When M. Aditya came out of his office in Gachibowli, Hyderabad at around 8 pm on Tuesday (June 9, 2026), the rain had already stopped. But the condition of the city was also the same.
Outside, the roads were wet with rain, traffic was at a standstill, and a sea of red taillights stretched into the distance. It usually takes them around 50 minutes to travel back to their home at ECIL, NagaramThe minutes turned into a three-and-a-half-hour ordeal of unsuccessful cab bookings, long walks to the nearest metro station, packed trains and gridlocked roads. When he reached home it was 11:30 at night
He recalls, “It was a nightmare. Just a few minutes of rain brought the entire traffic system to a halt.”
Aditya’s experience was not unusual. Throughout Cyberabad, photographs and videos capture a city halted beneath the gleaming glass towers of multinational corporations and luxury residential complexes. According to police estimates, more than three lakh vehicles were stuck in the traffic jam, disrupting large parts of Hyderabad’s western corridor. Spread bumper to bumper, they would have covered about 824 acres, or 3.34 square km – an area equivalent to about 55 cricket fields the size of Hyderabad’s Rajiv Gandhi International Cricket Stadium.
For many travelers, the level of disruption seemed out of proportion to the rain that caused it.
“Such thunderstorms are a common summer phenomenon after prolonged intense heat,” explains GNRS Srinivas, senior meteorologist at the India Meteorological Department (IMD), Hyderabad Centre. He further said, “The temperature in Telangana remained between 41°C and 46°C for several days, causing severe heating of the land surface. The difference in temperature between the landmass and the surrounding seas resulted in moist winds from the Arabian Sea and the Bay of Bengal, leading to the formation of cumulonimbus clouds and short-lived but intense rainfall.”
He says that unlike monsoon rains, which are widespread and frequent, pre-monsoon rains are highly localized. “The rainfall on June 9 was concentrated in some parts of the city, while many areas received very little rainfall. Such events generally occur in the afternoon and evening due to rising heat and last for a short period.”
But Srinivas argues that intensity of rainfall alone does not explain the city’s flooding problem. He says that about 11 cm of rain recorded in parts of Hyderabad on Tuesday (June 9, 2026) is also not extraordinary from a meteorological point of view.
The flood is, in many ways, a billion-year-old geological legacy with a 25-year-old urban twist. The rocks and hills that once defined the landscape have given way to modern concrete towers, but the slopes and natural drainage patterns still remain. Unlike relatively flat parts like Charminar, Secunderabad, Nampally, Balanagar, Khairatabad, Musheerabad and Maredpally, western Hyderabad is shaped by a dense network of hills, valleys and natural channels. On Tuesday evening (June 9, 2026), rain water passed through these slopes and accumulated under flyovers, along roads and around commercial centres.
“Floods are caused by the contrast between the highlands and low-lying areas. Water naturally flows from the higher ground to the plains. Earlier, most of this water would flow into the inaccessible Cheruvu,” says Hari Sarvothamman, visiting faculty at the Center for Earth, Ocean and Atmospheric Sciences, University of Hyderabad.
“But now office and residential buildings have come up on natural paths, blocking the flow of water and flooding low-lying areas. Gentle slopes and plains have been built up, and urban planning authorities have given permission (for construction) without respecting the geological framework,” says Mr. Sarvothaman, who has studied floods in Hyderabad, including the August 2000 flood.
He says that the root of the problem lies with the very birth of Cyberabad.
As Hyderabad moved forward in the IT sector in the late 1990s, Cyberabad emerged as the city’s major technology hub. The Cyberabad Development Authority, created on 20 January 2001, was tasked with developing a “model enclave commensurate with the concentration of such institutions”.
Cost of construction against the figure
Renowned architectural consultancy Vastu Silpi Consultants, led by BV Doshi, prepared the master plan, zoning framework and building rules. Conceived around the natural topography of the area, the plan consisted of two high-density corridors with a matching grid. Cyber Towers were constructed in 1998 itself, while the master plan came into effect on 29 October 2001.
