Gurugram, June 16 -- A spell of rain and breezy conditions early Monday brought Gurugram's minimum temperature down to 17degC, nearly 9.9 degrees below normal and among the season's lowest since May, according to the India Meteorological Department. Gurugram received 11mm of rainfall between Sunday and 8.30am Monday. Wazirabad recorded the highest rainfall at 9mm, followed by Pataudi (6mm), Kadipur (5mm), Harsaru (5mm), Farrukh Nagar (4mm) and Manesar (2mm), while Sohna recorded a trace. Light rain began at 7.05am, with a second spell between 2pm and 5pm bringing another 4mm, slowing traffic across several stretches. IMD said Gurugram recorded the lowest minimum temperature in Haryana on Monday. The maximum temperature was 38.5degC. The meteorological department attributed conditions to an active western disturbance over northern Haryana combined with moisture-laden winds from the Bay of Bengal and Arabian Sea. Light to moderate rainfall is forecast at a few places on June 15 and 19, and at isolated locations between June 16 and 18. A 'yellow' alert remains in place till June 19, though maximum temperatures are expected to rise 2degC to 4degC over the next four days. IMD warned of thunderstorms, lightning and squalls with gusts up to 40 km/h until Thursday. Rain and waterlogging disrupted peak-hour traffic, with congestion on NH-48 from Kirti Nagar to Sarhol and Clover Leaf Interchange to Behrampur, and on Gurugram-Faridabad Road, Ghata T-point and roads near Leisure Valley Park. Waterlogging was reported in Police Lines, Patel Nagar, Sector 10, Sheetla Mata Road and Mahavir Chowk. "Instructions have been issued to civic bodies to fix drainage networks on key city intersections, such as Rajiv Chowk and stretches from Signature Towers to Leisure Valley Park. Police will decide deployment based on situational needs, and priority will be given to ensuring smooth traffic movement. Adequate pumping options are being arranged to prevent snarls during monsoon," said Satyapal Yadav, assistant commissioner of police (traffic headquarters and highways). The district's average air quality index stayed largely unchanged at 195 in the "moderate" category, against 194 on Sunday. At 10pm, Sector 51 (227) and Vikas Sadan (286) logged moderate air quality, while Teri Gram (95) and NISE Gwal Pahari (132) remained in satisfactory and moderate categories respectively, per the Central Pollution Control Board....
