly, and those with respiratory conditions, to avoid outdoor activities during early morning hours when fog and smog are thickest. Residents are advised to wear warm clothing, use masks outdoors, and keep windows closed during peak pollution hours.
