A severe cold wave and dense fog have led to school closures and altered timings across several districts in Uttar Pradesh. Varanasi has closed schools up to Class 5, while other districts like Prayagraj, Lucknow, Kanpur, and Meerut have extended closures to Class 8 or adjusted class schedules to between 10 am and 3 pm. These measures are in response to plummeting temperatures and dangerously low visibility, with IMD issuing yellow and orange alerts for the region.
