Cold Wave and School Closures
A “cold day” is defined when the minimum temperature is below 10°C, and the deviation from the normal maximum or minimum temperature is at least 4.5°C. Delhi and neighboring regions continue to experience biting cold conditions.
In Gautam Buddh Nagar, authorities have ordered the suspension of classes for students up to Grade 8 in all schools until further notice. The IMD predicts a minimum temperature of 8°C on Friday, with fog expected to persist through January 8.
Travel Chaos and Public Response
The dense fog has not only impacted travel schedules but also posed challenges for commuters on the ground. Visibility on roads has been drastically reduced, leading to slower traffic and increased travel times. Travelers have expressed frustration over delays but acknowledge the safety measures taken by airlines and railways under the adverse weather conditions.
As North India continues to grapple with dense fog and plummeting temperatures, authorities are urging caution and advising citizens to stay updated on travel advisories.
