Delhi Under IMD Red Alert as Heavy Monsoon Rain Floods Roads and Snarls Airport Traffic

On Tuesday, August 25, 2026, the India Meteorological Department (IMD) placed all 11 districts of Delhi under a red alert for thunderstorms, lightning, gusty winds, and intense rainfall — the second straight day of monsoon disruption across the Delhi-NCR region. Heavy showers that began on Monday, August 24 left roads waterlogged, commuters stranded in gridlock, and Indira Gandhi International Airport (IGIA) coping with 15 flight diversions, widespread delays, and cancellations.

Editor’s note: This article draws on IMD district warnings, reporting by The Hindu (PTI), Hindustan Times, The Tribune, and India TV News, August 24–25, 2026. Rainfall totals and transport status may update as the monsoon spell continues.

What the IMD red alert covers

The IMD issued a district-wise nowcast warning at 7:13 a.m. IST on August 25, valid through 10:13 a.m., forecasting:

• Thunderstorms with lightning
• Gusty winds of around 60 km/h
• Heavy rain exceeding 15 mm per hour

All 11 administrative districts — Central, East, New Delhi, North, North East, North West, Shahdara, South, South East, South West, and West Delhi — were placed under the highest-tier warning. Officials advised residents to stay alert, avoid shelter under trees or weak structures, and expect further spells through the day.

Warning level	Areas (Aug. 25)	Main hazards
Red	All 11 Delhi districts	Thunderstorms, lightning, 60 km/h gusts, >15 mm/h rain
Orange	Parts of Uttar Pradesh, Kerala, Madhya Pradesh, Haryana, Uttarakhand	Heavy to very heavy rain at isolated locations
Subdivision	Haryana, Chandigarh, Delhi combined	Continued heavy rain, thunderstorms, lightning

A broader subdivision-level warning also covered Haryana, Chandigarh, and Delhi for August 25, with forecasters noting that moderate rain was likely at many places and heavy to extremely heavy falls possible at isolated spots — raising the risk of fresh waterlogging and transport delays.

Monday’s downpour: rainfall totals

Monday’s intense spell set the stage for Tuesday’s alerts. IMD observations showed moderate rain at most locations and heavy rain at isolated sites across the capital.

Station / area	Rainfall (approx.)	Period
Janakpuri	70 mm	Mon., 8:30 a.m.–5:30 p.m.
Ayanagar	69.1 mm	Same window
Palam	58.2 mm	Same window
Chhatarpur	57 mm	Through early afternoon
Lodi Road	41.7 mm	Same window
The Ridge	43.2 mm	Same window
Safdarjung (base station)	34.6 mm	Same window
Pitampura	35 mm	Through early afternoon

Between 8:30 a.m. and 11:30 a.m. alone, Chhatarpur logged 28 mm, Lodi Road 24.6 mm, and Pitampura 18.5 mm. Safdarjung recorded a maximum temperature of 32.3°C — 1.8 degrees below normal — and a minimum of 27.8°C.

Waterlogging and traffic chaos

The volume of rain overwhelmed drainage across the capital and its suburbs, turning major corridors into slow-moving pools.

Delhi

Water accumulation was reported in:

• Kamla Nagar, Kishanganj underpass, and Baba Kharak Singh Marg near Parliament
• Connaught Place (inner and outer circles), Mathura Road, Bhairon Marg, and ITO
• Zakhira underpass, New Ashok Nagar Metro station, Burari, CR Park, Alaknanda, Sangam Vihar, and Bhalswa
• Sarai Kale Khan–Mathura Road, Dwarka Expressway, and stretches of Lutyens’ Delhi

Visuals from the city showed commuters wading through waist-deep water in Sangam Vihar and Sadar Bazar in Old Delhi. Near Shivaji Stadium, flooding was severe enough to stall buses and cars for hours.

Gurugram and wider NCR

Gurugram recorded roughly 70 mm of rain by 1:30 p.m., with deep water at Narsinghpur, Hero Honda Chowk, Rajiv Chowk, IFFCO Chowk, Naharpur underpass, and older sectors along Railway Road, Mehrauli Road, and Basai Road. Parents were seen carrying children on their shoulders to reach school buses; ambulances and buses were stuck on Sohna Road.

The district administration asked corporate offices and educational institutions to shift to work-from-home where possible to ease road pressure and assist drainage crews.

Ghaziabad and Noida also reported flooded low-lying sectors and long jams. In Alwar (NCR), Kherthal-Tijara and Kishangarhbas saw markets and residential colonies inundated.

Airport disruption at IGIA

Bad weather at Indira Gandhi International Airport forced significant schedule changes on Monday:

Impact	Detail
Diversions	15 flights rerouted
Destinations	12 to Jaipur, 2 to Chandigarh, 1 to Lucknow
Other effects	Scores of delays; some cancellations

Airport officials cited low visibility, wind shear risk, and standing water on aprons and access roads as contributing factors. Passengers were urged to check carrier apps before heading to the terminal.

Rain beyond Delhi-NCR

The monsoon low-pressure system affecting north India also brought disruption elsewhere:

• Jaipur and eastern Rajasthan: submerged Moti Dungri Road; traffic jams across Alwar, Dholpur, Karauli, Bharatpur, and Sawai Madhopur districts
• Uttar Pradesh: light to moderate showers with isolated heavy bursts; an autorickshaw overturned on a waterlogged Ghaziabad stretch — passengers escaped with minor injuries
• Himachal Pradesh: 98 roads closed; 21 power transformers and 21 drinking-water schemes disrupted, per the State Emergency Operation Centre
• Odisha: eight places logged more than 100 mm in 24 hours; Joda (Keonjhar) topped 169.4 mm

What officials recommend

The IMD’s standing guidance for red-alert conditions applies across Delhi on August 25:

• Avoid non-essential travel during peak storm windows
• Do not shelter under trees, billboards, or construction scaffolding
• Unplug non-essential electronics if lightning is nearby
• Do not drive through water of unknown depth — underpasses can flood faster than they appear
• Monitor municipal traffic advisories and airline updates before commuting

Forecasters expect improving conditions from Wednesday, August 26, though scattered showers may linger across the NCR subdivision.

Why Delhi floods so quickly

Delhi’s monsoon flooding is a recurring urban challenge. The city sits on a flat alluvial plain with aging storm drains, rapid surface paving, and seasonal pressure on the Yamuna floodplain. A few hours of intense rain — common during active monsoon troughs — can exceed the capacity of local drainage even when total seasonal rainfall is within normal bounds.

Monday–Tuesday’s event fits that pattern: localized totals above 60–70 mm in a single afternoon overwhelmed underpasses and market streets long flagged as choke points, while the airport — built on the city’s southwestern fringe — faced simultaneous wind and visibility constraints.

Discussion

1. Should Gurugram-style work-from-home orders become standard during red-alert monsoon days across NCR?

Delhi’s economy runs on daily commuting. Mandating remote work helps clear roads for emergency vehicles and drain crews — but it also hits daily-wage workers, retail staff, and students who cannot log in from home. Where should the line be drawn?

2. After repeated flood seasons, what would actually fix Delhi’s underpass problem?

Zakhira, Kishanganj, and Naharpur flood almost every heavy-rain year. Pump upgrades, permeable paving, and stricter building runoff rules are often discussed — yet knee-deep water returns. Is this a funding issue, a governance issue, or a planning issue that no single monsoon budget can solve?

If you were commuting through Delhi or NCR on August 24–25, share what you saw — and whether you changed plans because of the alerts.
