Chandigarh, Jan. 28 -- With 40 mm rain till evening, Chandigarh saw its wettest January day in four years on Tuesday. The downpour also dragged the city's maximum temperature down by five notches to 15.5degC. According to the India Meteorological Department (IMD), this is the highest single-day January rain since January 23, 2022, when 45.9 mm was logged. Residents can expect rainy conditions on Wednesday as well as the Western Disturbance continues to remain active. The spell also marked the wettest day of the current winter season, surpassing the 38.3 mm recorded on January 23. IMD officials said showers started in the morning and occurred intermittently throughout the day. The Sector 39 observatory recorded 5.7 mm rain till 5.30 pm, while the airport saw 11 mm. Fog was present early in the morning, reducing visibility to 800 metres. Wind speeds reached up to 50 km/h during the day. IMD Chandigarh director Surender Paul said brief relief is expected later in the week, but another Western Disturbance could bring more rain around February 1, potentially pushing the mercury further down. While the maximum temperature saw a drop, the minimum temperature rose from 6.2degC on Monday to 10.1degC, 2.3degC above normal, on Tuesday. Over the next three days, the maximum temperature is expected to hover between 16degC and 20degC, while the minimum will remain between 8degC and 9degC. Meanwhile, the air quality index (AQI), which had briefly improved to the "satisfactory" category, slipped back to "moderate" on Tuesday with values between 101-200, according to the Central Pollution Control Board (CPCB). Since AQI is calculated as a 24-hour average, officials expect levels to return to satisfactory on Wednesday....