Nearly 25 years later, the city is paying the price for design flaws, omissions and arrogance, critics say. While a master plan existed, geologists were not part of the planning process. And then amendments were made in the plan itself. For example, a 2013 government order re-designated the proposed 24-metre CDA master plan road passing through parts of Gopanapalli and Manikonda as a residential-use zone. The change occurred near areas that were flooded on Tuesday evening (June 9, 2026).
The consequences become apparent during intense rainfall events. “5 cm rainfall in one square km produces about 50,000 cubic meters or about 50 million liters of water, which is equivalent to about 10,000 water tankers emptied simultaneously in an urban area,” said a community note prepared by IMD’s Srinivas.

With concrete surfaces and paved compounds replacing increasingly permeable ground, natural absorption is severely restricted, causing runoff to accumulate rapidly, and cause flooding to a depth of 60 cm to 100 cm and widespread traffic disruption, it reads.
Srinivas believes that urban flooding is not an inevitable consequence of climate change, but a manageable infrastructure challenge. Their blueprint proposes a four-month strategy that includes public awareness campaigns, compliance windows for large assets, digital verification mechanisms, targeted audits and penalties for continued non-compliance.
However, on June 9 the city had little time to respond. Torrential rain started around 5 pm, when lakhs of employees in the IT corridor were leaving their offices and entering the road network. Within minutes, water started accumulating at sensitive locations, while traffic volume increased in western Hyderabad.
Queues formed at key locations including Biodiversity Junction, Cyber Gateway, Hitech City Main Road and the IKEA flyover before spreading onto connecting roads and flyovers in Cyberabad. By 6 pm, the IT corridor had come to an almost complete standstill. As more workers took to the streets, the crowd grew by the minute.
A traveler recalls, “It took me four hours to cover just three km from Hitech City to Gachibowli. Mindspace Road was literally a swimming pool.” Another spent about two hours 15 minutes in the 1.8 km journey from Raidurg Metro station to IKEA.
struggle to resolve the impasse
Cyberabad Traffic DCP S. According to Seshadrini Reddy, the authorities had little opportunity to intervene once the scale of the crisis became clear. “By the time we realized what was happening, all the vehicles were already on the road. There was no chance to change course,” she says.
An advisory was issued around 4.30 pm urging staggered office timings, but by then it was too late. Ms Reddy adds, “We had no accurate forecast and the authorities were caught off guard.”
The congestion proved so severe that even emergency response teams and personnel tasked with clearing waterlogging and restoring traffic struggled to reach affected locations. It took more than 90 minutes for Ms Reddy to travel from Miyapur to Gachibowli despite using internal roads.
“What happened that night was essentially firefighting after the situation had already developed,” she says.
The hours-long traffic jams in Indian cities are no longer limited to local newspapers. As Hyderabad and Telangana aggressively pursue global capability centers and global investments, such episodes reach far beyond the city limits, shaping the perception of the city’s infrastructure and resilience.
Cyberabad Municipal Corporation Commissioner G. Srijana acknowledged that the incident had exposed weaknesses despite monsoon preparedness meetings held earlier this month. However, she rejects the suggestion that the rainfall was moderate and describes it as a cloudburst-like event in which about 57 mm of rain fell within an hour. “We did a reality check on Tuesday,” she says; I should accept it.” He further said that while sensitive spots were identified on paper, the June 9 rains offered important lessons in real-world situations.
Acknowledging public criticism, Srijana says that in many places water ran off faster than in previous rain events. However, the presence of a water stagnation point for a few minutes can turn into a traffic jam lasting several hours, she notes.
new vulnerabilities
The rains also revealed new flood-prone places. In some instances, engineering interventions appeared to shift the problem rather than eliminate it. For example, drainage works near Nectar Gardens resolved flooding in one part but resulted in waterlogging behind it. “We have learned our lesson and are taking corrective action,” she says.
“Can anything be done about Hyderabad’s frequent floods?”. Mr. Sarvosthan laughs at this question. “Maybe they can build trenches near the foothills and drain the water into the lower catchment areas. But where will they get the land to build the trenches,” he asks.
