Gurugram, Jan. 4 -- Gurugram district on Saturday logged its coldest day of the season with the minimum temperature dropping to 3.8degC, nearly 2.7degC lower than the previous day, according to the Indian Meteorological Department. The maximum temperature was recorded at 15.6degC. Very dense fog was observed on Saturday morning, with visibility dropping to around 800 metres at about 8 am, officials said. The IMD has issued an orange alert for the city for the next two days, warning of very dense fog at isolated locations across Haryana, including Gurugram, Faridabad, Mewat, Palwal, Nuh, Jhajjar, Rewari and Sirsa. Officials said minimum temperatures are expected to dip further, while maximum temperatures are likely to hover between 16degC and 18degC and minimum between 2degC and 4degC. "The weather is expected to remain largely unchanged, with minimum temperatures likely to dip. Strong winds and dense fog are also forecasted, so commuters are advised to maintain safe distances, use fog lights, and avoid travelling during early morning or late-night hours on highways," said Surinder Paul, director of IMD Chandigarh. Experts linked the improvement to changing weather conditions. "Shifts in weather have strengthened wind flow across northern India, leading to faster dilution of pollutants," an IMD official said. Despite this, the district recorded an air quality index of 244 on Saturday at 4pm, placing it in the "poor" category, according to the Central Pollution Control Board (CPCB)....
