Met Department Warns of Continued Thunderstorms
Atmospheric conditions over the national capital shifted aggressively on Tuesday, July 28, 2026, as dark cloud cover preceded consistent moderate to heavy showers. The India Meteorological Department (IMD) responded by issuing an orange alert, signaling a need for public vigilance amid deteriorating weather conditions. Forecasters anticipate the current system will sustain overcast skies, thunderstorms, and high-velocity winds throughout the immediate period.
Rainfall Distribution and Thermal Relief
Data collected by various monitoring stations reveals the uneven intensity of the recent downpour. By 8:30 a.m. on Tuesday, primary weather stations recorded significant accumulation:
- Ridge: 37.6 mm
- Lodi Road: 36.7 mm
- Safdarjung: 32.4 mm
- Ayanagar: 4.0 mm
- Palam: 0.8 mm
This follows a Monday afternoon (July 27) that saw Ridge and Lodi Road receive 19.4 mm and 11.5 mm respectively. The influx of moisture brought the minimum temperature at Safdarjung down to 25.5 degrees Celsius, which is 1.8 notches lower than usual for this time of year.
Satisfactory Air Quality Amid Flooding
While the heavy rains disrupted transit and caused waterlogging on major thoroughfares, the precipitation had a positive impact on atmospheric pollutants. The Central Pollution Control Board reported an Air Quality Index (AQI) of 77 at 9 a.m., placing the city firmly in the satisfactory category. This metric falls within the 51 to 100 range, a notable improvement compared to the higher ranges classified as poor or severe.
