While Qatar grapples with dense sea fog, UAE weather department has also issued a warning of fog formation with visibility as less as 50m.
This seasonal fog has led to flight disruptions with planes either being diverted or delayed.
Hamad International Airport in Qatar that sees a movement of 1000 to 1200 flights per day has diverted two flights to Abu Dhabi and Bahrain and has reported a delay in few others.
At sunrise Wednesday, downtown Dubai was so foggy that even the outline of the Burj Khalifa, the world's tallest building, could not be seen by passers-by. Fog also engulfed Abu Dhabi, the capital of the United Arab Emirates.
At Dubai International Airport, home to the long-haul carrier Emirates, flights were delayed by up to an hour. Delays also hit Abu Dhabi's international airport.
The UAE's National Center of Meteorology & Seismology earlier had warned that visibility Wednesday morning would be less than 50 meters (55 yards).
High humidity and falling temperatures cause the fog to roll in seasonally along the coast of the Arabian Peninsula.
