As the Christmas celebrations wound down, the National Weather Service in Oklahoma City issued a dense fog advisory that is set to linger until 10 AM the following morning. The fog, described as “visibility one quarter mile or less in dense fog,” has covered parts of central, east central, northern, northwest, southeast, southern, southwest, and western Oklahoma, reported by the NWS. Pedestrians and motorists, wrapped up in the cocoon of mist, are advised to exercise caution as the low visibility conditions could make navigating the roads particularly hazardous.
