Delhi-NCR braces for more rain as IMD issues alert for another spell of ‘heavy’ showers– full weather report here
Delhi-NCR Faces Another Round of Heavy Showers as IMD Escalates Rainfall Watch
Theindiapostdaily.com – After just two days of intense downpours that saturated the capital's already strained drainage network, Delhi and its surrounding National Capital Region are bracing for yet another bout of heavy rainfall. The India Meteorological Department issued a fresh rainfall alert on Sunday, 6 September, covering the national capital along with multiple neighbouring states, signalling that the monsoon's grip on northern India is far from loosening.
IMD Alert and Atmospheric Setup
The meteorological department's advisory, published on its X (formerly Twitter) account, described the positioning of a Low Pressure system that is driving the renewed instability. The department noted:
"The Low Pressure area over northwest Madhya Pradesh & adjoining southwest Uttar Pradesh lay over Southwest Uttar Pradesh & neighbourhood at 0530 hrs IST of today, the 06th September 2026. It is likely to move east-northeastwards during next 24 hours."
Prevailing atmospheric conditions point toward the possibility of heavy rainfall at isolated locations across Punjab, Haryana, Chandigarh, Delhi, eastern Rajasthan, Madhya Pradesh, Uttar Pradesh, and Uttarakhand. Every one of these states has been placed on a yellow alert for the day. The broader synoptic picture shows the monsoon trough sitting at mean sea level, threading through Sri Ganganagar, Delhi, the centre of the Low Pressure area over southwest Uttar Pradesh and its neighbourhood, Satna, Daltonganj, and Bankura before curving eastward toward Tripura. This elongated trough configuration is what keeps feeding moisture into the northern plains and sustains the repeated cycles of heavy rain that have characterised the season so far.
What Delhi Can Expect Today
The weather office's forecast for the capital calls for a generally cloudy sky with spells of very light to light rain likely at many locations during the afternoon or evening hours. Temperatures are expected to hover near normal: maximum readings in the neighbourhood of 24 °C to 26 °C, deviating between −1.5 °C and +1.5 °C from the climatological mean. Minimum temperatures, meanwhile, are projected to settle between −1.6 °C and −3.0 °C below normal, landing in the 31 °C to 33 °C band. The combination of elevated humidity, low cloud cover, and periodic showers will keep the perceived temperature uncomfortably high through the day.
Aftermath of Saturday's Downpour
The alert comes on the heels of a punishing 24-hour period that began on 5 September, when residents woke to heavy rainfall, thunderstorms, and gusty winds under an orange alert issued by IMD. That single day delivered 29.8 mm of rain to the capital, pushing the cumulative annual total to 814.5 mm — already well above the city's long-period average of 774.4 mm. Station-level data showed Palam recording the highest accumulation at 35.6 mm, while Lodhi Road logged 30.8 mm in the 24-hour window ending at 8:30 AM on 6 September.
The sudden deluge, which coincided with the Janmashtami festival, snapped a brief dry spell and overwhelmed the city's drainage infrastructure within hours. Major arterial roads, low-lying neighbourhoods, and underpasses turned into temporary waterways, producing severe traffic congestion at several prominent junctions. The area surrounding Indira Gandhi International Airport was particularly affected: waterlogged stretches around the terminals disrupted ground operations and forced commuters to wade through inundated walkways, compounding flight delays and passenger confusion.
Broader Monsoon Outlook for India
The active monsoon is not confined to the north. Eastern and northeastern India remain squarely in the path of the trough's eastern extension, with heavy showers forecast for Arunachal Pradesh, Assam, Meghalaya, Bihar, Nagaland, Manipur, Mizoram, Tripura, sub-Himalayan West Bengal, and Sikkim. For residents of these states, the coming days carry a heightened risk of flash flooding, landslides in hilly terrain, and disruption to river-transport and road connectivity. Authorities in affected districts are advised to maintain vigilance, monitor IMD bulletins closely, and ensure that drainage channels and flood-warning systems remain operational ahead of the next round of intense precipitation.
For Delhi specifically, the recurrence of heavy-rain events within a matter of days underscores a structural vulnerability: the capital's drainage capacity, designed for a different rainfall regime, is being tested repeatedly by a monsoon that is delivering above-average totals well before the season's traditional peak. Each successive episode compounds the stress on ageing infrastructure, and the cumulative annual figure already exceeding the long-period average suggests that the coming weeks will demand sustained preparedness from both municipal agencies and residents alike.
