The India Meteorological Department has issued a red alert for Delhi-NCR following heavy rainfall and thunderstorms coinciding with the start of the high-profile BRICS Leaders' Summit.
- IMD issued a red alert for Delhi-NCR with forecasts of moderate to heavy rain.
- The weather disruption coincides with the first day of the BRICS Leaders' Summit (Sept 11-13).
- Delhi has already surpassed its annual normal rainfall of 774.4 mm.
The National Capital Region (NCR) was hit by a sudden and intense spell of rainfall on Friday, prompting the India Meteorological Department (IMD) to issue a red alert. The timing of this meteorological event is particularly critical as Delhi begins hosting the BRICS Leaders' Summit from September 11 to 13, welcoming global heads of state including those from Russia, China, and Iran.
According to a district-level nowcast issued at 1 pm, the capital experienced light to moderate rain accompanied by thunderstorms and lightning in its northern sectors. This was followed by more aggressive spells of moderate to heavy rain across the majority of the city. Independent meteorologist Navdeep Dahiya noted that thunderstorm formations originating east of the NCR moved rapidly across the region, affecting Noida, Ghaziabad, Faridabad, and Gurgaon in quick succession.
Why This Matters
BozokMedia analysis shows that such extreme weather events during high-security international summits create significant logistical challenges. From securing open-air venues to managing the movement of VVIP convoys, the red alert forces security agencies to pivot their operational plans. Furthermore, the fact that Delhi has already crossed its annual rainfall norm indicates a shift in regional weather patterns that could impact urban infrastructure during peak diplomatic events.
"The rapid movement of these thunderstorm cells creates short-duration but high-intensity accumulation, which can lead to flash flooding in water-logged urban zones."
The weather shift comes after a five-day dry spell where temperatures had climbed significantly. On Thursday, the maximum temperature at Safdarjung reached 36.6°C, which is 3.1 degrees above the seasonal norm. This temperature spike likely contributed to the atmospheric instability that triggered Friday's heavy downpours.
Historical Background: September is traditionally one of the wettest months for the capital. For instance, in 2021, the city recorded a staggering 413.3 mm of rain. Current data shows that by September 11, Delhi had already received 69.5 mm, accounting for over 55% of its Long Period Average (LPA) for the month.
| Metric | Current Status (Sept 11) | Normal/Historical Average |
|---|---|---|
| Sept Rainfall | 69.5 mm | 120-125 mm (LPA) |
| Annual Norm | Exceeded | 774.4 mm |
| Max Temp (Thu) | 36.6°C | 3.5°C below current |
