Dense fog has covered Delhi and neighboring NCR areas such as Ghaziabad and Meerut, significantly reducing visibility and causing travel difficulties. Reports indicate that drivers on the Delhi-Meerut Expressway faced sudden fog, forcing them to adjust their speeds. Social media posts and real-time photos show barren trees disappearing into the mist, prompting discussions about whether the phenomenon is unusual spring fog or an increase in smog due to adverse weather conditions.

In Ghaziabad, the fog affected local neighborhoods, highways, and industrial zones, delaying school openings and necessitating caution for drivers. A similar scenario was reported in Meerut, where visibility dropped in several areas, raising concerns among residents. With temperatures gradually rising in February and spring approaching, there is a notable presence of fog, leading to questions about the unusual occurrence.

Experts attribute this prolonged period of fog in northern India, including Uttar Pradesh, to factors like extended cold waves, increased humidity, and atmospheric disturbances. They emphasize that this fog should not be linked to external causes, dispelling rumors and focusing on local climatic changes and meteorological patterns impacting visibility in the region.
