Motorists in Abu Dhabi were asked to take caution on Monday morning after waking up to foggy conditions.
The National Centre of Meteorology and Seismology issued a low visibility warning, reporting dense fog between Abu Dhabi and Jebel Ali, via Twitter, and said there would be scattered fog in the west of the region.
The conditions are expected to last into the night, especially in the western and coastal areas, and continue until Wednesday.
Last Friday thick fog resulted in a mass car pile-up on the Abu Dhabi-Dubai highway. Around 30 cars were involved in the collision, which resulted in several injuries.
