A dust storm has engulfed the UAE for the past three days.
The National Centre of Meteorology said the dust clouds originated in Saudi Arabia a few days ago. But the wind direction then changed. Much of the western Arabian Peninsula is now clear but the UAE is still being hit because of these winds.
The dusty weather, which is common during the summer, can also lead to flare ups of allergies. Allergic rhinitis, for example, is often misdiagnosed as a common cold but in some cases can lead to severe reactions such as difficulty in breathing. People are urged to consult their doctors, and decrease their exposure to the conditions.
Meanwhile, forecasters expect that the haze will clear by Tuesday.
