Noida/Ghaziabad, June 30 -- The southwest monsoon finally made its foray into the National Capital Region on Sunday, bringing much-needed relief from the heat, while also causing brief waterlogging and traffic disruptions in parts of Gautam Budh Nagar and Ghaziabad. The India Meteorological Department (IMD) confirmed the monsoon's arrival in Delhi on June 30, with weather data showing cooler-than-usual conditions across the region. Noida recorded 6mm of rainfall between 8.30am and 5.30pm on Sunday, according to IMD reports. The minimum temperature in the region hovered around 25.4degC, with the maximum at 29.9degC. The neighbouring Ghaziabad reported a slightly higher minimum of 26.4degC. In Noida, intermittent rain around 4pm led to brief traffic snarls, especially near Sector 38A close to The GIP Mall, along Botanical Garden road, Maharaja Agrasen Marg, and the stretch from Film City flyover to Sector 18 underpass. Sector 62 also saw commuters struggling through a heavily waterlogged road stretch. However, Noida traffic police said the impact was minimal owing to lower traffic volumes on Sunday. "The traffic remained largely unaffected, but due to bikers halting near underpasses and flyovers, traffic slowed down in some areas. Additional traffic police personnel were deployed to clear the traffic and prevent any congestion," said Vinay Tomar, sub-inspector (traffic). The Noida Authority claimed that waterlogging did not create a major havoc in the city, stating that all underpass motors were operational. "Noida roads, both internal and arterial, and all the underpasses remained free of waterlogging during the rain on Sunday evening. The reason is proactive drain cleaning and installation of water pumping machines at 28 low-lying spots," said RP Singh, general manager of Noida Authority's water department. Despite the official claims, brief waterlogging was reported in low-lying areas such as Sectors 6, 7, 8, 9, 14, 16, 19, 20, 21, and 25. Residents expressed concern over the drainage infrastructure. "As it starts raining in GB Nagar, water begins to accumulate, causing inconvenience to pedestrians. The authority has not resolved these long-standing waterlogging issues despite repeated complaints," said Amit Chauhan, an advocate and a resident of Sector 19. In Ghaziabad, meanwhile, Loni saw severe waterlogging. In Delhi, the rainfall tally for June reached 98.2mm after the city received 5.3mm on Sunday - an excess of about 32% over the long-period average (LPA) of 74.1mm. Last year, however, the city recorded a staggering 243.3mm, including 228.1mm on a single day when the monsoon entered Delhi on June 28. This year's June temperature patterns also aligned with a cooler-than-normal trend. Delhi's average maximum temperature for June stood at 37.8degC - 1.2degC below the LPA of 39degC - while the average minimum was 27.2degC, about 0.5degC below normal, IMD officials said. "Even before the monsoon, consistent rainfall and overcast conditions helped regulate daytime temperatures," an IMD official noted. The IMD has forecast similar weather in early July, with light rain and cloudy skies expected until July 5. Delhi typically receives 640.4mm of rainfall during the monsoon and 774.4mm annually. As the city braces for more showers, authorities in Delhi claim extensive pre-monsoon preparation. The Municipal Corporation of Delhi (MCD) reported having removed 156,000 tonnes of silt from drains - exceeding its target of 126,000 tonnes. Yet officials cautioned that some waterlogging is still likely in low-lying areas. "We are neither God nor have control over Lord Indra," an MCD official said. Power discoms have also issued monsoon advisories urging people to steer clear of electrical installations like poles and transformers, ensure their home wiring is secure, and prevent children from playing near electrical equipment....
