Gurugram, Aug. 10 -- Heavy rain lashed Gurugram on Saturday, causing waterlogging in several areas and bringing down the city's maximum temperature by 8.3degC compared to the previous day, the India Meteorological Department (IMD) said. While most parts of the city saw smooth traffic movement, minor snarls were reported in the evening on the Delhi-Jaipur Expressway. The city received 14.5mm of rainfall between 8.30am and 5.30pm on Saturday, according to IMD officials. An orange alert had been issued earlier in view of the probability of showers. Between 8.30am on Friday and 8.30am on Saturday, the city had recorded 7mm of rain. The IMD forecast thunderstorms, lightning, and heavy rain at isolated places in Gurugram and neighbouring areas, with further heavy rainfall expected on Wednesday and Thursday. The maximum temperature on Saturday was 27degC and the minimum was 25degC. Officials said the downpour improved air quality, with the city's air quality index settling at a "satisfactory" level of 54. Traffic movement was mostly smooth throughout the day due to low vehicular volume on account of the Raksha Bandhan festival. "No snarls were reported anywhere in the city on Saturday and the traffic movement mainly remained smooth everywhere," said DCP (Traffic) Rajesh Kumar Mohan. "Preparations were already in place looking at the festival of Raksha Bandhan," Mohan added, noting that personnel were deployed at key intersections and stretches prone to congestion. However, brief traffic snarls were reported for about an hour in the evening near Sirhaul border, Narsingpur, Rajiv Chowk, and other locations on the Delhi-Jaipur Expressway before being cleared. Some residents reported chaos in certain localities. Sukhbir Singh, a city resident, said Sector 9 Road was "a complete chaos" due to potholes and waterlogging. "There were no police personnel deployed anywhere between Sector 4 and Sector 9 to manage traffic chaos," he alleged. No major disruptions, including power outages, were reported in the city during the rain spell. Overnight rain crippled Delhi on Raksha Bandhan, flooding roads, shutting two underpasses, and triggering traffic snarls despite civic "monsoon preparedness" claims. In southeast Delhi's Jaitpur, a shrine wall collapsed around 9.13am, killing seven, including two children, and injuring others. Survivors described "screams, debris and darkness." DCP Hemant Tiwari said eight were pulled out; an FIR is being registered and the landowner will be questioned. Delhi Fire Services said debris had to be broken apart for rescues. Bharaitya Janata Party MP Ramvir Singh Bidhuri promised compensation. In Ballimaran, meanwhile, a two-storey house collapsed, damaging nearby structures; police said....
