Uttar Pradesh began the New Year under severe cold conditions, with dense fog disrupting daily life across many regions. The India Meteorological Department (IMD) forecast very dense fog in eastern UP and potential rainfall in western districts due to a western disturbance. While Purvanchal faces persistent fog, western UP, including Saharanpur and Muzaffarnagar, may experience rain. A yellow alert for dense fog has been issued for numerous districts statewide, though some daytime relief from sunlight is expected.
