Bengaluru Weather: Bengaluru was lashed by heavy rain on Monday evening, leaving several neighbourhoods waterlogged and traffic crawling. The India Meteorological
Department (IMD) has issued a yellow alert for the city and much of Karnataka until Thursday, with more wet days ahead. The evening downpour lasted less than an hour but left a mark on the city. Vidyapeeta recorded 34.5 mm of rain, Kengeri 33 mm, and Rajarajeshwarinagar 32 mm. Other parts of Bengaluru received between 10 and 30 mm, according to data from the Karnataka State Natural Disaster Monitoring Centre (KSNDMC). Commuters were left wading through waterlogged streets as traffic snarled at key junctions.
Bengaluru Rains: Roads Flooded in An Hour
The newly inaugurated double-decker flyover at Central Silk Board, designed to ease Bengaluru’s chronic gridlock, turned into what many online called a “swimming pool”. Videos and photos showed waterlogging both on and under the structure, forcing vehicles to inch their way through stagnant water.
“This water build-up happens at a specific point where there is no drain. The slope isn’t maintained, and the drains are only on one side,” wrote one social media user, flagging engineering flaws. Another quipped, “How can a flyover get flooded? Engineering marvel at best.”

The 5.12-km flyover, built at a cost of Rs 449 crore by the Bangalore Metro Rail Corporation Limited (BMRCL), carries road traffic on its lower deck while the Namma Metro Yellow Line runs above. Opened in July 2024, it was intended to decongest one of Bengaluru’s busiest stretches. But with key ramps still incomplete, Monday’s flooding has sparked fresh debate about the city’s infrastructure readiness.
Karnataka’s Wetter-Than-Normal Monsoon
While Bengaluru reeled under Monday’s showers, data shows Karnataka as a whole has received more rain than usual this monsoon. Between June 1 and September, the state recorded 730 mm of rain—five per cent higher than the seasonal average of 696 mm, as per TIE report.
North Interior Karnataka saw the biggest jump with 406 mm, about 19 per cent more than normal. Coastal and Malnad districts also received slightly above-average rainfall. Seven districts, six of them in the north, recorded excess rainfall of more than 20 per cent. In contrast, Chamarajanagar in the south reported a deficit.
More Rain on the Horizon
The IMD has forecast isolated heavy rain in coastal Karnataka until Sunday, while parts of South Interior Karnataka, including Bengaluru, could see heavier showers on Wednesday. Officials have advised citizens to be cautious in low-lying areas vulnerable to flooding.
With the yellow alert in place until Thursday, Bengalureans may have to brace for more traffic snarls, waterlogging, and flooded infrastructure in the days to come.
